Merge branch 'f-dsv41-tune' into f-024-rel

launch: an installed DeepSeek model whose config names a gone engine, with no package in this install, is not 'already installed': setup runs (feed download, or one plain line with the next step) instead of the start failing on a missing file; tests
DeepSeek quality numbers from the final-tip scores (H100, 4,995 positions): 2.00 KL 0.170 ppl +15.5% (code +8.6%, agent +5.3%), 2.25 KL 0.107 ppl +7.3% (code +3.2%, agent +2.2%); README x7, DEEPSEEK41.md, release notes, setup and fit text

-Strata runs the Qwen3.8-Flash-Next mixture-of-experts model (and its Coder, Swift 1.5 and Unsloth variants) on a
-normal PC: one NVIDIA or AMD graphics card plus system RAM, on Windows or Linux. It has a C++/CUDA/HIP engine
-(`src/`, `include/`), a Python server with an OpenAI- and Anthropic-compatible API and a web app (`serve/`), and a
-one-click installer (`setup.py`, started by `START-HERE.bat` / `setup.sh`).
+Strata runs the Qwen3.8-Flash-Next mixture-of-experts model (and its Coder, Swift 1.5, Unsloth, Gyro and NVFP4
+variants, and Qwen3.6-35B-A3B) on a normal PC: one NVIDIA or AMD graphics card plus system RAM on Windows or Linux,
+or an Apple Silicon Mac. Version 0.2.3, engine 0.1.48. It has three parts:
+
+- **The app** (`apps/desktop`, the Tauri shell; `apps/host`, the Node host and the web UI). It is for people who do
+  not want a terminal. The installer has the engine inside.
+- **The Terminal** (`strata.py`, `strata_cli/`, `strata_control/`): the `strata` command. It sets up a model, serves
+  it and watches it. Agents use this part.
+- **The engine and the server** (`src/`, `include/`, `metal/`, `sycl/` for the C++/CUDA/HIP/SYCL/Metal engine;
+  `serve/` for the Python server with an OpenAI- and Anthropic-compatible API and a web page). `setup.py`, started by
+  `START-HERE.bat` or `setup.sh`, is the older one-click installer from source.

 ## Installing Strata for a user

-Follow **[docs/AI_SETUP.md](docs/AI_SETUP.md)**: check the PC, pick the model by RAM, run setup non-interactively,
-start and verify the server, and connect the user's apps. Never expose the server beyond `127.0.0.1` without
-`--api-key`. As an alternative to shell commands, Strata's MCP server ([docs/MCP_SERVER.md](docs/MCP_SERVER.md))
-offers the same steps as tools.
+Follow **[docs/AI_SETUP.md](docs/AI_SETUP.md)**. For an agent that has a shell, the short version is:
+
+1. Install the Terminal. It needs no administrator rights.
+
+   ```sh
+   curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh                  # Linux, Mac
+   irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex                         # Windows PowerShell
+   ```
+
+   On Windows, open a new terminal afterwards so that `strata` is on the PATH.
+2. Check what would happen. Nothing is changed:
+
+   ```sh
+   strata launch --plan --model q2_0
+   ```
+
+3. Set up and serve without questions. It downloads the engine for the card and the model (tens of GB), starts the
+   server, prints the addresses and returns. The server keeps running.
+
+   ```sh
+   strata launch --model q2_0 --yes --no-tui
+   ```
+
+   Useful flags (all of them: `strata launch --help`): `--family`, `--model-path` (files the user already has),
+   `--data-dir`, `--context 32k|64k|128k`, `--vision off|on|gpu|cpu`, `--parallel N`, `--gpu 0,1`,
+   `--access local|lan|cloudflare|tailscale`, `--port`, `--api-key-env NAME`, `--new-key`, `--save-preset NAME`,
+   `--output json`. `strata launch --status` shows what is serving, `strata launch --stop` stops it, and
+   `strata launch --show-key` prints the API key.
+4. Connect the user's apps: `strata connect` lists them, `strata connect <app> --check` sends one prompt and one tool
+   call the way that app does.
+
+Keep the server on `127.0.0.1` unless the user asks for more. Beyond it an API key is recommended: `--access lan` makes one for you, and `--no-api-key` serves without one (a warning, never a refusal; on a public tunnel the warning is stronger). The old route (clone
+the repository and run `START-HERE.bat --yes` or `./setup.sh --yes`) still works and is the fallback when the
+Terminal cannot run. Strata's MCP server ([docs/MCP_SERVER.md](docs/MCP_SERVER.md)) offers the same steps as tools.

 ## Working on the code

 - How the engine works, every measured number, the API and all settings: [docs/DETAILS.md](docs/DETAILS.md) and
  the [paper](docs/paper/Strata-Paper.pdf).
- AMD (HIP) build and validation: [docs/AMD_HIP.md](docs/AMD_HIP.md); multi-GPU: [docs/MULTI_GPU.md](docs/MULTI_GPU.md).
- Setup's own tests run without a GPU or downloads: `python tools/test_setup_<name>.py` (for example
-  `tools/test_setup_amd.py`, `tools/test_setup_choices.py`).
- Keep the docs' style: plain words, measured numbers with what they were measured on, no claims without a
-  measurement.
+- The Terminal: [docs/TERMINAL.md](docs/TERMINAL.md) and [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md). The app,
+  the packages and the update feed: [packaging/README.md](packaging/README.md) and [packaging/UPDATES.md](packaging/UPDATES.md).
+- AMD (HIP) build and validation: [docs/AMD_HIP.md](docs/AMD_HIP.md); multi-GPU: [docs/MULTI_GPU.md](docs/MULTI_GPU.md);
+  Mac (Metal): [docs/MAC.md](docs/MAC.md).
+- Tests: the Terminal and Control tests are in `tests/terminal` (`python -m pytest tests/terminal`). The app's UI
+  tests run with `npm test` in `apps/host`. Setup's own tests run without a GPU or downloads:
+  `python tools/test_setup_<name>.py` (for example `tools/test_setup_amd.py`, `tools/test_setup_choices.py`).
+- Keep the docs' style: plain words, short sentences, written for non-technical users first. Give measured numbers
+  with what they were measured on. Make no claim without a measurement.

 ## Contributing a change or report

- Search the open issues and pull requests first, and add to a thread that already covers your point.
- Open an issue with the form that fits (bug report, feature request or question).
- One change per pull request. Say what it changes and what it leaves alone.
+The rules are in **[CONTRIBUTING.md](CONTRIBUTING.md)**. Read it before you open an issue or a pull request, and
+follow it whether a person or an agent writes the text. The short version:
+
+- Start every issue and pull request title with its area: `[Engine]`, `[GUI]`, `[TUI]`, `[Benchmark]`, `[Docs]` or
+  `[Other]`, for example `[Engine] fix …`. A check on GitHub fails a pull request whose title has no area.
+- Search the open and closed issues and pull requests first, and add to a thread that already covers your point.
+- Agree the scope in an issue before a large feature, a refactor or a change to a default.
+- One problem per pull request. Lead with the problem and the result, then the approach, then the validation
+  (passed, failed and not run, kept apart) and the limits.
 - A new feature is opt-in, and the default path stays byte-identical to the last release. Say how you checked.
 - Build every backend a file touches (CUDA, HIP, SYCL) before asking for review.
 - Change a default only where you measured it faster, and show the numbers with what they were measured on.
+- Never submit measurements, logs or reproduction steps you did not produce. Mark a finding from reading code as
+  unconfirmed static analysis.
 - A report from hardware the maintainers do not have is welcome. Follow
  [docs/COMMUNITY_BENCHMARKS.md](docs/COMMUNITY_BENCHMARKS.md), compare against a same-day run of the build you are
  testing, and say what you did not test.

+# Contributing to Strata
+
+**AI assistance is welcome. The contributor is responsible for understanding the change and supplying real evidence.**
+
+These rules apply to issues, pull requests, benchmark reports, and the agents helping prepare them.
+You should be able to explain every changed line and answer review questions about it.
+
+## Before starting
+
+1. Search [issues](https://github.com/Niko1221/Strata/issues) and
+   [pull requests](https://github.com/Niko1221/Strata/pulls), including closed discussions. Add new evidence to an
+   existing thread when it covers your problem.
+2. Read [AGENTS.md](AGENTS.md) and the documentation for the component you want to change.
+3. Get maintainer agreement on scope before substantial features, refactors, architecture changes, or changes to
+   defaults. Describe the user problem, proposed behavior, and tradeoffs in an issue first. Agreement on scope
+   does not guarantee a merge. Focused fixes and benchmark reports can go straight to a PR.
+4. Keep one problem per PR. Update that PR after feedback; do not open competing attempts for the same change.
+
+Do not resubmit a declined proposal under a different title or through another agent. If new evidence changes
+the situation, bring it to the original discussion and let a maintainer decide whether to reopen it.
+
+## Report a problem people can investigate
+
+Use the matching [issue form](https://github.com/Niko1221/Strata/issues/new/choose). A bug report should include:
+
+- The smallest steps or command that reproduce the problem, and the expected and actual behavior.
+- Strata version or commit, OS, GPU and VRAM, and relevant model, quantization, and configuration.
+- The exact error and relevant logs, with credentials and private content removed.
+- Whether you reproduced it yourself. Label a finding based only on reading code or a scanner as
+  **unconfirmed static analysis**, and explain the suspected path without presenting it as an observed failure.
+
+Do not invent reproduction steps, errors, affected hardware, or severity. If you cannot reproduce something,
+say what you inspected and what would verify the hypothesis. Feature requests should explain a concrete user
+need and the current workaround. Questions should say what you tried and where you got stuck.
+
+Example structure, with placeholders to replace with actual observations:
+
+```text
+Problem: <one observed behavior>
+Environment: <commit, OS, GPU/VRAM, model/quant, relevant settings>
+Reproduce: <exact command or short sequence>
+Expected: <documented or intended behavior>
+Actual: <observed behavior and exact error>
+Evidence: <sanitized log attachment>
+Reproduction status: <reproduced locally OR unconfirmed static analysis>
+```
+
+## Titles
+
+Every issue and pull request title starts with its area in square brackets, then a short description: `[Engine]`, `[GUI]`, `[TUI]`,
+`[Benchmark]`, `[Docs]` or `[Other]`. For example `[Engine] fix decode stop on long prompts` or `[GUI] keep the model list after a tab
+switch`. The issue forms ask for the area and a check on the title fails when the prefix is missing.
+
+## Prepare a focused pull request
+
+Lead with the problem and resulting behavior. Explain why the approach is needed, the important limits, and
+any compatibility effects. Link the issue and scope agreement when applicable. A file-by-file narration or
+an AI-generated summary of the diff is not a substitute for this explanation.
+
+- Keep unrelated formatting, cleanup, dependency changes, and speculative abstractions out of the PR.
+- Add documentation where it changes what a user or developer needs to know. Avoid repeated summaries,
+  speculative roadmaps, and generated documentation with no actionable information.
+- Preserve existing behavior outside the intended change. New features are opt-in; follow the default-path
+  and performance requirements in [AGENTS.md](AGENTS.md).
+- Read the complete diff, including generated files, before submitting. Remove debugging output, secrets,
+  private paths, and accidental files.
+- Prefer a small relevant regression check over tests that only restate the implementation. Documentation-only
+  changes need link, example, and consistency checks; they do not require GPU builds.
+
+## Show the validation you actually performed
+
+List exact commands, the revision and environment tested, and observed outcomes. Keep **passed**, **failed**,
+and **not run** separate. Include relevant output or a log attachment. A command you suggest running is not
+evidence that it passed; a CI run on a different revision is not validation of the submitted code.
+
+Build every backend a code change touches, including CUDA, HIP, and SYCL where applicable, before requesting
+review. For changes that need hardware execution, report that execution separately from compilation. A mock,
+static check, or successful build does not establish hardware correctness. If you lack a required environment,
+keep the PR as a draft, identify the missing checks, and ask for targeted help in the same thread. Do not claim
+compatibility you have not tested.
+
+Performance claims need before/after runs on the same hardware and workload, with every changed setting
+identified. Preserve the individual runs, failures, and variability. Follow the
+[community measurement guide](docs/COMMUNITY_BENCHMARKS.md); standard submissions will use the
+[benchmark protocol](docs/BENCHMARK_PROTOCOL.md) once it is activated. One fast run does not justify changing a
+default or claiming a speedup for other machines.
+
+Example PR body; placeholders are not test results:
+
+```text
+Problem and result: <trigger; behavior before and after the change>
+Related discussion: <issue URL and scope agreement, when required>
+Approach: <why this fix; relevant compatibility effects>
+Validation:
+  Passed: <exact command, revision/environment, observed result, log>
+  Failed: <exact command and failure, or none observed>
+  Not run: <check, reason, and what remains unverified>
+Limits: <known limitations or remaining work>
+```
+
+## Rules for AI-assisted work
+
+Use agents to help investigate, implement, and explain work that you can review. Before submitting, verify
+their claims against the source, actual command output, or a cited primary reference.
+
+Never submit fabricated measurements, invented test results, fake logs, or copied claims you have not checked.
+Do not turn a repository scan into a batch of speculative issues or PRs. Consolidate related findings, establish
+their effect, and submit the useful evidence. Do not present an agent's confidence or another model's approval
+as validation. Keep review replies concise and address the requested change or evidence directly.
+
+Maintainers may request a smaller change, return a PR to draft, or close a submission that lacks evidence,
+duplicates existing work, or ignores agreed scope. A smaller, understandable contribution with honest limits
+is easier to review and maintain.
+
+## Share a benchmark
+
+A results-only PR should contain the human report, raw measurements, sanitized configuration, and supporting
+logs. Keep it separate from engine changes and include poor results and failed requests.
+
+The [current community benchmark guide](docs/COMMUNITY_BENCHMARKS.md) remains available for measurements made
+with today's tools. The [new protocol](docs/BENCHMARK_PROTOCOL.md) defines the draft standard and future approval
+workflow. Its draft status must remain visible: existing reports are not automatically standard or approved.

-## Wie schnell ist es?
+**Neu hier?** Sieh dir an, [was du brauchst](#was-du-brauchst), und [installiere dann die App](#option-a-die-strata-app).

-Wir haben es auf zwei ganz normalen Gaming-PCs gemessen. Ein Token ist etwa ¾ eines Wortes.
+- **Läuft auf einem Gaming-PC.** 32 GB Arbeitsspeicher (RAM) und Grafikspeicher zusammen reichen für den Anfang.
+- **Passt zu deinen Werkzeugen.** Strata spricht die OpenAI- und die Anthropic-API, deshalb verbinden sich Claude Code, Codex CLI, OpenCode und andere Agents damit.
+- **Liest Bilder.** Das ist standardmäßig eingeschaltet.
+- **Kostenlos.** MIT-Lizenz, kein Konto, keine Cloud.
+- **Privat.** Keine Telemetrie. Was Strata herunterlädt, wann es das Internet nutzt und wie es Downloads prüft, steht in [docs/SAFETY.md](docs/SAFETY.md).

 ## Was du brauchst

-| | |
+**Du brauchst mindestens 32 GB Arbeitsspeicher (RAM) und Grafikspeicher (VRAM) zusammen.** Bei einem Mac oder einem Ryzen AI Max
+ist das der gemeinsame Speicher. Mit mehr Speicher läuft ein größeres oder ein schnelleres Modell.
+
+- Ein PC mit 32 GB und einer Grafikkarte mit 12-16 GB führt den Coder aus.
+- Mit 64 GB RAM laufen alle Größen.
+
+| Dein Computer | Details |
 | --- | --- |
-| **Grafikkarte** | **NVIDIA** GeForce RTX 20, 30, 40 oder 50 Serie, oder **AMD** Radeon RX 7900 XT / XTX, RX 7800 XT / 7700 XT, RX 9060 XT, RX 9070 / 9070 XT, Radeon AI PRO R9700 oder RX 6800 / 6900 Serie. Sie braucht **12 GB VRAM oder mehr**. |
-| **RAM** | 32 GB oder mehr. Dein RAM entscheidet, [welches Modell](#welches-modell-soll-ich-nehmen) passt. Mit 64 GB laufen alle Größen. |
-| **Festplatte** | Etwa 80 GB frei. Nimm wenn möglich eine SSD: Der erste Start geht dann viel schneller. |
-| **System** | Windows 10 / 11 oder Linux und ein aktueller Grafiktreiber von NVIDIA oder AMD. |
+| **NVIDIA** GeForce RTX 20, 30, 40, 50 Serie (12 GB oder mehr) | Installiere die App oder das Terminal. |
+| **AMD** Radeon RX 6800 und neuer, Radeon AI PRO R9700 (12 GB oder mehr) | [AMD-Karten](docs/AMD_HIP.md) |
+| **Intel** Arc | [Intel Arc](docs/INTEL_ARC.md), [Intel-Engine](docs/INTEL.md) |
+| **Apple-Silicon-Mac** (M1 oder neuer, macOS 15 oder neuer) | [Mac](docs/MAC.md) |
+| **AMD Ryzen AI Max (Strix Halo)** und andere Systeme mit gemeinsamem Speicher | [Strix Halo](docs/STRIX_HALO.md) |
+| Ältere Karten und Prozessoren | [Ältere GPUs](docs/OLDER_GPUS.md), [Ältere CPUs](docs/INSTALL.md#older-cpus-experimental) |

-Alles andere richtet der Installer ein. Zwei oder drei Karten können sich das Modell teilen ([Multi-GPU](docs/MULTI_GPU.md)).
+Außerdem nötig:

-Experimentell, von Community-Mitgliedern auf ihren eigenen Rechnern geschrieben und getestet:
+- etwa 80 GB freier Speicherplatz (mit einer SSD startet es beim ersten Mal viel schneller)
+- Windows 10 / 11, Linux oder macOS
+- ein aktueller Grafiktreiber

- **Ältere Grafikkarten** (Tesla P40 / V100, GTX 10, Radeon VII / MI50, RX 6700 XT, RX 5500 XT): [Ältere GPUs](docs/OLDER_GPUS.md).
- **Intel Arc**, unter Linux aus dem Quellcode gebaut: [Intel Arc](docs/INTEL_ARC.md).
- **AMD Ryzen AI Max (Strix Halo)**, unter Linux aus dem Quellcode gebaut: [Strix Halo](docs/STRIX_HALO.md).
- **Ältere Prozessoren ohne AVX2**: Sie funktionieren, aber langsam. [Ältere CPUs](docs/INSTALL.md#older-cpus-experimental).
+Zwei oder drei Karten desselben Herstellers können sich ein Modell teilen ([Multi-GPU](docs/MULTI_GPU.md)). Strata teilt ein
+Modell nie auf NVIDIA- und AMD-Karten auf. Die vollständige Liste: [docs/INSTALL.md](docs/INSTALL.md#what-you-need).

-Die vollständige Liste: [docs/INSTALL.md](docs/INSTALL.md#what-you-need).
+## Installation

-## Installieren
+Such dir eine Option aus. Alle starten dieselbe Engine und nutzen dieselben Modelle.

-### Lass deine KI es einrichten
+### Option A: die Strata-App

-Nutzt du einen KI-Coding-Assistenten (Claude Code, Cursor, Codex, GitHub Copilot, ...)? Füge dort diesen Text ein:
+Der einfachste Weg. Die App bringt die Engine mit: installieren, ein Modell wählen, chatten. Lade die Datei für dein
+System und deine Grafikkarte von der [Releases-Seite](https://github.com/Niko1221/Strata/releases/latest) herunter. Du bist
+unsicher, welche du brauchst? Lies den Absatz unter der Tabelle.
+
+| System | Deine Grafikkarte | Datei zum Herunterladen |
+| --- | --- | --- |
+| **Windows 10 / 11** | NVIDIA RTX, Treiber 580 oder neuer | [`Strata-0.2.3-windows-cuda13.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda13.exe) |

+| | AMD Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-linux-amd-strixhalo.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-strixhalo.AppImage) |
+| **Mac** (Apple Silicon, macOS 15 oder neuer) | eingebaut | [`Strata-0.2.3-mac.dmg`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-mac.dmg) |
+
+**Wenn du unsicher bist:** Bei NVIDIA nimmst du `cuda13`, wenn dein Treiber Version 580 oder neuer ist, sonst `cuda12`.
+`cuda12` ist für ältere Karten und ältere Treiber. Die Dateien `hip` und `amd` sind für AMD-Karten. Für andere AMD-Karten
+(RX 6000) gibt es noch keine fertige App: siehe [AMD-Karten](docs/AMD_HIP.md).
+
+Danach:
+
+- **Windows:** Starte die `.exe`. Sie wird für deinen Benutzer installiert und braucht keine Administratorrechte. Wenn
+  Windows "Der Computer wurde durch Windows geschützt" meldet, wähle **Weitere Informationen** und dann **Trotzdem
+  ausführen** (der Installer ist noch nicht signiert).
+- **Linux:** Mach die Datei ausführbar (`chmod +x`) und starte sie. Sie braucht FUSE 2: `sudo apt install libfuse2`
+  (Ubuntu 22.04) oder `libfuse2t64` (Ubuntu 24.04 und neuer).
+- **Mac:** Öffne die `.dmg` und zieh Strata in den Ordner "Programme".
+
+Auf dem ersten Bildschirm liest die App deinen PC aus und empfiehlt ein passendes Modell. Drück auf Installieren. Das Modell
+ist ein großer Download (etwa 40-70 GB) und wird nach einer Unterbrechung dort fortgesetzt, wo er aufgehört hat. Wenn du
+das Fenster schließt, beenden sich Strata und die Engine.
+
+### Option B: das Terminal (eine Zeile)
+
+Das Terminal ist der Befehl `strata`, gedacht für Skripte, Server und KI-Agents.
+
+Linux und Mac:
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows (PowerShell):
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+Das Skript prüft deinen PC, lädt das Terminal herunter, kontrolliert die SHA-256-Prüfsumme und entpackt es in deinen
+Home-Ordner. Es braucht keine Administratorrechte. Öffne unter Windows danach ein neues Terminalfenster. Dann startest du
+Strata:
+
+```sh
+strata launch
+```
+
+Es stellt dir eine Frage nach der anderen: Modell, Kontext, Bilder, wer sich verbinden darf. Danach lädt es die Engine für
+deine Grafikkarte herunter (signiert und vor der Nutzung probeweise gestartet), dazu das Modell, und beginnt zu laufen.
+Für Skripte und KI-Agents gibt es Flags:
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+Wenn du das Installationsskript vor dem Ausführen lesen willst, lade es zuerst mit `curl -fsSL <address> -o install.sh`
+herunter, lies es und führe dann `sh install.sh` aus. Alle Bildschirme und Flags: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md).
+
+### Option C: deine KI richtet es ein
+
+Füge das in Claude Code, Cursor, Codex, GitHub Copilot oder einen anderen Coding-Assistenten ein:

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.
 ```

-Er prüft deine Grafikkarte, deinen RAM und deine Festplatte und wählt das passende Modell. Dann installiert und
-startet er es und sagt dir, wie du deine Apps verbindest. KI-Tools können Strata auch über seinen
+Der Assistent prüft deine Grafikkarte, deinen Arbeitsspeicher und den Speicherplatz, wählt das passende Modell, installiert
+und startet es und sagt dir, wie du deine Apps verbindest. KI-Werkzeuge können Strata auch über den
 [MCP-Server](docs/MCP_SERVER.md) installieren, starten und stoppen.

-### Oder mach es selbst
+Du willst es lieber selbst bauen? Siehe [Aus dem Quellcode bauen](#aus-dem-quellcode-bauen).

-[Lade Strata herunter](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) und entpacke es (oder nutze
-`git clone`). **Windows:** Doppelklick auf **`START-HERE.bat`**. **Linux:** Führe im Strata-Ordner **`./setup.sh`** aus.
+## Modelle

-Die Schritte sind für NVIDIA und AMD gleich. Der Installer erkennt deine Karte und richtet die passende Engine
-dafür ein. Er stellt dir ein paar Fragen:
+Die App und `strata launch` empfehlen ein Modell passend zu deinem Speicher. Es ist ein einziges Modell in mehreren
+Größen, mehr oder weniger stark komprimiert. Kleinere Größen sind schneller. Größere Größen sind etwas klüger.

- welches Modell und welche Größe,
- wie viel Kontext (wie viel Text sich das Modell merkt),
- ob es Bilder lesen soll.
+### Wenig Speicher? Probier Gyro

-Drück jedes Mal Enter, um die empfohlene Antwort zu nehmen. Dann lädt er das Modell herunter (etwa 70 GB) und
-startet es. Bricht der Download ab, starte ihn einfach neu: Er macht dort weiter, wo er aufgehört hat. Dein Browser
-öffnet die Strata-App unter `http://127.0.0.1:8080`.
+[Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF) (von agentionai) ist die kleinste Möglichkeit, dieses Modell auszuführen.

-> **Während das Modell startet, kann dein PC 1-3 Minuten langsam sein oder nicht reagieren** (beim ersten Mal am
-> längsten). Strata lädt 35-55 GB in deinen RAM und reserviert einen Teil davon für die Grafikkarte. Das ist normal.
-> Warte und schließ das Fenster nicht. Im Fenster siehst du, was Strata gerade tut.
+| Größe | Benötigter Speicher (RAM + VRAM) | Download | Was es ist |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27,6 GB | 58,5 GB | Für PCs, auf denen nichts anderes läuft. Die Qualität ist geringer als bei IQ2_XS. |
+| **Gyro-M** | 35 GB | 92,0 GB | Ungefähr die Qualität von IQ3_XXS bei etwa 20 % weniger GPU-Speicher. Es schreibt Antworten langsamer als Q2_0: 16 % auf einer RTX 3060 mit 12 GB, 21 % auf einer R9700. |

-**Beim nächsten Mal** startest du wieder `START-HERE.bat` (oder `./setup.sh`). Es startet sofort und lädt nichts
-doppelt herunter. Schließ das Fenster, um das Modell zu stoppen. `UPDATE.bat` (`./update.sh`) aktualisiert Strata,
-ohne es zu starten. Updates, Docker, mehrere Karten, wo die Dateien landen und alle Optionen:
-[docs/INSTALL.md](docs/INSTALL.md).
+Gyro läuft auf NVIDIA- und AMD-Karten (bei AMD experimentell) auf Intel-Arc-Karten unter Linux (getestet auf einer Arc A750) und ab 0.2.2 auf Macs mit Apple Silicon (Gyro-S auf einem Mac mini mit 32 GB: 9 Tokens/s, die Experten werden von der SSD gelesen). Details und Messwerte:
+[docs/GYRO.md](docs/GYRO.md). Starte es mit `strata launch --model gyro-s`.

-## Welches Modell soll ich nehmen?
+### Die anderen Größen

-Der Installer empfiehlt eins passend zu deinem RAM. Dasselbe Modell gibt es in mehreren Größen, mehr oder weniger
-stark komprimiert. Kleinere Größen sind schneller. Größere sind etwas klüger.
-
-| Dein RAM | Nimm | Warum |
+| Dein Speicher (RAM + VRAM) | Nimm | Hinweise |
 | --- | --- | --- |
-| **32 GB** | **Coder** | passt in 32 GB und ist für Code gemacht (mit einer 24-GB-Karte laufen auch Q2_0 und IQ2_XS) |
-| **48 GB** | **IQ2_XS** (oder Q2_0, das schnellste) | die größeren Größen passen nicht |
-| **64 GB** | **IQ2_XS** (empfohlen) oder IQ3_XXS / IQ3_S | alle Größen passen; IQ3_S ist das beste und das langsamste |
-| **96 GB oder mehr** | **IQ3_S** oder Unsloths UD-IQ4_XS (~4 Bit) | Platz für die größten Größen, auch wenn alles andere offen ist |
+| **32 GB** | **Gyro-S**, oder den **[Coder](docs/MODELS.md#coder)** für Code | Der Coder braucht 32 GB RAM und behält die Hälfte der Experten, deshalb ist er außerhalb von Code schwächer |
+| **40 GB** | **[Swift 1.5](docs/MODELS.md#swift-15)** IQ2_XS (39,2 GB), oder **Gyro-M** (35 GB) | Swift denkt kürzer nach, bevor es antwortet. Gyro-M kommt der Qualität von IQ3_XXS nahe, schreibt Antworten aber 16-21 % langsamer als Q2_0 |
+| **48 GB** | **IQ3_XXS** (47,0 GB) | Langsamer, besser |
+| **64 GB** | **IQ3_S** (54,8 GB), das Original oder Swift 1.5 | Am langsamsten, am besten. Es erreicht in den veröffentlichten Tests das volle Modell |
+| **96 GB oder mehr** | **UD-IQ4_XS** von Unsloth (etwa 72 GB RAM) bis **Q8_0** (etwa 136 GB), 4 bis 8 Bit | Näher am vollen Modell. Bei weniger RAM liest Strata einen Teil von der SSD, das ist viel langsamer |

- **[Coder](docs/MODELS.md#coder):** eine Version für Code, bei der die Hälfte der Experten entfernt wurde. Sie
-  erreicht 91 % des SWE-bench-Verified-Werts des vollen Modells (von ihren Autoren gemessen) und passt in 32 GB RAM.
-  Außerhalb von Code ist sie schwächer, auch bei chinesischem und anderem CJK-Text (#438). Nimm dafür Q2_0, IQ2_XS
-  oder IQ3_S, die alle Experten behalten.
- **[Swift 1.5](docs/MODELS.md#swift-15):** ein Fine-Tune, das viel kürzer nachdenkt, bevor es antwortet. Du
-  bekommst die Antwort früher, bei etwa gleicher Qualität.
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs):** die ~4-Bit-Version von Unsloth, in der Qualität
-  zwischen IQ3_S und UD-Q4_K_XL. 94 GB Download. Mit weniger als ~80 GB RAM liest Strata einen Teil davon während
-  der Antwort von der SSD, dort ist es also langsamer (eine NVMe-SSD hilft).
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)** (experimentell): am nächsten am vollen
-  Modell. Aber Strata liest das meiste davon während der Antwort von der SSD, deshalb schreibt es auf einem PC mit
-  64 GB nur 7-8.5 Tokens/s.
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs):** Das richtest du von Hand
-  ein. Es steht nicht im Menü des Installers.
+Auch mit weniger RAM, als eine Zeile nennt, kann es funktionieren: Strata wechselt von selbst in seinen
+[Modus für wenig RAM](docs/MODELS.md#a-big-graphics-card-and-little-ram). Rechne mit weniger Tempo, mit einer kleinen
+Grafikkarte mit deutlich weniger.

-Größen, Downloads und was wohin passt: [docs/MODELS.md](docs/MODELS.md). Um später ein weiteres Modell
-hinzuzufügen, starte `SETUP.bat` (Linux: `./setup.sh --setup`).
+Weitere Auswahl:

-## So benutzt du es

- **Im Browser:** Öffne `http://127.0.0.1:8080`. Dort gibt es **Chat**, einen Live-**Monitor** für das Modell und
-  deine GPU/CPU/RAM und **About** mit den Einstellungen und Adressen.
- **Deine Apps und Coding-Agents:** Füge einen „OpenAI-kompatiblen“ Anbieter mit der Basis-URL
-  **`http://127.0.0.1:8080/v1`** hinzu. Jeder API-Key und jeder Modellname funktioniert.
-  - Apps, die die API von Anthropic nutzen: `http://127.0.0.1:8080/v1/messages` (Claude Code:
-    `ANTHROPIC_BASE_URL=http://127.0.0.1:8080`).
-  - Codex CLI und andere Apps, die die OpenAI Responses API nutzen: `/v1/responses`
-    ([Einrichtung](docs/DETAILS.md#the-responses-api-and-codex-cli)).
- **Nachdenken:** Wähle **aus, niedrig, mittel oder hoch** im Chat-Menü oder unter „Reasoning Effort“ in deiner
-  App. Aus ist am schnellsten. Hoch ist am besten für schwierige Fragen.
- **Bilder:** Antworte im Setup mit Ja auf „Images?“. Klick dann im Chat auf **Picture** oder hänge Bilder in deiner
-  App an. AMD-Karten lesen Bilder unter Linux über den Prozessor; unter Windows geht das noch nicht.
- **Vom Handy oder einem anderen PC:** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>`. Setz immer einen
-  Key.
- **Eine Anfrage nach der anderen:** Standardmäßig beantwortet Strata eine Anfrage, die anderen warten. Um mehrere
-  gleichzeitig zu beantworten, setz `"parallel": 2` ([BATCHING.md](docs/BATCHING.md)). Auf einer 12-GB-Karte wird
-  dadurch jede Antwort langsamer.
- **Lange Prompts:** Strata liest die erste Nachricht eines Chats komplett, etwa 1 Minute pro 30,000 Tokens.

-Mehr: [wo deine Chats gespeichert werden](docs/INSTALL.md#where-things-are-stored), [die API](docs/DETAILS.md#using-it).
+[DeepSeek V4.1-Flash](https://huggingface.co/ISTA-DASLab/DeepSeek-V4.1-Flash-1017-GSQ-RCO-GGUF) ist ein anderes, deutlich größeres Modell. ISTA-DASLab hat die drei Sets unten gebaut. Strata startet sie auf einem PC mit einer 12-GB-Grafikkarte und 46 bis 64 GB RAM und liest den Rest von der SSD. Es läuft auf NVIDIA-RTX-Karten der Serien 30 bis 50 und auf der Radeon AI PRO R9700. Es nutzt ein eigenes Engine-Paket, `strata-dsv41`, das `strata launch` lädt, wenn du DeepSeek wählst. Die Desktop-App bietet es noch nicht an.

- **Mein PC ist beim ersten Start von Strata eingefroren.** Das ist normal, während das Modell lädt. Warte und
-  schließ das Fenster nicht. Nach 10 Minuten immer noch eingefroren? Starte den PC neu, schließ andere Programme und
-  versuch es noch einmal, oder nimm eine kleinere Größe.
- **Es hat beim Herunterladen oder Installieren aufgehört.** Starte `START-HERE.bat` (oder `./setup.sh`) noch
-  einmal. Es macht dort weiter, wo es aufgehört hat.
- **Es ist sehr langsam und die Festplattenlampe blinkt ständig, oder es meldet „the engine stopped

-## Wie funktioniert es?
+## Wie schnell ist es?

-Modelle wie dieses laufen normalerweise auf Servern mit Hunderten Gigabyte Grafikspeicher. Deine Grafikkarte hat
-12-24 GB. Strata bringt das Modell trotzdem unter, indem es **die Arbeit auf deinen ganzen PC verteilt**. Stell dir
-eine Küche vor: Was du ständig brauchst, bleibt auf der Arbeitsfläche, der Rest wartet in der Vorratskammer.
+Gemessen mit einer Grafikkarte mit 12 GB (RTX 5070, Ryzen 5 7600, 64 GB RAM). Ergebnisse anderer Karten findest du hier:

+
+## Benutzung
+
+### In der App
+
+Die App hat einen **Chat**, einen **Monitor** für das Modell sowie für GPU, CPU und RAM, eine Seite **Modelle** und die
+**Einstellungen**. Der Chat kann in einem Ordner auf deinem PC arbeiten. Im Modus **Manuell** fragt er nach, bevor er eine
+Datei ändert oder einen Befehl ausführt. Mit `/loop 10m <what to do>` wiederholst du eine Nachricht alle 10 Minuten, solange
+der Chat geöffnet ist.
+
+Der Chat kann das Web mit DuckDuckGo (oder Bing) durchsuchen, ohne Konto. Unter **Einstellungen, Tools** kannst du einen
+Suchschlüssel hinzufügen. Die Suche ist die einzige Funktion, die etwas von deinem PC sendet (die Suchbegriffe).
+
+Um zwei Modelle auszuführen, schalte **Mehrere Modelle ausführen** ein und gib jedem Modell eine eigene Karte desselben
+Herstellers.

+
+`strata --help` listet alles auf. Starten und Bereitstellen laden nichts herunter. Nur die Installation, `strata launch`
+(wenn du ein Modell wählst) und `strata update` tun das. Um Strata von deinem Handy oder einem anderen PC aus zu erreichen,
+nutze `strata launch --access lan`. Der Befehl erzeugt einen API-Schlüssel und startet in einem Netzwerk nicht ohne einen.
+Ein Browser öffnet sich nur, wenn du `--open` angibst. Anleitung: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md). Der ganze Client: [docs/TERMINAL.md](docs/TERMINAL.md).
+
+### Mit KI-Agents
+
+Ein Agent installiert Strata mit dem Einzeiler aus Option B und führt
+`strata launch --model NAME --yes --no-tui` aus. Die Schritte, Flags und Exit-Codes stehen in [docs/AI_SETUP.md](docs/AI_SETUP.md),
+die Regeln für das Repository in [AGENTS.md](AGENTS.md).

+
+### Bilder
+
+Bilder sind für Modelle, die sie lesen können, standardmäßig eingeschaltet. Hänge ein Bild im Chat an oder füge es ein, oder
+sende es aus deiner App. Der Bildleser läuft auf dem Prozessor, wenn deine Grafikkarte weniger als 24 GB hat (einige Sekunden
+pro Bild, ohne Speicher der Karte zu belegen), und ab 24 GB auf der Grafikkarte. Die Regel gilt für NVIDIA und AMD gleich.
+Du kannst Bilder pro Modell ausschalten oder den Leser mit `--vision off`, `--vision gpu` oder `--vision cpu` wählen.
+
+Die Zahlen hinter der Regel: Auf einer Radeon AI PRO R9700 brauchte der Bildleser der Karte 57 ms für ein Bild mit 260 Tokens,
+der des Prozessors 3,1 s. Auf Karten mit 16 GB (Tesla P100 und RTX A4000, Linux) kostete der Bildleser der Karte 3-5 % des
+Texttempos, weil er etwa 1,4 GB belegt, die sonst das Modell nutzen würde. Auf dem Mac liest die GPU, egal wie viel Speicher er hat (0,45 s für ein Bild mit 260 Tokens auf einem M4 mit 32 GB, etwa 1,2 GB des gemeinsamen
+Speichers); der Prozessor braucht dort etwa 50 s pro Bild und liest deshalb nur mit `--vision cpu`.
+
+### Gut zu wissen
+
+- Das Denkniveau (**aus, niedrig, mittel oder hoch**) stellst du im Chat-Menü oder unter "reasoning effort" in deiner App ein. Aus ist am schnellsten.
+- Strata beantwortet standardmäßig eine Anfrage nach der anderen. Für mehrere gleichzeitig nutze `--parallel N` in `strata launch` oder
+  `"parallel": 2` in der Konfiguration ([BATCHING.md](docs/BATCHING.md)). Auf einer Karte mit 12 GB wird dadurch jede Antwort langsamer.
+- Strata liest die erste Nachricht eines Chats komplett, etwa 1 Minute pro 30.000 Tokens. Folgenachrichten starten in Sekunden.

+## Aus dem Quellcode bauen
+
+<details>
+<summary>Windows, Linux und Mac aus dem Repository</summary>
+
+[Lade Strata herunter](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) und entpacke es, oder nutze `git clone`.
+**Windows:** Doppelklick auf `START-HERE.bat`. **Linux:** Führe `./setup.sh` im Strata-Ordner aus.
+
+**Mac (Apple Silicon, macOS 15 oder neuer):** Installiere einmal die Command Line Tools von Apple mit `xcode-select --install`
+(Xcode selbst brauchst du nicht). Öffne das Terminal im Strata-Ordner und führe `./setup.sh` aus. Das Skript baut die
+Mac-Engine auf deinem Mac (etwa 7 Minuten), stellt dieselben Fragen, lädt das Modell herunter und startet es. Beim nächsten
+Mal startet `./setup.sh` sofort. Welche Größe zu deinem Mac passt: [docs/MAC.md](docs/MAC.md).
+
+Der Installer erkennt deine Karte und richtet die passende Engine ein. Er fragt, welches Modell und welche Größe du willst,
+wie viel Kontext (wie viel Text sich das Modell merkt) und ob es Bilder lesen soll. Drück Enter für die empfohlene Antwort.
+Dann lädt er das Modell herunter (etwa 70 GB) und startet es. Wenn der Download abbricht, führe das Skript erneut aus, dann
+geht es weiter. Dein Browser öffnet die Strata-Seite unter `http://127.0.0.1:8080`.
+
+> Während das Modell startet, kann dein PC 1-3 Minuten langsam sein oder nicht reagieren (beim ersten Mal am längsten). Strata
+> lädt 35-55 GB in deinen RAM und sperrt einen Teil davon für die Grafikkarte. Warte ab und schließe das Fenster nicht.
+
+Starte beim nächsten Mal wieder `START-HERE.bat` (oder `./setup.sh`). Es startet sofort und lädt nichts doppelt herunter.
+Schließ sein Fenster, um das Modell zu beenden. `UPDATE.bat` (`./update.sh`) aktualisiert Strata, ohne es zu starten.
+Aktualisieren, Docker, mehrere Karten, wohin die Dateien kommen und alle Optionen: [docs/INSTALL.md](docs/INSTALL.md).
+
+Um deinen PC zu messen, führe `BENCH.bat` (`./bench.sh`) aus. Das dauert 5-10 Minuten und schreibt einen Bericht, den du teilen
+kannst ([so geht's](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)).
+
+**Optional: mehr Tempo auf einer Karte, wenn das ganze Modell in den RAM passt.** Zwei Einstellungen zum Einschalten von
+RubenTorney (#1904, #1905). Sie helfen, wenn du eine Grafikkarte nutzt und dein RAM alle Experten aufnimmt, zum Beispiel bei
+Q2_0 oder IQ3_XXS auf einem PC mit 64 GB. Öffne `strata-<model>.json` im Strata-Datenordner ([wo](docs/INSTALL.md#where-things-are-stored)) und ergänze:
+
+- `"--adapt-async", "1"` in der Liste `"args"`. Der Expertencache wird dann in einem Hilfsthread aktualisiert, statt die
+  Antwort anzuhalten. Gemessen auf einer RTX 5070 (Windows, Q2_0): +4-5 % beim Decodieren, +7-10 % bei Code und langen
+  Dokumenten. Die Antworten können sich leicht von der Standardeinstellung unterscheiden und bleiben von Lauf zu Lauf gleich.
+- `"STRATA_PIN_BY_NEED": "1"` im Block `"env"` (Windows). Windows kann nur etwa die Hälfte des RAM für die Grafikkarte sperren,
+  und diese Einstellung sperrt zuerst die Experten, die die Karte am dringendsten braucht. Gemessen auf der RTX 5070: +4,4 % beim Lesen des Prompts.
+
+```json
+"args": [ ..., "--adapt-async", "1" ],
+"env": { "STRATA_PIN_BY_NEED": "1" }
+```
+
+Starte Strata nach der Änderung neu. Zum Rückgängigmachen entfernst du die beiden Einträge.
+
+</details>
+
+## Wie funktioniert das?
+
+Modelle wie dieses laufen normalerweise auf Servern mit Hunderten Gigabyte Grafikspeicher. Deine Grafikkarte hat 12-24 GB.
+Strata bringt das Modell auf deinen PC, indem es die Arbeit auf den ganzen Rechner verteilt. Stell dir eine Bibliothek vor.
+
+- Das Modell ist ein Team aus 24.576 kleinen Spezialisten ("Experten"), wie 24.576 Nachschlagewerke. Für jedes Wort braucht es nur 10 davon.
+- **Deine Grafikkarte ist der Schreibtisch.** Er ist klein und schnell. Die etwa 4.000 am häufigsten genutzten Bücher liegen
+  dort aufgeschlagen.
+- **Dein RAM sind die Regale im Lesesaal.** Alle 24.576 Bücher stehen dort. Braucht ein Wort ein Buch, das nicht auf dem
+  Schreibtisch liegt, holt dein Prozessor es sofort aus dem Regal, während die Karte weiterarbeitet.
+- **Deine SSD ist das Archiv.** Sie enthält eine Nachschlagetabelle von 29 GB. Das Modell liest pro Wort nur wenige Zeilen
+  daraus, deshalb muss sie nicht im RAM liegen.
+
+<p align="center"><img src="docs/media/how-it-works.svg" width="860" alt="The model's 24,576 experts: the busiest on the graphics card, all of them in RAM, a lookup table on the SSD"></p>
+
+Ein kleiner Helfer rät außerdem die nächsten Wörter. Das große Modell prüft sie alle auf einmal und behält die richtigen. Du
+bekommst dieselbe Antwort, 1,6-1,8-mal früher. Lange Texte werden in großen Stücken gelesen, bis zu 8.192 Tokens auf einmal,
+mit über 1.000 Tokens pro Sekunde.

+## Etwas ist schiefgegangen?
+
+- **Mein PC ist beim ersten Start von Strata eingefroren.** Strata lädt das Modell in den RAM. Warte ab und schließe das
+  Fenster nicht. Nach 10 Minuten immer noch eingefroren? Starte den PC neu, schließe andere Programme und versuch es noch
+  einmal, oder wähle eine kleinere Größe.
+- **Es ist beim Herunterladen oder Installieren stehen geblieben.** Starte die App oder `strata launch` noch einmal, oder
+  führe `START-HERE.bat` (oder `./setup.sh`) erneut aus. Es macht dort weiter, wo es aufgehört hat.
+- **Es ist sehr langsam, die Festplattenanzeige blinkt ständig, oder es meldet "the engine stopped unexpectedly".** Dein PC
+  hat nicht genug freien RAM. Schließe andere Programme (Browser brauchen viel) oder wähle eine kleinere Größe wie Q2_0 oder IQ2_XS.
+- **Es meldet, dass es keine Engine für diesen PC gibt.** Öffne in der App **Einstellungen, Engine** und drücke **Engine
+  aktualisieren**. Führe im Terminal `strata update` aus. `strata doctor` zeigt, welche Engine-Dateien installiert sind.
+- **Es meldet, dass Port 8080 schon belegt ist.** Strata läuft bereits. Such das Fenster.
+
+Weitere Probleme und Lösungen: [docs/TROUBLESHOOTING.md](docs/TROUBLESHOOTING.md). Du kommst nicht weiter? Öffne ein
+[Issue](https://github.com/Niko1221/Strata/issues). Hänge in der App die Datei aus **Einstellungen, Engine, Diagnose, Protokolle anzeigen, Protokolle speichern** an. Füge im Terminal die Ausgabe von `strata doctor` ein. Hänge beim Start aus dem Quellcode die
+Datei `strata-<model>.log` aus dem Strata-Ordner an. Ein Sicherheitsproblem meldest du bitte privat: [SECURITY.md](SECURITY.md).

-Strata ejecuta **[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)** en un PC normal. Es un
-modelo de IA grande e inteligente que normalmente necesita un servidor. Conversa, escribe código, entiende imágenes
-y funciona con tus aplicaciones y agentes de programación. Nada sale de tu PC.
+Strata ejecuta **[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)**, un modelo de 125 mil millones
+de parámetros que normalmente necesita un servidor, en un PC normal. Conversa, escribe código, lee imágenes y funciona
+con tus aplicaciones y tus agentes de programación. Tus chats y tus archivos se quedan en tu PC.

-## ¿Qué velocidad tiene?
+**¿Eres nuevo?** Mira [lo que necesitas](#lo-que-necesitas) y luego [instala la aplicación](#opción-a-la-aplicación-strata).

-Lo medimos en dos PC gaming normales. Un token equivale más o menos a ¾ de una palabra.
+- **Funciona en un PC gaming.** Con 32 GB entre RAM y memoria gráfica ya puedes empezar.
+- **Funciona con tus herramientas.** Habla las API de OpenAI y de Anthropic, así que Claude Code, Codex CLI, OpenCode y otros agentes se conectan a él.
+- **Lee imágenes.** Viene activado por defecto.
+- **Gratis.** Licencia MIT, sin cuenta, sin nube.
+- **Privado.** Sin telemetría. Lo que Strata descarga, cuándo usa internet y cómo comprueba las descargas está en [docs/SAFETY.md](docs/SAFETY.md).

- **Escribe respuestas:** lo rápido que aparece la respuesta en un chat corto. 60 tokens por segundo es más rápido de lo que puedes leer.
- **Lee tu prompt:** lo rápido que procesa lo que le envías (aquí, un documento, código o historial de chat de 32K tokens).

+| Tu ordenador | Detalles |
 | --- | --- |
-| **Tarjeta gráfica** | **NVIDIA** GeForce serie RTX 20, 30, 40 o 50, o **AMD** Radeon RX 7900 XT / XTX, RX 7800 XT / 7700 XT, RX 9060 XT, RX 9070 / 9070 XT, Radeon AI PRO R9700 o serie RX 6800 / 6900. Necesita **12 GB de VRAM o más**. |
-| **RAM** | 32 GB o más. Tu RAM decide [qué modelo](#qué-modelo-elijo) cabe. Con 64 GB funcionan todos los tamaños. |
-| **Disco** | Unos 80 GB libres. Usa un SSD si puedes: el primer arranque es mucho más rápido. |
-| **Sistema** | Windows 10 / 11 o Linux, y un controlador gráfico actual de NVIDIA o AMD. |
+| **NVIDIA** GeForce RTX serie 20, 30, 40, 50 (12 GB o más) | Instala la aplicación o la Terminal. |
+| **AMD** Radeon RX 6800 y posteriores, Radeon AI PRO R9700 (12 GB o más) | [Tarjetas AMD](docs/AMD_HIP.md) |
+| **Intel** Arc | [Intel Arc](docs/INTEL_ARC.md), [motor Intel](docs/INTEL.md) |
+| **Mac con Apple Silicon** (M1 o posterior, macOS 15 o posterior) | [Mac](docs/MAC.md) |
+| **AMD Ryzen AI Max (Strix Halo)** y otros sistemas con memoria unificada | [Strix Halo](docs/STRIX_HALO.md) |
+| Tarjetas y procesadores antiguos | [GPU antiguas](docs/OLDER_GPUS.md), [CPU antiguas](docs/INSTALL.md#older-cpus-experimental) |

-El instalador prepara todo lo demás. Dos o tres tarjetas pueden repartirse el modelo ([multi-GPU](docs/MULTI_GPU.md)).
+También hace falta:

-Experimental, escrito y probado por miembros de la comunidad en sus propios equipos:
+- unos 80 GB de disco libre (con un SSD el primer arranque es mucho más rápido)
+- Windows 10 / 11, Linux o macOS
+- un controlador gráfico actual

- **Tarjetas gráficas antiguas** (Tesla P40 / V100, GTX 10, Radeon VII / MI50, RX 6700 XT, RX 5500 XT): [Older GPUs](docs/OLDER_GPUS.md).
- **Intel Arc**, compilado desde el código fuente en Linux: [Intel Arc](docs/INTEL_ARC.md).
- **AMD Ryzen AI Max (Strix Halo)**, compilado desde el código fuente en Linux: [Strix Halo](docs/STRIX_HALO.md).
- **Procesadores antiguos sin AVX2**: funcionan, pero despacio. [Older CPUs](docs/INSTALL.md#older-cpus-experimental).
-
-La lista completa: [docs/INSTALL.md](docs/INSTALL.md#what-you-need).
+Dos o tres tarjetas de la misma marca pueden compartir un modelo ([multi-GPU](docs/MULTI_GPU.md)). Strata nunca reparte un
+modelo entre tarjetas NVIDIA y AMD. Lista completa: [docs/INSTALL.md](docs/INSTALL.md#what-you-need).

 ## Instalación

-### Deja que tu IA lo instale
+Elige una opción. Todas arrancan el mismo motor y usan los mismos modelos.

-¿Usas un asistente de programación con IA (Claude Code, Cursor, Codex, GitHub Copilot, ...)? Pega esto en él:
+### Opción A: la aplicación Strata
+
+La forma más fácil. La aplicación lleva el motor dentro: la instalas, eliges un modelo y chateas. Descarga el archivo para
+tu sistema y tu tarjeta gráfica desde la [página de versiones](https://github.com/Niko1221/Strata/releases/latest). ¿No
+sabes cuál elegir? Mira el párrafo que hay debajo de la tabla.
+
+| Sistema | Tu tarjeta gráfica | Archivo que descargar |
+| --- | --- | --- |
+| **Windows 10 / 11** | NVIDIA RTX, controlador 580 o posterior | [`Strata-0.2.3-windows-cuda13.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda13.exe) |

+
+**Si no estás seguro:** con NVIDIA, elige `cuda13` si la versión de tu controlador es la 580 o posterior, y `cuda12` en caso
+contrario. `cuda12` es para tarjetas y controladores más antiguos. Los archivos `hip` y `amd` son para tarjetas AMD. Las
+demás tarjetas AMD (RX 6000) todavía no tienen una aplicación ya preparada: mira
+[Tarjetas AMD](docs/AMD_HIP.md).
+
+Después:
+
+- **Windows:** ejecuta el `.exe`. Se instala para tu usuario y no necesita permisos de administrador. Si Windows muestra
+  "Windows protegió tu PC", elige **Más información** y luego **Ejecutar de todas formas** (el instalador todavía no está
+  firmado).
+- **Linux:** haz el archivo ejecutable (`chmod +x`) y lánzalo. Necesita FUSE 2: `sudo apt install libfuse2` (Ubuntu 22.04)
+  o `libfuse2t64` (Ubuntu 24.04 y posteriores).
+- **Mac:** abre el `.dmg` y arrastra Strata a Aplicaciones.
+
+En la primera pantalla, la aplicación analiza tu PC y recomienda un modelo adecuado. Pulsa Instalar. El modelo es una
+descarga grande (unos 40 a 70 GB) y, si se interrumpe, continúa donde se quedó. Al cerrar la ventana, Strata y el motor se
+detienen.
+
+### Opción B: la Terminal (una línea)
+
+La Terminal es el comando `strata`, pensado para scripts, servidores y agentes de IA.
+
+Linux y Mac:
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows (PowerShell):
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+El script analiza tu PC, descarga la Terminal, verifica su SHA-256 y la descomprime en tu carpeta personal. No necesita
+permisos de administrador. En Windows, abre una ventana de terminal nueva después. Luego arranca Strata:
+
+```sh
+strata launch
+```
+
+Te hace una pregunta cada vez: modelo, contexto, imágenes, quién puede conectarse. Después descarga el motor para tu tarjeta
+gráfica (firmado y arrancado como prueba antes de usarlo) y el modelo, y empieza a servir. Para scripts y agentes de IA, usa
+opciones:
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+Si quieres leer el script de instalación antes de ejecutarlo, descárgalo primero con `curl -fsSL <address> -o install.sh`,
+léelo y luego ejecuta `sh install.sh`. Todas las pantallas y opciones: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md).
+
+### Opción C: que lo instale tu IA
+
+Pega esto en Claude Code, Cursor, Codex, GitHub Copilot u otro asistente de programación:

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.

+El asistente revisa tu tarjeta gráfica, tu RAM y tu disco, elige el modelo adecuado, lo instala y lo arranca, y te explica
+cómo conectar tus aplicaciones. Las herramientas de IA también pueden instalar, arrancar y detener Strata mediante su
 [servidor MCP](docs/MCP_SERVER.md).

-### O hazlo tú mismo
+¿Prefieres compilarlo tú? Mira [Compilar desde el código fuente](#compilar-desde-el-código-fuente).

-[Descarga Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) y descomprímelo (o usa `git clone`).
-**Windows:** haz doble clic en **`START-HERE.bat`**. **Linux:** ejecuta **`./setup.sh`** en la carpeta de Strata.
+## Modelos

-Los pasos son los mismos para NVIDIA y AMD. El instalador detecta tu tarjeta y prepara el motor adecuado para ella.
-Te hace unas pocas preguntas:
+La aplicación y `strata launch` recomiendan un modelo según tu memoria. Es un solo modelo en varios tamaños, más o menos
+comprimido. Los tamaños pequeños son más rápidos. Los grandes son algo más inteligentes.

- qué modelo y qué tamaño,
- cuánto contexto (cuánto texto tiene presente el modelo),
- si debe entender imágenes.
+### ¿Poca memoria? Prueba Gyro

-Pulsa Enter cada vez para usar la respuesta recomendada. Después descarga el modelo (unos 70 GB) y lo arranca. Si la
-descarga se detiene, vuelve a ejecutarlo: sigue donde lo dejó. Tu navegador abre la aplicación de Strata en
-`http://127.0.0.1:8080`.
+[Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF) (de agentionai) es la forma más pequeña de ejecutar este modelo.

-> **Mientras el modelo arranca, tu PC puede ir lento o dejar de responder durante 1-3 minutos** (más la primera vez).
-> Strata carga 35-55 GB en tu RAM y reserva una parte para la tarjeta gráfica. Es normal. Espera y no cierres la
-> ventana. La ventana muestra lo que está haciendo Strata.
+| Tamaño | Memoria que necesita (RAM + VRAM) | Descarga | Qué es |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27,6 GB | 58,5 GB | Para PC donde no cabe nada más. La calidad es menor que la de IQ2_XS. |
+| **Gyro-M** | 35 GB | 92,0 GB | Calidad parecida a IQ3_XXS con un 20 % menos de memoria de GPU. Escribe las respuestas un 16 % más despacio que Q2_0 en una RTX 3060 de 12 GB y un 21 % más despacio en una R9700. |

-**La próxima vez**, vuelve a ejecutar `START-HERE.bat` (o `./setup.sh`). Arranca enseguida y no descarga nada dos
-veces. Cierra su ventana para detener el modelo. `UPDATE.bat` (`./update.sh`) actualiza Strata sin arrancarlo.
-Actualizaciones, Docker, varias tarjetas, dónde se guardan los archivos y todas las opciones: [docs/INSTALL.md](docs/INSTALL.md).
+Gyro funciona en tarjetas NVIDIA y AMD (en AMD es experimental) en tarjetas Intel Arc con Linux (probado en una Arc A750) y, desde 0.2.2, en Mac con Apple Silicon (Gyro-S en un Mac mini de 32 GB: 9 tokens/s, con los expertos leídos del SSD). Detalles y mediciones:
+[docs/GYRO.md](docs/GYRO.md). Arráncalo con `strata launch --model gyro-s`.

-## ¿Qué modelo elijo?
+### Los demás tamaños

-El instalador te recomienda uno según tu RAM. El mismo modelo viene en varios tamaños, más o menos comprimidos. Los
-tamaños pequeños son más rápidos. Los grandes son algo más inteligentes.
-
-| Tu RAM | Elige | Por qué |
+| Tu memoria (RAM + VRAM) | Elige | Notas |
 | --- | --- | --- |
-| **32 GB** | **Coder** | cabe en 32 GB y está hecho para programar (con una tarjeta de 24 GB también funcionan Q2_0 e IQ2_XS) |
-| **48 GB** | **IQ2_XS** (o Q2_0, el más rápido) | los tamaños más grandes no caben |
-| **64 GB** | **IQ2_XS** (recomendado), o IQ3_XXS / IQ3_S | caben todos los tamaños; IQ3_S es el mejor y el más lento |
-| **96 GB o más** | **IQ3_S**, o el UD-IQ4_XS de Unsloth (~4 bits) | espacio para los tamaños más grandes con todo lo demás abierto |
+| **32 GB** | **Gyro-S**, o el **[Coder](docs/MODELS.md#coder)** para código | El Coder necesita 32 GB de RAM y conserva la mitad de los expertos, así que es más flojo fuera del código |
+| **40 GB** | **[Swift 1.5](docs/MODELS.md#swift-15)** IQ2_XS (39,2 GB), o **Gyro-M** (35 GB) | Swift piensa menos tiempo antes de responder. Gyro-M se acerca a la calidad de IQ3_XXS, pero escribe las respuestas un 16-21 % más despacio que Q2_0 |
+| **48 GB** | **IQ3_XXS** (47,0 GB) | Más lento, mejor |
+| **64 GB** | **IQ3_S** (54,8 GB), el original o Swift 1.5 | El más lento, el mejor. Iguala al modelo completo en las pruebas publicadas |
+| **96 GB o más** | **UD-IQ4_XS** de Unsloth (unos 72 GB de RAM) hasta **Q8_0** (unos 136 GB), de 4 a 8 bits | Más cerca del modelo completo. Con menos RAM, Strata lee una parte desde el SSD, que es mucho más lento |

- **[Coder](docs/MODELS.md#coder):** una versión para programar a la que se le quitó la mitad de los expertos. Alcanza
-  el 91% de la puntuación SWE-bench Verified del modelo completo (medido por sus autores) y cabe en 32 GB de RAM. Es
-  más flojo fuera del código, también con chino y otros textos CJK (#438). Para eso, elige Q2_0, IQ2_XS o IQ3_S, que
-  conservan todos los expertos.
- **[Swift 1.5](docs/MODELS.md#swift-15):** un ajuste fino que piensa mucho menos tiempo antes de responder. Recibes
-  la respuesta antes, con más o menos la misma calidad.
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs):** la versión de ~4 bits de Unsloth, entre IQ3_S y
-  UD-Q4_K_XL en calidad. Una descarga de 94 GB. Con menos de ~80 GB de RAM, Strata lee una parte desde el SSD
-  mientras responde, así que ahí es más lento (un SSD NVMe ayuda).
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)** (experimental): el más parecido al modelo
-  completo. Pero Strata lee la mayor parte desde el SSD mientras responde, así que solo escribe 7-8.5 tokens/s en un
-  PC con 64 GB.
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs):** se instala a mano. No está en
-  el menú del instalador.
+Con menos RAM de la que indica una fila también puede funcionar: Strata pasa solo a su
+[modo de poca RAM](docs/MODELS.md#a-big-graphics-card-and-little-ram). Espera que sea más lento, y mucho más lento con una
+tarjeta gráfica pequeña.

-Tamaños, descargas y qué cabe dónde: [docs/MODELS.md](docs/MODELS.md). Para añadir otro modelo más adelante, ejecuta
-`SETUP.bat` (Linux: `./setup.sh --setup`).
+Más opciones:

-## Cómo usarlo
+- **[Swift 1.5](docs/MODELS.md#swift-15)** es un ajuste fino que piensa menos tiempo antes de responder, con una calidad y un uso de RAM casi iguales.
+- **[NVFP4](docs/NVFP4.md)** es la versión de 4 bits de NVIDIA para tarjetas NVIDIA. Necesita unos 80 GB de RAM para tener todos los expertos en RAM.

- **En el navegador:** abre `http://127.0.0.1:8080`. Tiene **Chat**, un **Monitor** en vivo del modelo y de tu
-  GPU/CPU/RAM, y **About** con los ajustes y las direcciones.
- **Tus aplicaciones y agentes de programación:** añade un proveedor "compatible con OpenAI" con la URL base
-  **`http://127.0.0.1:8080/v1`**. Sirve cualquier clave de API y cualquier nombre de modelo.
-  - Aplicaciones que usan la API de Anthropic: `http://127.0.0.1:8080/v1/messages` (Claude Code:

-  - Codex CLI y otras aplicaciones que usan la API Responses de OpenAI: `/v1/responses`
-    ([configuración](docs/DETAILS.md#the-responses-api-and-codex-cli)).
- **Razonamiento:** elige **off, low, medium o high** en el menú del chat o en el "reasoning effort" de tu aplicación.
-  Off es lo más rápido. High es lo mejor para preguntas difíciles.
- **Imágenes:** responde que sí a "Images?" en la instalación. Luego haz clic en **Picture** en el chat, o adjunta
-  imágenes en tu aplicación. Las tarjetas AMD leen imágenes en Linux a través del procesador; en Windows todavía no.
- **Desde tu móvil u otro PC:** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>`. Pon siempre una clave.
- **Una petición cada vez:** por defecto Strata responde una petición y las demás esperan. Para responder varias a la
-  vez, pon `"parallel": 2` ([BATCHING.md](docs/BATCHING.md)). En una tarjeta de 12 GB, cada respuesta va más lenta.
- **Prompts largos:** Strata lee entero el primer mensaje de un chat, más o menos 1 minuto por cada 30,000 tokens. Los
-  mensajes siguientes empiezan en segundos.

-  elige un tamaño más pequeño.
- **Se detuvo durante la descarga o la instalación.** Vuelve a ejecutar `START-HERE.bat` (o `./setup.sh`). Sigue
-  donde se detuvo.
- **Va muy lento y la luz del disco no deja de parpadear, o dice "the engine stopped unexpectedly".** Tu PC no tiene
-  suficiente RAM libre. Cierra otros programas (los navegadores usan mucha), o elige un tamaño más pequeño (Q2_0 o
-  IQ2_XS).
- **Dice que el puerto 8080 ya está en uso.** Strata ya está en marcha. Busca su ventana.

+
+| Modelo | Las respuestas aparecen a | Lee tu prompt a |
+| --- | --- | --- |
+| **Q2_0** | `████████████` 94 tokens/s | `████████████` 2.650 tokens/s |
+| **IQ2_XS** | `██████████░░` 79 tokens/s | `█████████░░░` 2.090 tokens/s |
+| **IQ3_XXS** | `████████░░░░` 62 tokens/s | `████████░░░░` 1.750 tokens/s |

+| **Coder** | `███████░░░░░` 55 tokens/s | `██████████░░` 2.180 tokens/s |
+
+Un token equivale a unos ¾ de palabra, así que 60 tokens por segundo es más rápido de lo que puedes leer. "Lee tu prompt"
+es lo rápido que Strata procesa un documento largo, código o un historial de chat.
+
+Medido con una tarjeta AMD de 16 GB (RX 9070 XT, Ryzen 9 3900X, 47 GB de RAM):
+

+| **Coder** | `██████░░░░░░` 44 tokens/s | `██████░░░░░░` 1.420 tokens/s |
+
+Las barras usan la misma escala en las dos tablas. Una tarjeta con más VRAM es más rápida. Una RTX 3090 (24 GB) debería
+escribir unos 100-140 tokens por segundo. La versión del motor detrás de cada cifra está en [DETAILS.md](docs/DETAILS.md#speed-measured).
+
+## Uso
+
+### En la aplicación
+
+La aplicación tiene un **Chat**, un **Monitor** del modelo y de tu GPU, CPU y RAM, una página de **Modelos** y los
+**Ajustes**. El chat puede trabajar en una carpeta de tu PC. En modo **Manual** pregunta antes de cambiar un archivo o
+ejecutar un comando. Escribe `/loop 10m <what to do>` para repetir un mensaje cada 10 minutos mientras el chat esté abierto.
+
+El chat puede buscar en la web con DuckDuckGo (o Bing), sin cuenta. Puedes añadir una clave de búsqueda en **Ajustes,
+Herramientas**. La búsqueda es la única función que envía algo fuera de tu PC (las palabras que buscas).
+
+Para ejecutar dos modelos, activa **Ejecutar varios modelos** y dale a cada modelo su propia tarjeta de la misma marca.

+```
+
+`strata --help` lo lista todo. Arrancar y servir no descargan nada. Solo lo hacen la instalación, `strata launch` (cuando
+eliges un modelo) y `strata update`. Para llegar a Strata desde tu móvil u otro PC, usa `strata launch --access lan`. Crea
+una clave de API y no arranca en una red sin ella. No se abre ningún navegador salvo que añadas `--open`. Guía:
+[docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md). El cliente completo: [docs/TERMINAL.md](docs/TERMINAL.md).
+
+### Con agentes de IA
+
+Un agente instala Strata con el comando de una línea de la opción B y ejecuta
+`strata launch --model NAME --yes --no-tui`. Los pasos, las opciones y los códigos de salida están en [docs/AI_SETUP.md](docs/AI_SETUP.md),
+y las reglas del repositorio en [AGENTS.md](AGENTS.md).
+
+### Conecta tus otras aplicaciones
+
+| Tipo de aplicación | URL base |
+| --- | --- |
+| Compatible con OpenAI (la mayoría de aplicaciones y agentes) | `http://127.0.0.1:8080/v1` (cualquier clave de API, cualquier nombre de modelo) |
+| API de Anthropic (Claude Code y otros) | `http://127.0.0.1:8080`, sin `/v1`. Estas aplicaciones añaden `/v1/messages` por su cuenta. Claude Code: `ANTHROPIC_BASE_URL=http://127.0.0.1:8080` |
+| API OpenAI Responses (Codex CLI) | `http://127.0.0.1:8080/v1/responses` ([configuración](docs/DETAILS.md#the-responses-api-and-codex-cli)) |
+
+`strata connect` muestra los ajustes exactos para OpenCode, Codex CLI, Claude Code, oh-my-pi, pi, Hermes Agent y OpenClaw.
+`strata connect opencode --write` escribe el archivo después de preguntar y guarda una copia de seguridad.
+
+### Imágenes
+
+Las imágenes vienen activadas por defecto en los modelos que pueden leerlas. Adjunta o pega una imagen en el chat, o envíala
+desde tu aplicación. El lector de imágenes funciona en el procesador cuando tu tarjeta gráfica tiene menos de 24 GB (unos
+segundos por imagen, sin quitar memoria a la tarjeta) y en la tarjeta gráfica a partir de 24 GB. La regla es la misma para
+NVIDIA y AMD. Puedes desactivar las imágenes por modelo, o elegir el lector con `--vision off`, `--vision gpu` o
+`--vision cpu`.
+
+Las cifras detrás de la regla: en una Radeon AI PRO R9700, el lector de la tarjeta tardó 57 ms en una imagen de 260 tokens y
+el del procesador 3,1 s. En tarjetas de 16 GB (Tesla P100 y RTX A4000, Linux), el lector de la tarjeta costó un 3-5 % de
+velocidad en texto, porque ocupa unos 1,4 GB que de otro modo usaría el modelo. En un Mac lee la GPU, tenga la memoria que tenga (0,45 s para una imagen de 260 tokens en un M4 de 32 GB, unos 1,2 GB de la memoria compartida);
+el procesador tarda unos 50 s por imagen, así que solo lee con `--vision cpu`.
+
+### Conviene saber
+
+- Elige el nivel de razonamiento (**desactivado, bajo, medio o alto**) en el menú del chat o en "reasoning effort" de tu aplicación. Desactivado es lo más rápido.
+- Strata responde a una petición a la vez por defecto. Para varias a la vez, usa `--parallel N` en `strata launch` o
+  `"parallel": 2` en la configuración ([BATCHING.md](docs/BATCHING.md)). En una tarjeta de 12 GB, esto hace más lenta cada respuesta.
+- Strata lee entero el primer mensaje de un chat, unos 1 minuto por cada 30.000 tokens. Los mensajes siguientes empiezan en segundos.

+## Compilar desde el código fuente
+
+<details>
+<summary>Windows, Linux y Mac desde el repositorio</summary>
+
+[Descarga Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) y descomprímelo, o haz `git clone`.
+**Windows:** haz doble clic en `START-HERE.bat`. **Linux:** ejecuta `./setup.sh` en la carpeta de Strata.
+
+**Mac (Apple Silicon, macOS 15 o posterior):** instala una vez las Command Line Tools de Apple con `xcode-select --install`
+(no hace falta Xcode). Abre la Terminal en la carpeta de Strata y ejecuta `./setup.sh`. El script compila el motor para Mac
+en tu Mac (unos 7 minutos), hace las mismas preguntas, descarga el modelo y lo arranca. La próxima vez, `./setup.sh` lo
+arranca enseguida. Qué tamaño cabe en tu Mac: [docs/MAC.md](docs/MAC.md).
+
+El instalador detecta tu tarjeta y prepara el motor adecuado. Pregunta qué modelo y qué tamaño quieres, cuánto contexto
+(cuánto texto mantiene el modelo en mente) y si debe leer imágenes. Pulsa Enter para aceptar la respuesta recomendada.
+Luego descarga el modelo (unos 70 GB) y lo arranca. Si la descarga se detiene, vuelve a ejecutar el script y continúa. Tu
+navegador abre la página de Strata en `http://127.0.0.1:8080`.
+
+> Mientras el modelo arranca, tu PC puede ir lento o dejar de responder durante 1-3 minutos (más tiempo la primera vez).
+> Strata carga 35-55 GB en tu RAM y bloquea una parte para la tarjeta gráfica. Espera y no cierres la ventana.
+
+La próxima vez, ejecuta de nuevo `START-HERE.bat` (o `./setup.sh`). Arranca enseguida y no descarga nada dos veces. Cierra
+su ventana para detener el modelo. `UPDATE.bat` (`./update.sh`) actualiza Strata sin arrancarlo. Actualización, Docker,
+varias tarjetas, dónde van los archivos y todas las opciones: [docs/INSTALL.md](docs/INSTALL.md).
+
+Para medir tu PC, ejecuta `BENCH.bat` (`./bench.sh`). Tarda 5-10 minutos y escribe un informe que puedes compartir
+([cómo](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)).
+
+**Opcional: más velocidad en una tarjeta cuando todo el modelo cabe en la RAM.** Dos ajustes que se activan a mano, de
+RubenTorney (#1904, #1905). Ayudan cuando usas una sola tarjeta gráfica y tu RAM guarda todos los expertos, por ejemplo con
+Q2_0 o IQ3_XXS en un PC de 64 GB. Abre `strata-<model>.json` en la carpeta de datos de Strata ([dónde](docs/INSTALL.md#where-things-are-stored)) y añade:
+
+- `"--adapt-async", "1"` a la lista `"args"`. Así la caché de expertos se actualiza en un hilo auxiliar en vez de detener la
+  respuesta. Medido en una RTX 5070 (Windows, Q2_0): +4-5 % en decodificación, +7-10 % en código y documentos largos. Las
+  respuestas pueden diferir un poco de las del ajuste por defecto y son iguales de una ejecución a otra.
+- `"STRATA_PIN_BY_NEED": "1"` en el bloque `"env"` (Windows). Windows solo puede bloquear aproximadamente la mitad de la RAM
+  para la tarjeta gráfica, y este ajuste bloquea primero los expertos que la tarjeta necesita antes. Medido en la RTX 5070: +4,4 % en lectura del prompt.
+
+```json
+"args": [ ..., "--adapt-async", "1" ],
+"env": { "STRATA_PIN_BY_NEED": "1" }
+```
+
+Reinicia Strata después del cambio. Para deshacerlo, quita las dos entradas.

+**Il vous faut au moins 32 Go de RAM et de mémoire graphique (VRAM) réunis.** Sur un Mac ou un Ryzen AI Max, c'est la
+mémoire unifiée. Plus de mémoire permet un modèle plus gros ou plus rapide.
+
+- Un PC de 32 Go avec une carte de 12 à 16 Go fait tourner le Coder.
+- Avec 64 Go de RAM, toutes les tailles fonctionnent.
+
+| Votre ordinateur | Détails |
 | --- | --- |
-| **Carte graphique** | **NVIDIA** GeForce RTX série 20, 30, 40 ou 50, ou **AMD** Radeon RX 7900 XT / XTX, RX 7800 XT / 7700 XT, RX 9060 XT, RX 9070 / 9070 XT, Radeon AI PRO R9700 ou série RX 6800 / 6900. Il faut **12 Go de VRAM ou plus**. |
-| **RAM** | 32 Go ou plus. Votre RAM décide [quel modèle](#quel-modèle-choisir-) tient. Avec 64 Go, toutes les tailles tournent. |
-| **Disque** | Environ 80 Go libres. Prenez un SSD si possible : le premier démarrage est bien plus rapide. |
-| **Système** | Windows 10 / 11 ou Linux, avec un pilote graphique NVIDIA ou AMD à jour. |
+| **NVIDIA** GeForce RTX série 20, 30, 40, 50 (12 Go ou plus) | Installez l'application ou le Terminal. |
+| **AMD** Radeon RX 6800 et plus récent, Radeon AI PRO R9700 (12 Go ou plus) | [Cartes AMD](docs/AMD_HIP.md) |
+| **Intel** Arc | [Intel Arc](docs/INTEL_ARC.md), [moteur Intel](docs/INTEL.md) |
+| **Mac Apple Silicon** (M1 ou plus récent, macOS 15 ou plus récent) | [Mac](docs/MAC.md) |
+| **AMD Ryzen AI Max (Strix Halo)** et autres systèmes à mémoire unifiée | [Strix Halo](docs/STRIX_HALO.md) |
+| Cartes et processeurs plus anciens | [GPU anciens](docs/OLDER_GPUS.md), [CPU anciens](docs/INSTALL.md#older-cpus-experimental) |

-L'installateur s'occupe de tout le reste. Deux ou trois cartes peuvent se partager le modèle ([multi-GPU](docs/MULTI_GPU.md)).
+Il faut aussi :

-Expérimental, écrit et testé par des membres de la communauté sur leurs propres machines :
+- environ 80 Go d'espace disque libre (un SSD accélère beaucoup le premier démarrage)
+- Windows 10 / 11, Linux ou macOS
+- un pilote graphique récent

- **Cartes graphiques plus anciennes** (Tesla P40 / V100, GTX 10, Radeon VII / MI50, RX 6700 XT, RX 5500 XT) : [Older GPUs](docs/OLDER_GPUS.md).
- **Intel Arc**, compilé depuis les sources sous Linux : [Intel Arc](docs/INTEL_ARC.md).
- **AMD Ryzen AI Max (Strix Halo)**, compilé depuis les sources sous Linux : [Strix Halo](docs/STRIX_HALO.md).
- **Processeurs plus anciens sans AVX2** : ça marche, mais lentement. [Older CPUs](docs/INSTALL.md#older-cpus-experimental).
-
-La liste complète : [docs/INSTALL.md](docs/INSTALL.md#what-you-need).
+Deux ou trois cartes de la même marque peuvent se partager un modèle ([multi-GPU](docs/MULTI_GPU.md)). Strata ne répartit
+jamais un modèle entre des cartes NVIDIA et AMD. Liste complète : [docs/INSTALL.md](docs/INSTALL.md#what-you-need).

 ## Installation

-### Laissez votre IA l'installer
+Choisissez une option. Elles lancent toutes le même moteur et utilisent les mêmes modèles.

-Vous utilisez un assistant de code IA (Claude Code, Cursor, Codex, GitHub Copilot, ...) ? Collez-lui ceci :
+### Option A : l'application Strata
+
+Le plus simple. L'application contient le moteur : installez-la, choisissez un modèle, discutez. Téléchargez le fichier
+correspondant à votre système et à votre carte graphique depuis la [page des versions](https://github.com/Niko1221/Strata/releases/latest).
+Vous ne savez pas lequel prendre ? Lisez le paragraphe sous le tableau.
+
+| Système | Votre carte graphique | Fichier à télécharger |
+| --- | --- | --- |
+| **Windows 10 / 11** | NVIDIA RTX, pilote 580 ou plus récent | [`Strata-0.2.3-windows-cuda13.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda13.exe) |
+| | NVIDIA, carte plus ancienne ou pilote antérieur à 580 | [`Strata-0.2.3-windows-cuda12.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda12.exe) |
+| | AMD Radeon série RX 9000 ou Radeon AI PRO R9700 | [`Strata-0.2.3-windows-hip.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip.exe) |
+| | AMD Radeon série RX 7000 ou Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-windows-hip-rdna3.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip-rdna3.exe) |
+| **Linux** | NVIDIA RTX, pilote 580 ou plus récent | [`Strata-0.2.3-linux-nvidia-cuda13.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda13.AppImage) |
+| | NVIDIA, carte plus ancienne ou pilote antérieur à 580 | [`Strata-0.2.3-linux-nvidia-cuda12.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda12.AppImage) |
+| | AMD Radeon série RX 9000 ou Radeon AI PRO R9700 | [`Strata-0.2.3-linux-amd-rx9070.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx9070.AppImage) |
+| | AMD Radeon série RX 7000 | [`Strata-0.2.3-linux-amd-rx7900.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx7900.AppImage) |
+| | AMD Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-linux-amd-strixhalo.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-strixhalo.AppImage) |
+| **Mac** (Apple Silicon, macOS 15 ou plus récent) | intégrée | [`Strata-0.2.3-mac.dmg`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-mac.dmg) |
+
+**Si vous hésitez :** pour NVIDIA, prenez `cuda13` si la version de votre pilote est 580 ou plus récente, sinon `cuda12`.
+`cuda12` convient aux cartes plus anciennes et aux pilotes plus anciens. Les fichiers `hip` et `amd` sont pour les cartes
+AMD. Les autres cartes AMD (RX 6000) n'ont pas encore d'application prête à l'emploi : voir
+[Cartes AMD](docs/AMD_HIP.md).
+
+Ensuite :
+
+- **Windows :** lancez le `.exe`. Il s'installe pour votre utilisateur et ne demande pas de droits d'administrateur. Si
+  Windows affiche « Windows a protégé votre ordinateur », choisissez **Informations complémentaires**, puis **Exécuter
+  quand même** (l'installateur n'est pas encore signé).
+- **Linux :** rendez le fichier exécutable (`chmod +x`) et lancez-le. Il a besoin de FUSE 2 : `sudo apt install libfuse2`
+  (Ubuntu 22.04) ou `libfuse2t64` (Ubuntu 24.04 et plus récent).
+- **Mac :** ouvrez le `.dmg` et faites glisser Strata dans Applications.
+
+Sur le premier écran, l'application analyse votre PC et recommande un modèle adapté. Appuyez sur Installer. Le modèle est un
+gros téléchargement (environ 40 à 70 Go) qui reprend là où il s'est arrêté en cas d'interruption. Quand vous fermez la
+fenêtre, Strata et le moteur s'arrêtent.
+
+### Option B : le Terminal (une ligne)
+
+Le Terminal est la commande `strata`, pensée pour les scripts, les serveurs et les agents d'IA.
+
+Linux et Mac :
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows (PowerShell) :
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+Le script analyse votre PC, télécharge le Terminal, vérifie son empreinte SHA-256 et le décompresse dans votre dossier
+personnel. Il ne demande pas de droits d'administrateur. Sous Windows, ouvrez ensuite une nouvelle fenêtre de terminal.
+Puis lancez Strata :
+
+```sh
+strata launch
+```
+
+Il pose une question à la fois : modèle, contexte, images, qui peut se connecter. Ensuite il télécharge le moteur pour votre
+carte graphique (signé, et lancé à titre d'essai avant usage) ainsi que le modèle, puis commence à servir. Pour les scripts
+et les agents d'IA, utilisez des options :
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+Pour lire le script d'installation avant de l'exécuter, téléchargez-le d'abord avec `curl -fsSL <address> -o install.sh`,
+lisez-le, puis lancez `sh install.sh`. Tous les écrans et toutes les options : [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md).
+
+### Option C : laissez votre IA l'installer
+
+Collez ceci dans Claude Code, Cursor, Codex, GitHub Copilot ou un autre assistant de programmation :

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.
 ```

-Il vérifie votre carte graphique, votre RAM et votre disque, et choisit le modèle qui convient. Ensuite il l'installe,
-le démarre et vous explique comment connecter vos applications. Les outils d'IA peuvent aussi installer, démarrer et
-arrêter Strata grâce à son [serveur MCP](docs/MCP_SERVER.md).
+L'assistant vérifie votre carte graphique, votre RAM et votre disque, choisit le modèle adapté, l'installe, le démarre et
+vous explique comment connecter vos applications. Les outils d'IA peuvent aussi installer, démarrer et arrêter Strata via son
+[serveur MCP](docs/MCP_SERVER.md).

-### Ou faites-le vous-même
+Vous préférez le compiler vous-même ? Voir [Compiler depuis les sources](#compiler-depuis-les-sources).

-[Téléchargez Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) et décompressez-le (ou faites un `git clone`).
-**Windows :** double-cliquez sur **`START-HERE.bat`**. **Linux :** lancez **`./setup.sh`** dans le dossier Strata.
+## Modèles

-Les étapes sont les mêmes pour NVIDIA et AMD. L'installateur détecte votre carte et installe le bon moteur pour elle.
-Il vous pose quelques questions :
+L'application et `strata launch` recommandent un modèle selon votre mémoire. C'est un seul modèle en plusieurs tailles,
+plus ou moins compressé. Les petites tailles sont plus rapides. Les grandes sont un peu plus intelligentes.

- quel modèle et quelle taille,
- combien de contexte (la quantité de texte que le modèle garde en tête),
- s'il doit lire les images.
+### Peu de mémoire ? Essayez Gyro

-Appuyez sur Entrée à chaque fois pour garder la réponse recommandée. Ensuite il télécharge le modèle (environ 70 Go)
-et le démarre. Si le téléchargement s'arrête, relancez-le : il reprend là où il s'était arrêté. Votre navigateur
-ouvre l'application Strata à l'adresse `http://127.0.0.1:8080`.
+[Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF) (par agentionai) est la façon la plus légère de faire tourner ce modèle.

-> **Pendant le démarrage du modèle, votre PC peut ralentir ou ne plus répondre pendant 1-3 minutes** (plus longtemps la première fois).
-> Strata charge 35-55 Go dans votre RAM et en réserve une partie pour la carte graphique. C'est normal. Attendez, et
-> ne fermez pas la fenêtre. La fenêtre montre ce que fait Strata.
+| Taille | Mémoire nécessaire (RAM + VRAM) | Téléchargement | Ce que c'est |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27,6 Go | 58,5 Go | Pour les PC où rien d'autre ne tient. La qualité est inférieure à celle d'IQ2_XS. |
+| **Gyro-M** | 35 Go | 92,0 Go | À peu près la qualité d'IQ3_XXS avec environ 20 % de mémoire GPU en moins. Il écrit les réponses 16 % plus lentement que Q2_0 sur une RTX 3060 de 12 Go et 21 % plus lentement sur une R9700. |

-**La fois suivante**, relancez `START-HERE.bat` (ou `./setup.sh`). Il démarre tout de suite et ne télécharge rien
-deux fois. Fermez sa fenêtre pour arrêter le modèle. `UPDATE.bat` (`./update.sh`) met Strata à jour sans le démarrer.
-Mises à jour, Docker, plusieurs cartes, emplacement des fichiers et toutes les options : [docs/INSTALL.md](docs/INSTALL.md).
+Gyro fonctionne sur les cartes NVIDIA et AMD (expérimental sur AMD) sur les cartes Intel Arc sous Linux (testé sur une Arc A750) et, depuis la 0.2.2, sur les Mac Apple Silicon (Gyro-S sur un Mac mini de 32 Go : 9 tokens/s, experts lus sur le SSD). Détails et mesures :
+[docs/GYRO.md](docs/GYRO.md). Lancez-le avec `strata launch --model gyro-s`.

-## Quel modèle choisir ?
+### Les autres tailles

-L'installateur en recommande un selon votre RAM. Le même modèle existe en plusieurs tailles, plus ou moins
-compressées. Les petites tailles sont plus rapides. Les grandes sont un peu plus intelligentes.
-
-| Votre RAM | Prenez | Pourquoi |
+| Votre mémoire (RAM + VRAM) | Prenez | Remarques |
 | --- | --- | --- |
-| **32 Go** | **Coder** | il tient dans 32 Go et il est fait pour le code (avec une carte de 24 Go, Q2_0 et IQ2_XS tournent aussi) |
-| **48 Go** | **IQ2_XS** (ou Q2_0, le plus rapide) | les plus grandes tailles ne tiennent pas |
-| **64 Go** | **IQ2_XS** (recommandé), ou IQ3_XXS / IQ3_S | toutes les tailles tiennent ; IQ3_S est le meilleur et le plus lent |
-| **96 Go ou plus** | **IQ3_S**, ou l'UD-IQ4_XS d'Unsloth (~4 bits) | de la place pour les plus grandes tailles, avec tout le reste ouvert |
+| **32 Go** | **Gyro-S**, ou le **[Coder](docs/MODELS.md#coder)** pour le code | Le Coder demande 32 Go de RAM et garde la moitié des experts, il est donc moins bon hors du code |
+| **40 Go** | **[Swift 1.5](docs/MODELS.md#swift-15)** IQ2_XS (39,2 Go), ou **Gyro-M** (35 Go) | Swift réfléchit moins longtemps avant de répondre. Gyro-M approche la qualité d'IQ3_XXS, mais il écrit les réponses 16 à 21 % plus lentement que Q2_0 |
+| **48 Go** | **IQ3_XXS** (47,0 Go) | Plus lent, meilleur |
+| **64 Go** | **IQ3_S** (54,8 Go), l'original ou Swift 1.5 | Le plus lent, le meilleur. Il égale le modèle complet dans les tests publiés |
+| **96 Go ou plus** | **UD-IQ4_XS** d'Unsloth (environ 72 Go de RAM) jusqu'à **Q8_0** (environ 136 Go), 4 à 8 bits | Plus proche du modèle complet. Avec moins de RAM, Strata lit une partie depuis le SSD, ce qui est beaucoup plus lent |

- **[Coder](docs/MODELS.md#coder) :** une version pour le code, avec la moitié des experts en moins. Elle atteint 91 %
-  du score SWE-bench Verified du modèle complet (mesuré par ses auteurs) et tient dans 32 Go de RAM. Elle est moins
-  bonne en dehors du code, y compris pour le chinois et les autres textes CJK (#438). Pour ces cas, prenez Q2_0,
-  IQ2_XS ou IQ3_S, qui gardent tous les experts.
- **[Swift 1.5](docs/MODELS.md#swift-15) :** un fine-tune qui réfléchit bien moins longtemps avant de répondre. Vous
-  avez la réponse plus tôt, avec à peu près la même qualité.
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs)** : la version ~4 bits d'Unsloth, entre IQ3_S et
-  UD-Q4_K_XL en qualité. Un téléchargement de 94 Go. Avec moins de ~80 Go de RAM, Strata en lit une partie depuis
-  le SSD pendant qu'il répond, il y est donc plus lent (un SSD NVMe aide).
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)** (expérimental) : le plus proche du modèle
-  complet. Mais Strata en lit la plus grande partie depuis le SSD pendant qu'il répond, donc il n'écrit que
-  7-8.5 tokens/s sur un PC avec 64 Go.
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs) :** vous l'installez à la main.
-  Il n'est pas dans le menu de l'installateur.
+Avoir moins de RAM que ce qu'indique une ligne peut encore fonctionner : Strata passe tout seul en
+[mode peu de RAM](docs/MODELS.md#a-big-graphics-card-and-little-ram). Attendez-vous à plus de lenteur, et à bien plus avec
+une petite carte graphique.

-Tailles, téléchargements et ce qui tient où : [docs/MODELS.md](docs/MODELS.md). Pour ajouter un autre modèle plus
-tard, lancez `SETUP.bat` (Linux : `./setup.sh --setup`).
+Autres choix :
+
+- **[Swift 1.5](docs/MODELS.md#swift-15)** est une version affinée qui réfléchit moins longtemps avant de répondre, pour une qualité et un besoin en RAM à peu près identiques.
+- **[NVFP4](docs/NVFP4.md)** est la version 4 bits de NVIDIA pour les cartes NVIDIA. Elle demande environ 80 Go de RAM pour garder tous les experts en RAM.
+- **[Qwen3.6-35B-A3B](docs/QWEN36.md)** est un modèle plus petit et différent, qui lit les images et peut répondre à plusieurs requêtes à la fois.
+- **[L'Uncensored IQ3_XXS d'OrcaRouter](docs/MODELS.md#orcarouter-uncensored-iq3_xxs)** se configure à la main.
+
+Toutes les tailles, les téléchargements et ce qui tient où : [docs/MODELS.md](docs/MODELS.md).
+
+### DeepSeek V4.1-Flash (dans le Terminal, depuis 0.2.4)
+
+[DeepSeek V4.1-Flash](https://huggingface.co/ISTA-DASLab/DeepSeek-V4.1-Flash-1017-GSQ-RCO-GGUF) est un autre modèle, beaucoup plus gros. ISTA-DASLab a produit les trois versions ci-dessous. Strata les fait tourner sur un PC avec une carte graphique de 12 Go et de 46 à 64 Go de RAM, et lit le reste sur votre SSD. Il fonctionne sur les cartes NVIDIA RTX des séries 30 à 50 et sur la Radeon AI PRO R9700. Il utilise son propre paquet de moteur, `strata-dsv41`, que `strata launch` télécharge quand vous choisissez DeepSeek. L’application de bureau ne le propose pas encore.
+
+| Version | Téléchargement | Qualité par rapport au modèle d’origine | Écrit à |
+| --- | ---: | --- | --- |
+| **IQ1_M** (1,75 bit) | 239 Go | KL 0,217, perplexité 3,80 (+21 %) ; code +8,9 %, tâches d’agent +10,2 % ; plus faible sur la prose anglaise courante. D’après la fiche du modèle d’ISTA-DASLab, elle garde 98,7 % de la moyenne des tâches du modèle de base (AIME25, GPQA-Diamond, LiveCodeBench v6). | pas encore mesurée |
+| **IQ2_XXS** (2.00 bits) | 257 GB | KL 0,170, perplexité 3,63 (+15,5 %) ; code +8,6 %, tâches d’agent +5,3 % | 6 à 9 tokens/s sur une RTX 3060, environ 5 sur une RTX 5070 |
+| **IQ2_XS** (2.25 bits) | 274 GB | KL 0,107, perplexité 3,37 (+7,3 %) ; code +3,2 %, tâches d’agent +2,2 % | environ 11 tokens/s sur une Radeon AI PRO R9700 |
+| **IQ4_NL** (table Engram, pas un troisième modèle) | 111 Go, déjà compris dans les trois téléchargements ci-dessus | La table de consultation Engram en 4 bits que le modèle lit dans la RAM ou sur le SSD. Les trois versions utilisent ce seul fichier (`DeepSeek-V4.1-Flash-Engram-IQ4_NL.gguf`). | n/a |
+
+4x Radeon AI PRO R9700 : environ 31 tokens/s, 55 à 69 avec DSpark.
+
+Lancez-le avec `strata launch --model ist-das-2.00bpw` (ou `ist-das-1.75bpw`, `ist-das-2.25bpw`). Détails, vitesses par carte et installation manuelle : [docs/DEEPSEEK41.md](docs/DEEPSEEK41.md).
+
+## Quelle est sa vitesse ?
+
+Mesuré avec une carte graphique de 12 Go (RTX 5070, Ryzen 5 7600, 64 Go de RAM). Voir les résultats d'autres cartes :
+[vitesse de chaque taille](docs/MODELS.md#how-fast-is-each-size), [résultats de la communauté](docs/COMMUNITY_BENCHMARKS.md).
+
+| Modèle | Les réponses s'affichent à | Lit votre prompt à |
+| --- | --- | --- |
+| **Q2_0** | `████████████` 94 tokens/s | `████████████` 2 650 tokens/s |
+| **IQ2_XS** | `██████████░░` 79 tokens/s | `█████████░░░` 2 090 tokens/s |
+| **IQ3_XXS** | `████████░░░░` 62 tokens/s | `████████░░░░` 1 750 tokens/s |
+| **IQ3_S** | `███████░░░░░` 53 tokens/s | `███████░░░░░` 1 620 tokens/s |
+| **Coder** | `███████░░░░░` 55 tokens/s | `██████████░░` 2 180 tokens/s |
+
+Un token vaut environ ¾ de mot, donc 60 tokens par seconde, c'est plus rapide que votre lecture. « Lit votre prompt »
+indique la vitesse à laquelle Strata absorbe un long document, du code ou un historique de discussion.
+
+Mesuré avec une carte AMD de 16 Go (RX 9070 XT, Ryzen 9 3900X, 47 Go de RAM) :
+
+| Modèle | Les réponses s'affichent à | Lit votre prompt à |
+| --- | --- | --- |
+| **Q2_0** | `████████░░░░` 60 tokens/s | `█████░░░░░░░` 1 160 tokens/s |
+| **IQ2_XS** | `███████░░░░░` 52 tokens/s | `█████░░░░░░░` 1 110 tokens/s |
+| **Coder** | `██████░░░░░░` 44 tokens/s | `██████░░░░░░` 1 420 tokens/s |
+
+Les barres utilisent la même échelle dans les deux tableaux. Une carte avec plus de VRAM est plus rapide. Une RTX 3090
+(24 Go) devrait écrire environ 100 à 140 tokens par seconde. La version du moteur derrière chaque chiffre est indiquée dans
+[DETAILS.md](docs/DETAILS.md#speed-measured).

 ## Utilisation

-<p align="center"><img src="docs/media/runpagoda.png" width="900" alt="L'onglet Monitor de l'application Strata à côté d'un agent de code"><br>
-<sub>Le <b>Monitor</b> de l'application Strata (à gauche) pendant qu'un agent de code écrit le jardin de pagode de la vidéo (à droite)</sub></p>
+### Dans l'application

- **Dans le navigateur :** ouvrez `http://127.0.0.1:8080`. Vous y trouvez **Chat**, un **Monitor** en direct du
-  modèle et de votre GPU/CPU/RAM, et **About** avec les réglages et les adresses.
- **Vos applications et agents de code :** ajoutez un fournisseur « OpenAI-compatible » avec l'URL de base
-  **`http://127.0.0.1:8080/v1`**. N'importe quelle clé API et n'importe quel nom de modèle fonctionnent.
-  - Applications qui utilisent l'API d'Anthropic : `http://127.0.0.1:8080/v1/messages` (Claude Code :
-    `ANTHROPIC_BASE_URL=http://127.0.0.1:8080`).
-  - Codex CLI et les autres applications qui utilisent l'API OpenAI Responses : `/v1/responses`
-    ([configuration](docs/DETAILS.md#the-responses-api-and-codex-cli)).
- **Réflexion :** choisissez **off, low, medium ou high** dans le menu du chat ou dans le « reasoning effort » de
-  votre application. Off est le plus rapide. High est le meilleur pour les questions difficiles.
- **Images :** répondez oui à « Images? » pendant l'installation. Ensuite cliquez sur **Picture** dans le chat, ou
-  joignez des images dans votre application. Les cartes AMD lisent les images sous Linux via le processeur ; sous
-  Windows, pas encore.
- **Depuis votre téléphone ou un autre PC :** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>`. Définissez
-  toujours une clé.
- **Une requête à la fois :** par défaut, Strata répond à une requête et les autres attendent. Pour répondre à
-  plusieurs en même temps, mettez `"parallel": 2` ([BATCHING.md](docs/BATCHING.md)). Sur une carte de 12 Go, chaque
-  réponse devient alors plus lente.
- **Longs prompts :** Strata lit en entier le premier message d'une discussion, environ 1 minute pour 30,000 tokens.
-  Les messages suivants démarrent en quelques secondes.
+L'application comprend un **Chat**, un **Monitor** du modèle, de votre GPU, de votre CPU et de votre RAM, une page **Models** et les **Settings**. Le chat peut travailler dans un dossier de votre PC. En mode **Manual**, il demande
+avant de modifier un fichier ou d'exécuter une commande. Tapez `/loop 10m <what to do>` pour répéter un message toutes les
+10 minutes tant que le chat est ouvert.

-Plus d'infos : [où sont stockées vos discussions](docs/INSTALL.md#where-things-are-stored), [l'API](docs/DETAILS.md#using-it).
+Le chat peut chercher sur le web avec DuckDuckGo (ou Bing), sans compte. Vous pouvez ajouter une clé de recherche sous
+**Settings, Tools**. La recherche est la seule fonction qui envoie quelque chose hors de votre PC (les mots recherchés).

-## Un problème ?
+Pour faire tourner deux modèles, activez **Run multiple models** (exécuter plusieurs modèles) et donnez à chacun sa propre carte de la même marque.

- **Mon PC s'est figé au premier démarrage de Strata.** C'est normal pendant le chargement du modèle. Attendez, et ne
-  fermez pas la fenêtre. Toujours figé après 10 minutes ? Redémarrez le PC, fermez les autres programmes et
-  réessayez, ou choisissez une taille plus petite.
- **Il s'est arrêté pendant le téléchargement ou l'installation.** Relancez `START-HERE.bat` (ou `./setup.sh`). Il
-  reprend là où il s'était arrêté.
- **C'est très lent et le voyant du disque clignote sans arrêt, ou il affiche « the engine stopped unexpectedly ».**
-  Votre PC n'a pas assez de RAM libre. Fermez les autres programmes (les navigateurs en utilisent beaucoup), ou
-  choisissez une taille plus petite (Q2_0 ou IQ2_XS).
- **Il dit que le port 8080 est déjà utilisé.** Strata tourne déjà. Cherchez sa fenêtre.

+
+`strata --help` liste tout. Démarrer et servir ne téléchargent rien. Seuls l'installation, `strata launch` (quand vous
+choisissez un modèle) et `strata update` le font. Pour joindre Strata depuis votre téléphone ou un autre PC, utilisez
+`strata launch --access lan`. La commande crée une clé d'API et refuse de démarrer sur un réseau sans elle. Aucun
+navigateur ne s'ouvre, sauf si vous ajoutez `--open`. Guide : [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md). Le client complet : [docs/TERMINAL.md](docs/TERMINAL.md).
+
+### Avec des agents d'IA
+
+Un agent installe Strata avec la commande en une ligne de l'option B et lance
+`strata launch --model NAME --yes --no-tui`. Les étapes, les options et les codes de sortie sont dans [docs/AI_SETUP.md](docs/AI_SETUP.md),
+et les règles du dépôt dans [AGENTS.md](AGENTS.md).

+| Compatible OpenAI (la plupart des applications et des agents) | `http://127.0.0.1:8080/v1` (n'importe quelle clé d'API, n'importe quel nom de modèle) |
+| API Anthropic (Claude Code et d'autres) | `http://127.0.0.1:8080`, sans `/v1`. Ces applications ajoutent `/v1/messages` elles-mêmes. Claude Code : `ANTHROPIC_BASE_URL=http://127.0.0.1:8080` |
+| API OpenAI Responses (Codex CLI) | `http://127.0.0.1:8080/v1/responses` ([configuration](docs/DETAILS.md#the-responses-api-and-codex-cli)) |

+`strata connect` affiche les réglages exacts pour OpenCode, Codex CLI, Claude Code, oh-my-pi, pi, Hermes Agent et OpenClaw.
+`strata connect opencode --write` écrit le fichier après confirmation et garde une sauvegarde.
+
+### Images
+
+Les images sont activées par défaut pour les modèles qui savent les lire. Joignez ou collez une image dans le chat, ou
+envoyez-la depuis votre application. Le lecteur d'images tourne sur le processeur quand votre carte graphique a moins de
+24 Go (quelques secondes par image, sans prendre de mémoire à la carte) et sur la carte graphique à partir de 24 Go. La
+règle est la même pour NVIDIA et AMD. Vous pouvez désactiver les images par modèle, ou choisir le lecteur avec
+`--vision off`, `--vision gpu` ou `--vision cpu`.
+
+Les chiffres derrière la règle : sur une Radeon AI PRO R9700, le lecteur de la carte a pris 57 ms pour une image de
+260 tokens et celui du processeur 3,1 s. Sur des cartes de 16 Go (Tesla P100 et RTX A4000, Linux), le lecteur de la carte
+a coûté 3 à 5 % de vitesse sur le texte, parce qu'il occupe environ 1,4 Go que le modèle utiliserait sinon. Sur un Mac, le lecteur tourne sur le GPU quelle que soit la mémoire (0,45 s pour une image de 260 tokens sur un M4 de 32 Go, environ 1,2 Go de la
+mémoire partagée) ; le processeur met environ 50 s par image, il ne lit donc qu'avec `--vision cpu`.
+
+### Bon à savoir
+
+- Choisissez le niveau de réflexion (**désactivé, faible, moyen ou élevé**) dans le menu du chat ou dans le réglage « reasoning effort » de votre application. Désactivé est le plus rapide.
+- Strata répond à une requête à la fois par défaut. Pour en traiter plusieurs en même temps, utilisez `--parallel N` dans `strata launch` ou
+  `"parallel": 2` dans la configuration ([BATCHING.md](docs/BATCHING.md)). Sur une carte de 12 Go, chaque réponse devient alors plus lente.
+- Strata lit en entier le premier message d'une discussion, soit environ 1 minute pour 30 000 tokens. Les messages suivants démarrent en quelques secondes.

+## Compiler depuis les sources
+
+<details>
+<summary>Windows, Linux et Mac depuis le dépôt</summary>
+
+[Téléchargez Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) et décompressez-le, ou faites un `git clone`.
+**Windows :** double-cliquez sur `START-HERE.bat`. **Linux :** lancez `./setup.sh` dans le dossier Strata.
+
+**Mac (Apple Silicon, macOS 15 ou plus récent) :** installez une fois les Command Line Tools d'Apple avec `xcode-select --install`
+(Xcode lui-même n'est pas nécessaire). Ouvrez le Terminal dans le dossier Strata et lancez `./setup.sh`. Le script compile
+le moteur Mac sur votre Mac (environ 7 minutes), pose les mêmes questions, télécharge le modèle et le démarre. La fois
+suivante, `./setup.sh` le démarre tout de suite. Quelle taille convient à votre Mac : [docs/MAC.md](docs/MAC.md).
+
+L'installateur détecte votre carte et prépare le bon moteur. Il demande quel modèle et quelle taille, combien de contexte
+(la quantité de texte que le modèle garde en tête) et s'il doit lire les images. Appuyez sur Entrée pour la réponse
+recommandée. Puis il télécharge le modèle (environ 70 Go) et le démarre. Si le téléchargement s'arrête, relancez le script
+et il reprend. Votre navigateur ouvre la page de Strata à l'adresse `http://127.0.0.1:8080`.
+
+> Pendant le démarrage du modèle, votre PC peut être lent ou ne plus répondre pendant 1 à 3 minutes (le plus longtemps la
+> première fois). Strata charge 35 à 55 Go dans votre RAM et en verrouille une partie pour la carte graphique. Patientez et
+> ne fermez pas la fenêtre.
+
+La fois suivante, relancez `START-HERE.bat` (ou `./setup.sh`). Il démarre tout de suite et ne télécharge rien deux fois.
+Fermez sa fenêtre pour arrêter le modèle. `UPDATE.bat` (`./update.sh`) met Strata à jour sans le démarrer. Mise à jour,
+Docker, plusieurs cartes, où vont les fichiers et toutes les options : [docs/INSTALL.md](docs/INSTALL.md).
+
+Pour mesurer votre PC, lancez `BENCH.bat` (`./bench.sh`). Cela prend 5 à 10 minutes et produit un rapport que vous pouvez
+partager ([comment](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)).
+
+**Facultatif : plus de vitesse sur une carte quand tout le modèle tient en RAM.** Deux réglages à activer soi-même, par
+RubenTorney (#1904, #1905). Ils aident quand vous utilisez une seule carte graphique et que votre RAM contient tous les
+experts, par exemple Q2_0 ou IQ3_XXS sur un PC de 64 Go. Ouvrez `strata-<model>.json` dans le dossier de données de Strata ([où](docs/INSTALL.md#where-things-are-stored)) et ajoutez :
+
+- `"--adapt-async", "1"` à la liste `"args"`. Le cache des experts se met alors à jour sur un thread auxiliaire au lieu de
+  mettre la réponse en pause. Mesuré sur une RTX 5070 (Windows, Q2_0) : +4 à 5 % en décodage, +7 à 10 % sur le code et les
+  longs documents. Les réponses peuvent différer légèrement de celles du réglage par défaut, et restent identiques d'une exécution à l'autre.
+- `"STRATA_PIN_BY_NEED": "1"` dans le bloc `"env"` (Windows). Windows ne peut verrouiller qu'environ la moitié de la RAM
+  pour la carte graphique, et ce réglage verrouille d'abord les experts dont la carte a le plus besoin. Mesuré sur la RTX 5070 : +4,4 % en lecture du prompt.
+
+```json
+"args": [ ..., "--adapt-async", "1" ],
+"env": { "STRATA_PIN_BY_NEED": "1" }
+```
+
+Redémarrez Strata après la modification. Pour annuler, supprimez les deux entrées.

 ## Comment ça marche ?

-Les modèles comme celui-ci tournent d'habitude sur des serveurs avec des centaines de gigaoctets de mémoire
-graphique. Votre carte graphique a 12-24 Go. Strata fait tenir le modèle en **répartissant le travail sur tout votre
-PC**. Pensez à une cuisine : ce que vous utilisez tout le temps reste sur le plan de travail, et le reste attend dans
-le placard.

 ## インストール

-### AI にセットアップしてもらう
+3つの方法から1つ選んでください。どれも同じエンジンを起動し、同じモデルを使います。

-Claude Code、Cursor、Codex、GitHub Copilot などの AI コーディングアシスタントを使っている場合は、次の文を貼り付けてください。
+### 方法A: Strata アプリ
+
+いちばん簡単な方法です。エンジンはアプリに入っているので、インストールしてモデルを選べばチャットを始められます。お使いのOSとグラフィックスカードに合うファイルを
+[リリースページ](https://github.com/Niko1221/Strata/releases/latest)からダウンロードしてください。どれか分からない場合は、表の下の説明を見てください。
+
+| OS | グラフィックスカード | ダウンロードするファイル |
+| --- | --- | --- |
+| **Windows 10 / 11** | NVIDIA RTX、ドライバー 580 以降 | [`Strata-0.2.3-windows-cuda13.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda13.exe) |
+| | NVIDIA、古いカード、またはドライバーが 580 より古い場合 | [`Strata-0.2.3-windows-cuda12.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda12.exe) |
+| | AMD Radeon RX 9000 シリーズまたは Radeon AI PRO R9700 | [`Strata-0.2.3-windows-hip.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip.exe) |
+| | AMD Radeon RX 7000 シリーズまたは Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-windows-hip-rdna3.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip-rdna3.exe) |
+| **Linux** | NVIDIA RTX、ドライバー 580 以降 | [`Strata-0.2.3-linux-nvidia-cuda13.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda13.AppImage) |
+| | NVIDIA、古いカード、またはドライバーが 580 より古い場合 | [`Strata-0.2.3-linux-nvidia-cuda12.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda12.AppImage) |
+| | AMD Radeon RX 9000 シリーズまたは Radeon AI PRO R9700 | [`Strata-0.2.3-linux-amd-rx9070.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx9070.AppImage) |
+| | AMD Radeon RX 7000 シリーズ | [`Strata-0.2.3-linux-amd-rx7900.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx7900.AppImage) |
+| | AMD Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-linux-amd-strixhalo.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-strixhalo.AppImage) |
+| **Mac**（Apple Silicon、macOS 15 以降） | 内蔵 | [`Strata-0.2.3-mac.dmg`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-mac.dmg) |
+
+**迷ったときは:** NVIDIA の場合、ドライバーがバージョン 580 以降なら `cuda13`、それより古ければ `cuda12` を選びます。`cuda12` は古いカードと古いドライバー向けです。
+`hip` と `amd` のファイルは AMD のカード用です。それ以外の AMD カード（RX 6000）には、まだ用意されたアプリがありません。
+[AMD のカード](docs/AMD_HIP.md)を見てください。
+
+そのあとの手順:
+
+- **Windows:** `.exe` を実行します。ユーザー単位でインストールされ、管理者権限は不要です。「Windows によってPCが保護されました」と表示されたら、
+  **詳細情報**を選び、**実行**を選んでください（インストーラーにはまだコード署名がありません）。
+- **Linux:** ファイルを実行可能にして（`chmod +x`）起動します。FUSE 2 が必要です。`sudo apt install libfuse2`（Ubuntu 22.04）
+  または `libfuse2t64`（Ubuntu 24.04 以降）を実行してください。
+- **Mac:** `.dmg` を開き、Strata を「アプリケーション」にドラッグします。
+
+最初の画面で、アプリがPCを調べて合うモデルをすすめます。インストールを押してください。モデルは大きく（約40〜70 GB）、中断しても続きからダウンロードできます。
+ウィンドウを閉じると、Strata とエンジンが止まります。
+
+### 方法B: ターミナル（1行）
+
+ターミナル版は `strata` コマンドです。スクリプトやサーバー、AI エージェント向けです。
+
+Linux と Mac:
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows（PowerShell）:
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+スクリプトはPCを調べ、ターミナル版をダウンロードし、SHA-256 を検証して、ホームフォルダに展開します。管理者権限は不要です。Windows では、終わったら
+新しいターミナルを開いてください。そのあと Strata を起動します。
+
+```sh
+strata launch
+```
+
+質問は1つずつ表示されます。モデル、コンテキスト、画像、接続を許可する相手の順です。そのあと、お使いのグラフィックスカード用のエンジン
+（署名付きで、使う前にテスト起動します）とモデルをダウンロードして、サーバーを開始します。スクリプトや AI エージェントからは、フラグを使います。
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+実行前にインストールスクリプトを読みたい場合は、先に `curl -fsSL <address> -o install.sh` でダウンロードし、内容を確認してから
+`sh install.sh` を実行してください。すべての画面とフラグは [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md) にあります。
+
+### 方法C: AI にセットアップを任せる
+
+Claude Code、Cursor、Codex、GitHub Copilot などのコーディングアシスタントに、次の文を貼り付けます。

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.
 ```

-AI がグラフィックカード、RAM、ディスクを確認して、PC に合ったモデルを選びます。インストールと起動を行い、
-アプリとの接続方法も案内します。また、Strata の [MCP サーバー](docs/MCP_SERVER.md) を使えば、
-AI ツールから Strata のインストール・起動・停止を行えます。
+AI はグラフィックスカード、RAM、ディスクを調べ、合うモデルを選んで、インストールと起動をし、アプリの接続方法を教えてくれます。
+AI ツールは [MCP サーバー](docs/MCP_SERVER.md)を通じて、Strata のインストール、起動、停止もできます。

-### 自分でやる
+自分でビルドしたい方は[ソースからビルド](#ソースからビルド)を見てください。

-[Strata をダウンロード](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip)して展開します（`git clone` でも構いません）。
-**Windows：** **`START-HERE.bat`** をダブルクリックします。**Linux：** Strata フォルダーで **`./setup.sh`** を実行します。
+## モデル

-NVIDIA でも AMD でも手順は同じです。インストーラーがカードを検出し、対応するエンジンを用意します。
-続いて、次の項目を設定します。
+アプリと `strata launch` は、メモリ量に合うモデルをすすめます。モデルは1つで、圧縮の度合いが違う複数のサイズがあります。
+小さいサイズは速く、大きいサイズは少し賢くなります。

- 使用するモデルとサイズ
- コンテキストの長さ（モデルが覚えておけるテキストの量）
- 画像を読み取る機能を使うかどうか
+### メモリが少ないなら Gyro

-各項目で Enter を押すと、推奨設定が選ばれます。設定が終わるとモデル（約 70 GB）をダウンロードし、起動します。
-ダウンロードが途中で止まった場合は、もう一度実行すると続きから再開できます。起動が完了すると、ブラウザーで
-`http://127.0.0.1:8080` が開き、Strata の画面が表示されます。
+[Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF)（agentionai 製）は、このモデルをいちばん小さく動かせる方法です。

-> **モデルの起動中は、1-3 分ほど PC の動作が遅くなったり、応答しなくなったりすることがあります**（初回は特に時間がかかります）。
-> Strata が 35-55 GB のデータを RAM に読み込み、その一部をグラフィックカード用に固定（ピン留め）しているためです。
-> 正常な動作なので、ウィンドウに表示される処理状況を確認しながら、閉じずにお待ちください。
+| サイズ | 必要なメモリ（RAM + VRAM） | ダウンロード | 内容 |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27.6 GB | 58.5 GB | ほかのサイズが入らないPC向け。品質は IQ2_XS より下がります。 |
+| **Gyro-M** | 35 GB | 92.0 GB | 品質は IQ3_XXS 程度で、GPUメモリの使用量は約20%少なくなります。回答の書き出しは Q2_0 より、12 GBの RTX 3060 で16%、R9700 で21%遅くなります。 |

-**次回からは** `START-HERE.bat`（または `./setup.sh`）を実行するだけですぐに起動できます。2 回目以降は、ダウンロード済みのファイルを再度取得する必要はありません。
-モデルを停止するにはウィンドウを閉じてください。`UPDATE.bat`（`./update.sh`）を使うと、Strata を起動せずに更新できます。
-更新方法や Docker、複数のカードの使い方、ファイルの保存先、各種オプションについては、[docs/INSTALL.md](docs/INSTALL.md)をご覧ください。
+Gyro は NVIDIA と AMD のカード（AMD は実験的）、および Linux 上の Intel Arc カード（Arc A750 で確認）で動きます。0.2.2 からは Apple Silicon の Mac でも動きます（32 GB の Mac mini で Gyro-S は 9 トークン/秒、エキスパートは SSD から読み込み）。詳細と測定結果は
+[docs/GYRO.md](docs/GYRO.md) にあります。`strata launch --model gyro-s` で起動します。

-## どのモデルを選べばいい
+### ほかのサイズ

-インストーラーが RAM の容量に合ったモデルをおすすめします。同じモデルでも、圧縮率によって複数のサイズが用意されています。
-サイズが小さいほど高速に動作し、大きいほど回答の品質が少し高くなります。
-
-| RAM | おすすめのモデル | 選ぶ理由 |
+| メモリ（RAM + VRAM） | 選ぶモデル | 備考 |
 | --- | --- | --- |
-| **32 GB** | **Coder** | 32 GB で動作するコーディング向けモデル（24 GB のカードがあれば Q2_0 と IQ2_XS も動作） |
-| **48 GB** | **IQ2_XS**（速度優先なら Q2_0） | これより大きいサイズはメモリに収まらない |
-| **64 GB** | **IQ2_XS**（おすすめ）、または IQ3_XXS / IQ3_S | どのサイズも利用可能。IQ3_S は回答の品質が最も高い一方、速度は最も遅い |
-| **96 GB 以上** | **IQ3_S**、または Unsloth の UD-IQ4_XS（約 4-bit） | 他のアプリを開いたままでも、最大サイズのモデルを動かせるだけの余裕がある |
+| **32 GB** | **Gyro-S**、またはコード向けの **[Coder](docs/MODELS.md#coder)** | Coder はRAM 32 GBが必要で、エキスパートを半分だけ保持するため、コード以外は弱くなります |
+| **40 GB** | **[Swift 1.5](docs/MODELS.md#swift-15)** IQ2_XS（39.2 GB）、または **Gyro-M**（35 GB） | Swift は答える前に考える時間が短くなります。Gyro-M は品質が IQ3_XXS に近いものの、回答の書き出しは Q2_0 より16〜21%遅くなります |
+| **48 GB** | **IQ3_XXS**（47.0 GB） | 遅くなりますが、品質は上がります |
+| **64 GB** | **IQ3_S**（54.8 GB）、オリジナルまたは Swift 1.5 | いちばん遅く、いちばん高品質です。公開されているテストでは完全版と同等です |
+| **96 GB 以上** | Unsloth の **UD-IQ4_XS**（RAM 約72 GB）から **Q8_0**（約136 GB）まで、4〜8ビット | 完全版に近づきます。RAM が足りないと、Strata は一部を SSD から読むため、ずっと遅くなります |

- **[Coder](docs/MODELS.md#coder)：** エキスパートを半分に減らしたコーディング向けモデルです。SWE-bench Verified ではフルモデルのスコアの
-  91% を達成しており（開発者による測定）、32 GB の RAM で動作します。ただし、コード以外の用途では性能が劣り、中国語などの CJK 言語の処理も苦手です（#438）。
-  こうした用途には、すべてのエキスパートを残した Q2_0、IQ2_XS、IQ3_S を選んでください。
- **[Swift 1.5](docs/MODELS.md#swift-15)：** 回答前の思考時間が大幅に短くなるようファインチューニングしたモデルです。
-  回答の品質をほぼ保ったまま、より短い時間で答えが返ってきます。
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs)：** Unsloth による約 4-bit のモデルです。回答の品質は IQ3_S と UD-Q4_K_XL の中間です。
-  ダウンロード容量は 94 GB です。RAM が約 80 GB 未満の場合、回答の生成中にモデルの一部を SSD から読み込むため、速度が落ちます（NVMe SSD を使うと改善します）。
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)**（試験的）：回答の品質がフルモデルに最も近いモデルです。
-  ただし、回答の生成中にモデルの大部分を SSD から読み込むため、RAM が 64 GB の PC では毎秒 7-8.5 トークン程度の速度になります。
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs)：** 手動でのセットアップが必要です。
-  インストーラーのメニューからは選べません。
+表の行より RAM が少なくても動くことがあります。Strata は自動で[低RAMモード](docs/MODELS.md#a-big-graphics-card-and-little-ram)に切り替わります。
+速度は落ち、グラフィックスカードが小さいとさらに大きく落ちます。

-各サイズのダウンロード情報や必要なメモリ容量は、[docs/MODELS.md](docs/MODELS.md)をご覧ください。後から別のモデルを追加する場合は、
-`SETUP.bat`（Linux：`./setup.sh --setup`）を実行してください。
+そのほかの選択肢:
+
+- **[Swift 1.5](docs/MODELS.md#swift-15)** はファインチューン版で、答える前に考える時間が短くなります。品質と RAM の必要量はほぼ同じです。
+- **[NVFP4](docs/NVFP4.md)** は NVIDIA カード向けの NVIDIA 製4ビット版です。すべてのエキスパートを RAM に置くには、約80 GBの RAM が必要です。
+- **[Qwen3.6-35B-A3B](docs/QWEN36.md)** は、より小さい別のモデルです。画像を読め、複数のリクエストに同時に答えられます。
+- **[OrcaRouter の Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs)** は手動で設定します。
+
+すべてのサイズ、ダウンロード、どの構成で何が動くかは [docs/MODELS.md](docs/MODELS.md) にあります。
+
+### DeepSeek V4.1-Flash（ターミナル版、0.2.4 から）
+
+[DeepSeek V4.1-Flash](https://huggingface.co/ISTA-DASLab/DeepSeek-V4.1-Flash-1017-GSQ-RCO-GGUF) は、これとは別のずっと大きなモデルです。下の 3 つのセットは ISTA-DASLab が作りました。Strata は、12 GB のグラフィックスカード 1 枚と 46 から 64 GB の RAM を持つ PC でこれを動かし、残りは SSD から読みます。NVIDIA RTX 30 から 50 シリーズのカードと Radeon AI PRO R9700 で動きます。専用のエンジンパッケージ `strata-dsv41` を使い、DeepSeek を選ぶと `strata launch` がダウンロードします。デスクトップアプリはまだ対応していません。
+
+| セット | ダウンロード | 元のモデルとの品質差 | 出力速度 |
+| --- | ---: | --- | --- |
+| **IQ1_M**（1.75 ビット） | 239 GB | KL 0.217、パープレキシティ 3.80（+21%）、コード +8.9%、エージェント作業 +10.2%、通常の英語の散文では弱めです。ISTA-DASLab のモデルカードによると、基本モデルのタスク平均の 98.7% を保ちます（AIME25、GPQA-Diamond、LiveCodeBench v6）。 | 未測定 |
+| **IQ2_XXS** (2.00 ビット) | 257 GB | KL 0.170、パープレキシティ 3.63（+15.5%）、コード +8.6%、エージェント作業 +5.3% | RTX 3060 で毎秒 6 から 9 トークン、RTX 5070 で約 5 |
+| **IQ2_XS** (2.25 ビット) | 274 GB | KL 0.107、パープレキシティ 3.37（+7.3%）、コード +3.2%、エージェント作業 +2.2% | Radeon AI PRO R9700 1 枚で毎秒約 11 トークン |
+| **IQ4_NL**（Engram テーブル、3 つ目のモデルではありません） | 111 GB、上の 3 つのダウンロードに含まれています | モデルが RAM または SSD から読む 4 ビットの Engram 参照テーブルです。3 つのセットはこの 1 つのファイル（`DeepSeek-V4.1-Flash-Engram-IQ4_NL.gguf`）を共有します。 | 該当なし |
+
+Radeon AI PRO R9700 4 枚：毎秒約 31 トークン、DSpark ありで 55 から 69。
+
+`strata launch --model ist-das-2.00bpw`（または `ist-das-1.75bpw`、`ist-das-2.25bpw`）で起動します。詳細、カードごとの速度、手動インストールは [docs/DEEPSEEK41.md](docs/DEEPSEEK41.md) にあります。
+
+## どのくらい速い？
+
+12 GBのグラフィックスカード（RTX 5070、Ryzen 5 7600、RAM 64 GB）での数値です。ほかのカードの結果は
+[各モデルの速度](docs/MODELS.md#how-fast-is-each-size)、[コミュニティの結果](docs/COMMUNITY_BENCHMARKS.md)を見てください。
+
+| モデル | 回答が出る速さ | プロンプトを読む速さ |
+| --- | --- | --- |
+| **Q2_0** | `████████████` 94 tokens/s | `████████████` 2,650 tokens/s |
+| **IQ2_XS** | `██████████░░` 79 tokens/s | `█████████░░░` 2,090 tokens/s |
+| **IQ3_XXS** | `████████░░░░` 62 tokens/s | `████████░░░░` 1,750 tokens/s |
+| **IQ3_S** | `███████░░░░░` 53 tokens/s | `███████░░░░░` 1,620 tokens/s |
+| **Coder** | `███████░░░░░` 55 tokens/s | `██████████░░` 2,180 tokens/s |
+
+1トークンは英単語の約¾にあたるので、毎秒60トークンは読む速さより速くなります。「プロンプトを読む速さ」は、長い文書やコード、チャット履歴を Strata が取り込む速さです。
+
+16 GBの AMD カード（RX 9070 XT、Ryzen 9 3900X、RAM 47 GB）での測定値:
+
+| モデル | 回答が出る速さ | プロンプトを読む速さ |
+| --- | --- | --- |
+| **Q2_0** | `████████░░░░` 60 tokens/s | `█████░░░░░░░` 1,160 tokens/s |
+| **IQ2_XS** | `███████░░░░░` 52 tokens/s | `█████░░░░░░░` 1,110 tokens/s |
+| **Coder** | `██████░░░░░░` 44 tokens/s | `██████░░░░░░` 1,420 tokens/s |
+
+バーは2つの表で同じ目盛りです。VRAM が多いカードほど速くなり、RTX 3090（24 GB）なら毎秒100〜140トークンほどになるはずです。各数値のエンジンのバージョンは
+[DETAILS.md](docs/DETAILS.md#speed-measured) にあります。

 ## 使い方

-<p align="center"><img src="docs/media/runpagoda.png" width="900" alt="Strata の Monitor タブ（左）と、コードを生成するコーディングエージェント（右）"><br>
-<sub>動画に登場する五重塔の庭を作成中の画面。左が Strata の <b>Monitor</b>、右がコードを生成しているコーディングエージェント</sub></p>
+### アプリで

- **ブラウザーで使う：** `http://127.0.0.1:8080` を開きます。チャット用の **Chat**、モデルや GPU/CPU/RAM の状態をリアルタイムで確認できる **Monitor**、
-  設定や接続先のアドレスを確認できる **About** の各タブがあります。
- **アプリやコーディングエージェントと連携する：** 「OpenAI-compatible」プロバイダーを追加し、ベース URL に
-  **`http://127.0.0.1:8080/v1`** を指定します。API キーとモデル名には任意の値を指定できます。
-  - Anthropic API を使うアプリ：`http://127.0.0.1:8080/v1/messages`（Claude Code では
-    `ANTHROPIC_BASE_URL=http://127.0.0.1:8080` を設定）。
-  - Codex CLI など、OpenAI Responses API を使うアプリ：`/v1/responses`
-    （[設定方法](docs/DETAILS.md#the-responses-api-and-codex-cli)）。
- **思考（Thinking）の設定：** チャットのメニュー、または連携先アプリの「reasoning effort」で **off、low、medium、high** から選びます。
-  off が最も速く、難しい質問には high が向いています。
- **画像を読み取る：** セットアップ時に「Images?」で yes を選びます。その後、チャットの **Picture** ボタンをクリックするか、連携先のアプリで画像を添付してください。
-  AMD のカードを使う場合、Linux では CPU で画像を読み取ります。Windows ではまだ画像の読み取りに対応していません。
- **スマートフォンや別の PC から使う：** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>` で起動します。API キーは必ず設定してください。
- **リクエストは 1 つずつ：** 標準設定では 1 つずつ処理し、それ以外のリクエストは順番を待ちます。同時に処理するには、
-  `"parallel": 2` を設定してください（[BATCHING.md](docs/BATCHING.md)）。12 GB のカードでは、リクエストごとの回答速度が落ちます。
- **長いプロンプトを送る：** チャットの最初のメッセージは全文を読み込むため、30,000 トークンあたり約 1 分かかります。
-  2 通目以降は数秒で応答が始まります。
+アプリには、**チャット**、モデルとGPU・CPU・RAMの状態を見る**モニター**、**モデル**ページ、**設定**があります。チャットはPC上のフォルダで作業できます。
+**手動**モードでは、ファイルを変更したりコマンドを実行したりする前に確認します。`/loop 10m <やること>` と入力すると、チャットを開いている間、メッセージを10分ごとに繰り返し送ります。

-[チャットの保存場所](docs/INSTALL.md#where-things-are-stored)や[API の詳細](docs/DETAILS.md#using-it)も参照してください。
+チャットは DuckDuckGo（または Bing）でウェブ検索ができ、アカウントは不要です。**設定、ツール**で検索キーを追加することもできます。
+検索は、PCの外に何かを送る唯一の機能で、送られるのは検索語です。
+
+2つのモデルを動かすには、**複数のモデルを実行**をオンにして、それぞれのモデルに同じメーカーのカードを1枚ずつ割り当てます。

+| OpenAI 互換（ほとんどのアプリとエージェント） | `http://127.0.0.1:8080/v1`（API キーもモデル名も何でも可） |
+| Anthropic API（Claude Code など） | `http://127.0.0.1:8080`、`/v1` は付けません。これらのアプリは `/v1/messages` を自分で付けます。Claude Code: `ANTHROPIC_BASE_URL=http://127.0.0.1:8080` |
+| OpenAI Responses API（Codex CLI） | `http://127.0.0.1:8080/v1/responses`（[設定方法](docs/DETAILS.md#the-responses-api-and-codex-cli)） |
+
+`strata connect` は、OpenCode、Codex CLI、Claude Code、oh-my-pi、pi、Hermes Agent、OpenClaw の正確な設定を表示します。
+`strata connect opencode --write` は、確認したうえでファイルを書き込み、バックアップを残します。
+
+### 画像
+
+画像を読めるモデルでは、画像は初期設定でオンです。チャットに画像を添付または貼り付けるか、アプリから送ってください。
+グラフィックスカードが24 GB未満のときは、画像リーダーがプロセッサで動きます（画像1枚につき数秒、カードのメモリは使いません）。24 GB以上のときはグラフィックスカードで動きます。
+このルールは NVIDIA と AMD で同じです。画像はモデルごとにオフにでき、`--vision off`、`--vision gpu`、`--vision cpu` でリーダーを選べます。
+
+このルールの根拠となる数値です。Radeon AI PRO R9700 では、カードのリーダーは260トークンの画像に57 ms、プロセッサのリーダーは3.1秒かかりました。
+16 GBのカード（Tesla P100 と RTX A4000、Linux）では、カードのリーダーを使うとテキストの速度が3〜5%下がりました。
+本来モデルが使う約1.4 GBをリーダーが占めるためです。Mac ではメモリ量にかかわらず GPU が読み取ります（32 GB の M4 で260トークンの画像に0.45秒、共有メモリを約1.2 GB使います）。プロセッサでは1枚あたり約50秒かかるため、`--vision cpu` を指定したときだけ使います。
+
+### 知っておくと便利なこと
+
+- 思考のレベル（**off、low、medium、high**）は、チャットのメニューか、お使いのアプリの「reasoning effort」で選びます。off がいちばん速くなります。
+- Strata は初期設定では、一度に1つのリクエストに答えます。同時に複数処理するには、`strata launch` で `--parallel N` を使うか、設定に
+  `"parallel": 2` を書きます（[BATCHING.md](docs/BATCHING.md)）。12 GBのカードでは、1つずつの回答が遅くなります。
+- Strata はチャットの最初のメッセージを全文読みます。30,000トークンあたり約1分かかります。続きのメッセージは数秒で始まります。
+- チャットの保存場所と API 全体: [docs/INSTALL.md](docs/INSTALL.md#where-things-are-stored)、[docs/DETAILS.md](docs/DETAILS.md#using-it)。

+## ソースからビルド
+
+<details>
+<summary>リポジトリから Windows、Linux、Mac 用にビルドする</summary>
+
+[Strata をダウンロード](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip)して展開するか、`git clone` します。
+**Windows:** `START-HERE.bat` をダブルクリックします。**Linux:** Strata フォルダで `./setup.sh` を実行します。
+
+**Mac（Apple Silicon、macOS 15 以降）:** 最初に一度、`xcode-select --install` で Apple のコマンドラインツールをインストールします
+（Xcode 本体は不要です）。Strata フォルダでターミナルを開き、`./setup.sh` を実行します。Mac 用エンジンをお使いの Mac 上でビルドし
+（約7分）、同じ質問をして、モデルをダウンロードし、起動します。2回目以降は `./setup.sh` ですぐに起動します。
+お使いの Mac に合うサイズは [docs/MAC.md](docs/MAC.md) を見てください。
+
+インストーラーはカードを見つけて、合うエンジンを設定します。どのモデルとサイズにするか、コンテキストをどれだけにするか（モデルが一度に覚えておけるテキストの量）、
+画像を読ませるかを聞かれます。おすすめの答えでよければ Enter を押します。そのあとモデル（約70 GB）をダウンロードして起動します。
+ダウンロードが止まったら、もう一度実行すると続きから再開します。ブラウザで `http://127.0.0.1:8080` の Strata ページが開きます。
+
+> モデルの起動中は、PCが1〜3分ほど（初回がいちばん長い）遅くなったり、応答しなくなったりすることがあります。Strata は35〜55 GBをRAMに読み込み、
+> その一部をグラフィックスカード用に固定するためです。ウィンドウを閉じずに待ってください。
+
+次回からは `START-HERE.bat`（または `./setup.sh`）をもう一度実行するだけです。すぐに起動し、同じものを2回ダウンロードすることはありません。ウィンドウを閉じるとモデルが止まります。
+`UPDATE.bat`（`./update.sh`）は、起動せずに Strata を更新します。更新、Docker、複数のカード、ファイルの保存先、すべてのオプションは
+[docs/INSTALL.md](docs/INSTALL.md) にあります。
+
+PCの性能を測るには、`BENCH.bat`（`./bench.sh`）を実行します。5〜10分かかり、共有できるレポートが作られます
+（[方法](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)）。
+
+**オプション: モデル全体がRAMに入るとき、1枚のカードをさらに速くする。** RubenTorney による、自分でオンにする2つの設定です（#1904、#1905）。
+グラフィックスカードが1枚で、RAM がすべてのエキスパートを保持できるときに効果があります。たとえば64 GBのPCでの Q2_0 や IQ3_XXS です。
+Strata のデータフォルダにある `strata-<model>.json`（[場所](docs/INSTALL.md#where-things-are-stored)）を開いて、次を追加します。
+
+- `"args"` のリストに `"--adapt-async", "1"` を追加します。エキスパートキャッシュが、回答を止めずに補助スレッドで更新されます。
+  RTX 5070（Windows、Q2_0）での測定: デコードが4〜5%、コードや長い文書では7〜10%速くなりました。回答は初期設定と少し違うことがありますが、実行ごとの結果は変わりません。
+- `"env"` ブロックに `"STRATA_PIN_BY_NEED": "1"` を追加します（Windows）。Windows ではグラフィックスカード用に固定できる RAM が半分ほどしかありません。
+  この設定は、カードが最初に必要とするエキスパートを優先して固定します。RTX 5070 での測定: プロンプトの読み取りが4.4%速くなりました。
+
+```json
+"args": [ ..., "--adapt-async", "1" ],
+"env": { "STRATA_PIN_BY_NEED": "1" }
+```
+
+変更したら Strata を再起動してください。元に戻すには、2つの項目を削除します。

+
+## 仕組み
+
+このようなモデルは、ふつう数百GBのグラフィックスメモリを持つサーバーで動きます。お使いのグラフィックスカードは12〜24 GBです。Strata は、PC全体で作業を分担して、モデルを収めます。
+図書館にたとえてみます。
+
+- モデルは、24,576人の小さな専門家（「エキスパート」）からなるチームです。24,576冊の参考書のようなものです。1つの単語に必要なのは、そのうち10冊だけです。
+- **グラフィックスカードは机です。** 小さくて速く、最もよく使う約4,000冊が開いて置いてあります。
+- **RAM は閲覧室の書棚です。** 24,576冊すべてがここにあります。単語に必要な本が机になければ、プロセッサがすぐに書棚から読み、その間もカードは作業を続けます。
+- **SSD は書庫です。** 29 GBの参照テーブルがしまってあります。モデルは単語ごとにその数行だけを読むので、RAM に置いておく必要はありません。
+
+<p align="center"><img src="docs/media/how-it-works.svg" width="860" alt="The model's 24,576 experts: the busiest on the graphics card, all of them in RAM, a lookup table on the SSD"></p>
+
+小さな助手が、次の数単語も予想します。大きなモデルがそれをまとめて確認し、正しいものだけを残します。答えは同じで、1.6〜1.8倍早く返ります。
+長い文章は、一度に最大8,192トークンの大きな塊で、毎秒1,000トークンを超える速さで読みます。

 ## うまくいかないとき

- **初回起動時に PC が応答しなくなる。** モデルの読み込み中は、一時的に応答しなくなることがあります。ウィンドウを閉じずにお待ちください。
-  10 分たっても応答しない場合は、PC を再起動して他のアプリを閉じてからやり直すか、モデルのサイズを小さくしてください。
- **ダウンロードやインストールが途中で止まる。** `START-HERE.bat`（または `./setup.sh`）をもう一度実行してください。
-  中断したところから再開できます。
- **動作が極端に遅く、ディスクのアクセスランプが点滅し続ける。または「the engine stopped unexpectedly」と表示される。** RAM の空き容量が不足しています。
-  ブラウザーなど、RAM を多く使う他のアプリを閉じるか、小さいモデル（Q2_0 または IQ2_XS）を選んでください。
- **ポート 8080 が使用中と表示される。** Strata がすでに起動しています。起動済みのウィンドウを探してください。
+- **Strata を初めて起動したときに、PCが固まりました。** モデルを RAM に読み込んでいます。ウィンドウを閉じずに待ってください。10分たっても固まったままなら、
+  PCを再起動し、ほかのプログラムを閉じてからもう一度試すか、小さいサイズを選んでください。
+- **ダウンロードやインストールの途中で止まりました。** アプリか `strata launch` をもう一度起動するか、`START-HERE.bat`（または
+  `./setup.sh`）をもう一度実行してください。止まったところから再開します。
+- **とても遅い、ディスクのランプが点滅し続ける、または「エンジンが予期せず停止しました」と表示される。** PCの空き RAM が足りません。
+  ほかのプログラムを閉じるか（ブラウザはメモリを多く使います）、Q2_0 や IQ2_XS のような小さいサイズを選んでください。
+- **このPCに合うエンジンがないと表示される。** アプリでは、**設定、エンジン**を開いて**エンジンを更新**を押します。ターミナルでは
+  `strata update` を実行します。`strata doctor` で、どのエンジンファイルがインストールされているか分かります。
+- **ポート 8080 はすでに使われていると表示される。** Strata がすでに動いています。ウィンドウを探してください。

-## しくみ
-
-この規模のモデルは通常、数百ギガバイトの GPU メモリを搭載したサーバーで動かします。一方、手元のグラフィックカードのメモリは
-12-24 GB 程度です。Strata は **PC 全体で処理を分担する** ことで、こうした環境でもモデルを動かせるようにしています。
-台所で、よく使うものは調理台に置き、それ以外は食品庫にしまっておくような仕組みです。

-
- **モデルは「エキスパート」と呼ばれる 24,576 個の小さな処理単位から構成されています。** 1 語の生成に必要なのは、このうち 10 個だけです。
- **グラフィックカード** に、使用頻度の高い数千個のエキスパートを置きます。**RAM** にはすべてのエキスパートを保持し、

-We measured it on two ordinary gaming PCs. A token is about ¾ of a word.
+- **Runs on a gaming PC.** 32 GB of RAM and graphics memory together is enough to start.
+- **Works with your tools.** It speaks the OpenAI and Anthropic APIs, so Claude Code, Codex CLI, OpenCode and other agents connect to it.

 ## What you need

-| | |
+**You need at least 32 GB of RAM and graphics memory (VRAM) together.** On a Mac or a Ryzen AI Max, that is the unified
+memory. More memory gives a bigger model or a faster one.
+
+- A 32 GB PC with a 12-16 GB card runs the Coder.
+- 64 GB of RAM runs every size.
+
+| Your computer | Details |
 | --- | --- |
-| **Graphics card** | **NVIDIA** GeForce RTX 20, 30, 40 or 50 series, or **AMD** Radeon RX 7900 XT / XTX, RX 7800 XT / 7700 XT, RX 9060 XT, RX 9070 / 9070 XT, Radeon AI PRO R9700 or RX 6800 / 6900 series. It needs **12 GB of VRAM or more**. |
-| **RAM** | 32 GB or more. Your RAM decides [which model](#which-model-should-i-pick) fits. 64 GB runs every size. |
-| **Disk** | About 80 GB free. Use an SSD if you can: the first start is much faster. |
-| **System** | Windows 10 / 11 or Linux, and a current graphics driver from NVIDIA or AMD. |
+| **NVIDIA** GeForce RTX 20, 30, 40, 50 series (12 GB or more) | Install the app or the Terminal. |

-The installer sets up everything else. Two or three cards can share the model ([multi-GPU](docs/MULTI_GPU.md)).
+Also needed:

-Experimental, written and tested by community members on their own machines:
+- about 80 GB of free disk (an SSD makes the first start much faster)
+- Windows 10 / 11, Linux or macOS
+- a current graphics driver

- **Older graphics cards** (Tesla P40 / V100, GTX 10, Radeon VII / MI50, RX 6700 XT, RX 5500 XT): [Older GPUs](docs/OLDER_GPUS.md).
- **Intel Arc**, built from source on Linux: [Intel Arc](docs/INTEL_ARC.md).
- **AMD Ryzen AI Max (Strix Halo)**, built from source on Linux: [Strix Halo](docs/STRIX_HALO.md).
- **Older processors without AVX2**: they work, but slowly. [Older CPUs](docs/INSTALL.md#older-cpus-experimental).
-
-The full list: [docs/INSTALL.md](docs/INSTALL.md#what-you-need).
+Two or three cards of the same make can share a model ([multi-GPU](docs/MULTI_GPU.md)). Strata never splits a model across
+NVIDIA and AMD cards. Full list: [docs/INSTALL.md](docs/INSTALL.md#what-you-need).

 ## Install

-### Let your AI set it up
+Pick one option. They all start the same engine and use the same models.

-Do you use an AI coding assistant (Claude Code, Cursor, Codex, GitHub Copilot, ...)? Paste this into it:
+### Option A: the Strata app

+their own: install `hip-rdna3` (Windows) or `amd-rx7900` (Linux), and on a PC with an RX 6000 card it fetches the RX 6000 engine by itself
+(also `strata update`). That engine is built but not yet tested on a real RX 6000 card: see [AMD cards](docs/AMD_HIP.md).
+
+Then:
+
+- **Windows:** run the `.exe`. It installs for your user and needs no administrator rights. If Windows says "Windows
+  protected your PC", choose **More info**, then **Run anyway** (the installer is not code-signed yet).
+- **Linux:** make the file runnable (`chmod +x`) and start it. It needs FUSE 2: `sudo apt install libfuse2` (Ubuntu 22.04)
+  or `libfuse2t64` (Ubuntu 24.04 and newer).
+- **Mac:** open the `.dmg` and drag Strata onto Applications.
+
+On the first screen the app reads your PC and recommends a model that fits. Press install. The model is a big download
+(about 40-70 GB) and continues where it stopped if it is interrupted. Closing the window stops Strata and the engine.
+
+### Option B: the Terminal (one line)
+
+The Terminal is the `strata` command, for scripts, servers and AI agents.
+
+Linux and Mac:
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows (PowerShell):
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+The script checks your PC, downloads the Terminal, verifies its SHA-256 and unpacks it into your home folder. It needs no
+administrator rights. On Windows, open a new terminal window afterwards. Then start Strata:
+
+```sh
+strata launch
+```
+
+It asks one question at a time: model, context, pictures, who may connect. Then it downloads the engine for your graphics
+card (signed, and test-started before use) and the model, and starts serving. For scripts and AI agents, use flags:
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+To read the install script before it runs, download it first with `curl -fsSL <address> -o install.sh`, read it, then run
+`sh install.sh`. All screens and flags: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md).
+
+### Option C: let your AI set it up
+
+Paste this into Claude Code, Cursor, Codex, GitHub Copilot or another coding assistant:

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.
 ```

-It checks your graphics card, RAM and disk and picks the model that fits. Then it installs and starts it and tells
-you how to connect your apps. AI tools can also install, start and stop Strata through its
-[MCP server](docs/MCP_SERVER.md).
+It checks your graphics card, RAM and disk, picks the model that fits, installs and starts it, and tells you how to
+connect your apps. AI tools can also install, start and stop Strata through its [MCP server](docs/MCP_SERVER.md).

-### Or do it yourself
+Prefer to build it yourself? See [Build from source](#build-from-source).

-[Download Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) and unzip it (or `git clone` it).
-**Windows:** double-click **`START-HERE.bat`**. **Linux:** run **`./setup.sh`** in the Strata folder.
+## Models

-The steps are the same for NVIDIA and AMD. The installer finds your card and sets up the right engine for it. It
-asks you a few questions:
+The app and `strata launch` recommend a model for your memory. It is one model in several sizes, compressed more or less.
+Smaller sizes are faster. Larger sizes are a bit smarter.

- which model and which size,
- how much context (how much text the model keeps in mind),
- whether it should read pictures.
+### Low on memory? Try Gyro

-Press Enter each time for the recommended answer. Then it downloads the model (about 70 GB) and starts it. If the
-download stops, run it again: it continues where it left off. Your browser opens the Strata app at
-`http://127.0.0.1:8080`.
+[Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF) (by agentionai) is the smallest way to run this model.

-> **While the model starts, your PC can be slow or stop responding for 1-3 minutes** (longest the first time).
-> Strata loads 35-55 GB into your RAM and locks part of it for the graphics card. This is normal. Wait, and don't
-> close the window. The window shows what Strata is doing.
+| Size | Memory it needs (RAM + VRAM) | Download | What it is |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27.6 GB | 58.5 GB | For PCs that fit nothing else. Quality is lower than IQ2_XS. |
+| **Gyro-M** | 35 GB | 92.0 GB | About IQ3_XXS quality with about 20% less GPU memory. It writes answers 16% (12 GB RTX 3060) to 21% (R9700) slower than Q2_0. |

-**Next time**, run `START-HERE.bat` (or `./setup.sh`) again. It starts right away and downloads nothing twice. Close
-its window to stop the model. `UPDATE.bat` (`./update.sh`) updates Strata without starting it. Updating, Docker,
-several cards, where the files go and every option: [docs/INSTALL.md](docs/INSTALL.md).
+Gyro runs on NVIDIA and AMD cards (AMD is experimental) on Intel Arc cards on Linux (tested on an Arc A750) and, from 0.2.2, on Apple Silicon Macs (Gyro-S on a 32 GB Mac mini: 9 tok/s, streaming from the SSD; [docs/MAC.md](docs/MAC.md#gyro-s-and-gyro-m-agentionais-trellis-experts)). Details and measurements:
+[docs/GYRO.md](docs/GYRO.md). Start it with `strata launch --model gyro-s`.

-## Which model should I pick?
+### The other sizes

-The installer recommends one for your RAM. The same model comes in several sizes, compressed more or less. Smaller
-sizes are faster. Larger sizes are a bit smarter.
+The tiers count your RAM plus your VRAM, less 5 GB that Windows and the system keep for themselves. Every other size stays a choice.

-| Your RAM | Take | Why |
+| Your memory (RAM + VRAM) | Take | Notes |
 | --- | --- | --- |
-| **32 GB** | **Coder** | it fits 32 GB, and it is made for code (with a 24 GB card, Q2_0 and IQ2_XS run too) |
-| **48 GB** | **IQ2_XS** (or Q2_0, the fastest) | the larger sizes do not fit |
-| **64 GB** | **IQ2_XS** (recommended), or IQ3_XXS / IQ3_S | every size fits; IQ3_S is the best and the slowest |
-| **96 GB or more** | **IQ3_S**, or Unsloth's UD-IQ4_XS (~4-bit) | room for the largest sizes with everything else open |
+| **32 GB** | **Gyro-S**, or the **[Coder](docs/MODELS.md#coder)** for code | The Coder needs 32 GB of RAM and keeps half of the experts, so it is weaker outside code |
+| **40 GB** | **[Swift 1.5](docs/MODELS.md#swift-15)** IQ2_XS (39.2 GB), or **Gyro-M** (35 GB) | Swift thinks for a shorter time before it answers. Gyro-M is close to IQ3_XXS in quality, but it writes answers 16-21% slower than Q2_0 |
+| **48 GB** | **IQ3_XXS** (47.0 GB) | Slower, better |
+| **64 GB** | **IQ3_S** (54.8 GB), the original or Swift 1.5 | The slowest, the best: it matches the full model on the published tests |
+| **96 GB or more** | Unsloth's **UD-IQ4_XS** (about 72 GB of RAM) to **Q8_0** (about 136 GB), 4 to 8 bit | Closer to the full model. With less RAM, Strata reads part of them from the SSD, which is much slower |

- **[Coder](docs/MODELS.md#coder):** a coding version with half of the experts removed. It reaches 91% of the full
-  model's SWE-bench Verified score (measured by its authors) and fits 32 GB of RAM. It is weaker outside code,
-  including Chinese and other CJK text (#438). For those, take Q2_0, IQ2_XS or IQ3_S, which keep every expert.
- **[Swift 1.5](docs/MODELS.md#swift-15):** a fine-tune that thinks for a much shorter time before it answers. You
-  get the answer sooner, at about the same quality.
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs):** Unsloth's ~4-bit version, between IQ3_S and
-  UD-Q4_K_XL in quality. A 94 GB download. With less than ~80 GB of RAM, Strata reads part of it from the SSD
-  while it answers, so it is slower there (an NVMe SSD helps).
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)** (experimental): the closest to the full
-  model. But Strata reads most of it from the SSD while it answers, so it writes only 7-8.5 tokens/s on a 64 GB PC.
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs):** you set it up by hand. It is
-  not in the installer's menu.
+Less RAM than a row says can still work: Strata switches to its
+[low-RAM mode](docs/MODELS.md#a-big-graphics-card-and-little-ram) by itself. Expect it to be slower, and much slower
+with a small graphics card.

-Sizes, downloads and what fits where: [docs/MODELS.md](docs/MODELS.md). To add another model later, run
-`SETUP.bat` (Linux: `./setup.sh --setup`).
+More choices:
+
+- **[Swift 1.5](docs/MODELS.md#swift-15)** is a fine-tune that thinks for a shorter time before it answers, at about the same quality and RAM.
+- **[NVFP4](docs/NVFP4.md)** is NVIDIA's 4-bit version for NVIDIA cards. It needs about 80 GB of RAM to keep every expert in RAM.
+- **[Qwen3.6-35B-A3B](docs/QWEN36.md)** is a smaller, different model that reads pictures and can answer several requests at once.
+- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs)** is set up by hand.
+
+Every size, download and what fits where: [docs/MODELS.md](docs/MODELS.md).
+
+### DeepSeek V4.1-Flash (in the Terminal, from 0.2.4)
+
+[DeepSeek V4.1-Flash](https://huggingface.co/ISTA-DASLab/DeepSeek-V4.1-Flash-1017-GSQ-RCO-GGUF) is a different, much bigger model. ISTA-DASLab made the three sets below. Strata runs them on a PC with one 12 GB graphics card and 46 to 64 GB of RAM, and reads the rest from your SSD. It runs on NVIDIA RTX 30 to 50 cards and on the Radeon AI PRO R9700. It uses its own engine package, `strata-dsv41`, which `strata launch` downloads when you pick DeepSeek. The desktop app does not offer it yet.
+
+| Set | Download | Quality against the original model | Writes at |
+| --- | ---: | --- | --- |
+| **IQ1_M** (1.75 bits) | 239 GB | KL 0.217, perplexity 3.80 (+21%); code +8.9%, agent work +10.2%; weaker on plain English prose. ISTA-DASLab's model card: keeps 98.7% of the base model's task average (AIME25, GPQA-Diamond, LiveCodeBench v6). | not measured yet |
+| **IQ2_XXS** (2.00 bits) | 257 GB | KL 0.170, perplexity 3.63 (+15.5%); code +8.6%, agent work +5.3% | 6 to 9 tokens/s on an RTX 3060, about 5 on an RTX 5070 |
+| **IQ2_XS** (2.25 bits) | 274 GB | KL 0.107, perplexity 3.37 (+7.3%); code +3.2%, agent work +2.2% | about 11 tokens/s on one Radeon AI PRO R9700 |
+| **IQ4_NL** (Engram table, not a third model) | 111 GB, already in all three downloads above | The 4-bit Engram lookup table the model reads from RAM or SSD. All three sets use this one file (`DeepSeek-V4.1-Flash-Engram-IQ4_NL.gguf`). | n/a |
+
+4x Radeon AI PRO R9700: about 31 tokens/s, 55 to 69 with DSpark.
+
+Start it with `strata launch --model ist-das-2.00bpw` (or `ist-das-1.75bpw`, `ist-das-2.25bpw`). Details, speeds per card and the manual install: [docs/DEEPSEEK41.md](docs/DEEPSEEK41.md).
+
+## How fast is it?
+
+Based on a 12 GB graphics card (RTX 5070, Ryzen 5 7600, 64 GB RAM). See results from other cards:
+[speed of each model](docs/MODELS.md#how-fast-is-each-size), [community results](docs/COMMUNITY_BENCHMARKS.md).
+
+| Model | Answers appear at | Reads your prompt at |
+| --- | --- | --- |
+| **Q2_0** | `████████████` 94 tokens/s | `████████████` 2,650 tokens/s |
+| **IQ2_XS** | `██████████░░` 79 tokens/s | `█████████░░░` 2,090 tokens/s |
+| **IQ3_XXS** | `████████░░░░` 62 tokens/s | `████████░░░░` 1,750 tokens/s |
+| **IQ3_S** | `███████░░░░░` 53 tokens/s | `███████░░░░░` 1,620 tokens/s |
+| **Coder** | `███████░░░░░` 55 tokens/s | `██████████░░` 2,180 tokens/s |
+
+A token is about ¾ of a word, so 60 tokens per second is faster than you can read. "Reads your prompt" is how fast Strata
+takes in a long document, code or chat history.
+
+Measured on a 16 GB AMD card (RX 9070 XT, Ryzen 9 3900X, 47 GB RAM):
+
+| Model | Answers appear at | Reads your prompt at |
+| --- | --- | --- |
+| **Q2_0** | `████████░░░░` 60 tokens/s | `█████░░░░░░░` 1,160 tokens/s |
+| **IQ2_XS** | `███████░░░░░` 52 tokens/s | `█████░░░░░░░` 1,110 tokens/s |
+| **Coder** | `██████░░░░░░` 44 tokens/s | `██████░░░░░░` 1,420 tokens/s |
+
+The bars use one scale for both tables. A card with more VRAM is faster: an RTX 3090 (24 GB) should write about 100-140
+tokens per second. The engine version behind each number is in [DETAILS.md](docs/DETAILS.md#speed-measured).

 ## Using it

-<p align="center"><img src="docs/media/runpagoda.png" width="900" alt="The Strata app's Monitor tab next to a coding agent"><br>
-<sub>The Strata app's <b>Monitor</b> (left) while a coding agent writes the pagoda garden from the video (right)</sub></p>
+### In the app

- **In the browser:** open `http://127.0.0.1:8080`. It has **Chat**, a live **Monitor** of the model and your
-  GPU/CPU/RAM, and **About** with the settings and addresses.
- **Your apps and coding agents:** add an "OpenAI-compatible" provider with the base URL
-  **`http://127.0.0.1:8080/v1`**. Any API key and any model name work.
-  - Apps that use Anthropic's API: `http://127.0.0.1:8080/v1/messages` (Claude Code:
-    `ANTHROPIC_BASE_URL=http://127.0.0.1:8080`).
-  - Codex CLI and other apps that use the OpenAI Responses API: `/v1/responses`
-    ([setup](docs/DETAILS.md#the-responses-api-and-codex-cli)).
- **Thinking:** choose **off, low, medium or high** in the chat menu or in your app's "reasoning effort". Off is the
-  fastest. High is best for hard questions.
- **Pictures:** say yes to "Images?" in setup. Then click **Picture** in the chat, or attach pictures in your app.
-  AMD cards read pictures on Linux through the processor; on Windows they can't yet.
- **From your phone or another PC:** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>`. Always set a key.
- **One request at a time:** by default Strata answers one request, and the others wait. To answer several at once,
-  set `"parallel": 2` ([BATCHING.md](docs/BATCHING.md)). On a 12 GB card this makes each answer slower.
- **Long prompts:** Strata reads the first message of a chat in full, about 1 minute per 30,000 tokens. Follow-up
-  messages start in seconds.
+The app has a **Chat**, a **Monitor** of the model and your GPU, CPU and RAM, a **Models** page and **Settings**. The chat
+can work in a folder on your PC. In **Manual** mode it asks before it changes a file or runs a command. Type
+`/loop 10m <what to do>` to repeat a message every 10 minutes while the chat is open.

-More: [where your chats are stored](docs/INSTALL.md#where-things-are-stored), [the API](docs/DETAILS.md#using-it).
+The chat can search the web with DuckDuckGo (or Bing), with no account. You can add a search key under **Settings, Tools**.
+Search is the one feature that sends something off your PC, the search words.

-## Something went wrong?
+To run two models, turn on **Run multiple models** and give each model its own card of the same make.

- **My PC froze the first time Strata started.** This is normal while it loads the model. Wait, and don't close the
-  window. Still frozen after 10 minutes? Restart the PC, close other programs and try again, or pick a smaller size.
- **It stopped while downloading or installing.** Run `START-HERE.bat` (or `./setup.sh`) again. It continues where
-  it stopped.
- **It's very slow and the disk light keeps blinking, or it says "the engine stopped unexpectedly".** Your PC does
-  not have enough free RAM. Close other programs (browsers use a lot), or pick a smaller size (Q2_0 or IQ2_XS).
- **It says port 8080 is already in use.** Strata is already running. Look for its window.

+<sub><code>strata monitor</code> while the model writes a reply: speed, GPU, memory and the recent requests</sub></p>
+
+```sh
+strata launch                                  # guided screens: model, context, pictures, access, then serve

+strata doctor                                  # check the installed engine files
+```
+
+`strata --help` lists everything. Starting and serving never download anything. Only the install, `strata launch` (when
+you choose a model) and `strata update` do. To reach Strata from your phone or another PC, use
+`strata launch --access lan`. It makes an API key (recommended; add `--no-api-key` to go without, with a warning). No browser opens unless
+you add `--open`. Guide: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md). Whole client: [docs/TERMINAL.md](docs/TERMINAL.md).
+
+### With AI agents
+
+An agent installs Strata with the one-line command in Option B and runs
+`strata launch --model NAME --yes --no-tui`. The steps, flags and exit codes are in [docs/AI_SETUP.md](docs/AI_SETUP.md),
+and the repository rules are in [AGENTS.md](AGENTS.md).
+
+### Connect your other apps
+
+| App type | Base URL |
+| --- | --- |
+| OpenAI-compatible (most apps and agents) | `http://127.0.0.1:8080/v1` (any API key, any model name) |
+| Anthropic API (Claude Code and others) | `http://127.0.0.1:8080`, without `/v1`. These apps add `/v1/messages` themselves. Claude Code: `ANTHROPIC_BASE_URL=http://127.0.0.1:8080` |
+| OpenAI Responses API (Codex CLI) | `http://127.0.0.1:8080/v1/responses` ([setup](docs/DETAILS.md#the-responses-api-and-codex-cli)) |
+
+`strata connect` prints the exact settings for OpenCode, Codex CLI, Claude Code, oh-my-pi, pi, Hermes Agent and OpenClaw.
+`strata connect opencode --write` writes the file after asking and keeps a backup.
+
+### Pictures
+
+Pictures are on by default for models that can read them. Attach or paste a picture in the chat, or send it from your app.
+The picture reader runs on the processor when your graphics card has less than 24 GB (a few seconds per picture, nothing
+taken from the card's memory) and on the graphics card from 24 GB. The rule is the same for NVIDIA and AMD. Turn pictures
+off per model, or choose the reader with `--vision off`, `--vision gpu` or `--vision cpu`.
+
+The numbers behind the rule: on a Radeon AI PRO R9700 the card's reader took 57 ms for a 260-token picture and the
+processor's took 3.1 s. On 16 GB cards (Tesla P100 and RTX A4000, Linux) the card's reader cost 3-5% of text speed,
+because it holds about 1.4 GB that the model would use otherwise. On a Mac the reader runs on the Mac's GPU whatever its memory (0.45 s for a 260-token picture on an M4 with 32 GB, about 1.2 GB of the shared
+memory); the processor reader needs about 50 s per picture there, so it runs only when you ask for it with `--vision cpu`.
+
+### Good to know
+
+- Choose the thinking level (**off, low, medium or high**) in the chat menu or in your app's "reasoning effort". Off is fastest.
+- Strata answers one request at a time by default. For several at once, use `--parallel N` in `strata launch` or
+  `"parallel": 2` in the config ([BATCHING.md](docs/BATCHING.md)). On a 12 GB card this makes each answer slower.
+- Strata reads the first message of a chat in full, about 1 minute per 30,000 tokens. Follow-up messages start in seconds.
+- Where your chats are stored and the whole API: [docs/INSTALL.md](docs/INSTALL.md#where-things-are-stored), [docs/DETAILS.md](docs/DETAILS.md#using-it).

+## Build from source
+
+<details>
+<summary>Windows, Linux and Mac from the repository</summary>
+
+[Download Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) and unzip it, or `git clone` it.
+**Windows:** double-click `START-HERE.bat`. **Linux:** run `./setup.sh` in the Strata folder.
+
+**Mac (Apple Silicon, macOS 15 or newer):** install Apple's Command Line Tools once with `xcode-select --install`
+(Xcode itself is not needed). Open Terminal in the Strata folder and run `./setup.sh`. It builds the Mac engine on your
+Mac (about 7 minutes), asks the same questions, downloads the model and starts it. Next time, `./setup.sh` starts it
+right away. Which size fits your Mac: [docs/MAC.md](docs/MAC.md).
+
+The installer finds your card and sets up the right engine. It asks which model and size, how much context (how much text
+the model keeps in mind) and whether it should read pictures. Press Enter for the recommended answer. Then it downloads the
+model (about 70 GB) and starts it. If the download stops, run it again and it continues. Your browser opens the Strata
+page at `http://127.0.0.1:8080`.
+
+> While the model starts, your PC can be slow or stop responding for 1-3 minutes (longest the first time). Strata loads
+> 35-55 GB into your RAM and locks part of it for the graphics card. Wait, and don't close the window.
+
+Next time, run `START-HERE.bat` (or `./setup.sh`) again. It starts right away and downloads nothing twice. Close its
+window to stop the model. `UPDATE.bat` (`./update.sh`) updates Strata without starting it. Updating, Docker, several cards,
+where the files go and every option: [docs/INSTALL.md](docs/INSTALL.md).
+
+To measure your PC, run `BENCH.bat` (`./bench.sh`). It takes 5-10 minutes and writes a report you can share
+([how](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)).
+
+**Optional: more speed on one card when the whole model fits in RAM.** Two opt-in settings by RubenTorney (#1904, #1905).
+They help when you run one graphics card and your RAM holds every expert, for example Q2_0 or IQ3_XXS on a 64 GB PC. Open
+`strata-<model>.json` in the Strata data folder ([where](docs/INSTALL.md#where-things-are-stored)) and add:
+
+- `"--adapt-async", "1"` to the `"args"` list. The expert cache then updates on a helper thread instead of pausing the
+  answer. Measured on an RTX 5070 (Windows, Q2_0): +4-5% decode, +7-10% on code and long documents. Answers can differ
+  slightly from the default and stay the same from run to run.
+- `"STRATA_PIN_BY_NEED": "1"` in the `"env"` block (Windows). Windows can lock only about half the RAM for the graphics
+  card, and this locks the experts the card needs first. Measured on the RTX 5070: +4.4% prompt reading.
+
+```json
+"args": [ ..., "--adapt-async", "1" ],
+"env": { "STRATA_PIN_BY_NEED": "1" }
+```
+
+Restart Strata after the change. To undo, remove the two entries.

 ## How does it work?

 Models like this one usually run on servers with hundreds of gigabytes of graphics memory. Your graphics card has
-12-24 GB. Strata makes the model fit by **sharing the work across your whole PC**. Think of a kitchen: the things
-you use all the time stay on the counter, and the rest waits in the pantry.
+12-24 GB. Strata makes the model fit by sharing the work across your whole PC. Picture a library.
+
+- The model is a team of 24,576 small specialists ("experts"), like 24,576 reference books. Each word needs only 10 of them.
+- **Your graphics card is the desk.** It is small and fast. The roughly 4,000 books used most often lie open on it.
+- **Your RAM is the shelves in the reading room.** All 24,576 books are there. When a word needs a book that is not on the
+  desk, your processor reads it from the shelf at once, while the card keeps working.
+- **Your SSD is the archive.** It holds a 29 GB lookup table. The model reads a few rows of it per word, so it does not
+  need to sit in RAM.

- **The model is a team of 24,576 small specialists ("experts").** Each word needs only 10 of them.
- **Your graphics card** keeps the few thousand experts that are used most often. **Your RAM** holds all of them,
-  and **your processor** works on the rest at the same time. **Your SSD** holds a big lookup table.
+A small helper also guesses the next few words. The big model checks all of them at once and keeps the right ones. You get
+the same answer, 1.6-1.8x sooner. Long texts are read in big pieces, up to 8,192 tokens at a time, at over 1,000 tokens
+per second.

+## Something went wrong?
+
+- **My PC froze the first time Strata started.** It loads the model into RAM. Wait, and don't close the window. Still
+  frozen after 10 minutes? Restart the PC, close other programs and try again, or pick a smaller size.
+- **It stopped while downloading or installing.** Start the app or `strata launch` again, or run `START-HERE.bat` (or
+  `./setup.sh`) again. It continues where it stopped.
+- **It is very slow, the disk light keeps blinking, or it says "the engine stopped unexpectedly".** Your PC does not have
+  enough free RAM. Close other programs (browsers use a lot), or pick a smaller size such as Q2_0 or IQ2_XS.
+- **It says there is no engine for this PC.** In the app, open **Settings, Engine** and press **Update engine**. In the
+  Terminal, run `strata update`. `strata doctor` shows which engine files are installed.
+- **It says port 8080 is already in use.** Strata is already running. Look for its window.
+
+More problems and fixes: [docs/TROUBLESHOOTING.md](docs/TROUBLESHOOTING.md). Still stuck? Open an
+[issue](https://github.com/Niko1221/Strata/issues). In the app, attach the file from **Settings, Engine, Diagnostics, View
+logs, Save logs**. In the Terminal, paste the output of `strata doctor`. From source, attach `strata-<model>.log` from the
+Strata folder. For a security problem, report it privately: [SECURITY.md](SECURITY.md).

-O Strata roda o **[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)** num PC comum. É um modelo
-de IA grande e inteligente que normalmente precisa de um servidor. Ele conversa, escreve código, entende imagens e
-funciona com seus apps e agentes de programação. Nada sai do seu PC.
+O Strata roda o **[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)**, um modelo de 125 bilhões de parâmetros que
+normalmente precisa de um servidor, num PC comum. Ele conversa, escreve código, lê imagens e funciona com os seus aplicativos e
+agentes de programação. Suas conversas e arquivos ficam no seu PC.

-## Qual é a velocidade?
+**Primeira vez aqui?** Veja [o que você precisa](#o-que-você-precisa) e depois [instale o app](#opção-a-o-app-strata).

-Medimos em dois PCs gamer comuns. Um token equivale a cerca de ¾ de uma palavra.
+- **Roda num PC gamer.** 32 GB somando memória RAM e memória da placa de vídeo já bastam para começar.
+- **Funciona com as suas ferramentas.** Ele fala as APIs da OpenAI e da Anthropic, então Claude Code, Codex CLI, OpenCode e outros agentes se conectam a ele.
+- **Lê imagens.** Já vêm ativadas.
+- **Gratuito.** Licença MIT, sem conta, sem nuvem.
+- **Privado.** Sem telemetria. O que o Strata baixa, quando usa a internet e como confere os downloads está em [docs/SAFETY.md](docs/SAFETY.md).

- **Escreve respostas:** a velocidade com que a resposta aparece numa conversa curta. 60 tokens por segundo é mais rápido do que você consegue ler.
- **Lê seu prompt:** a velocidade com que ele absorve o que você envia (aqui, um documento, código ou histórico de conversa de 32K tokens).

-| **Placa de vídeo** | **NVIDIA** GeForce RTX séries 20, 30, 40 ou 50, ou **AMD** Radeon RX 7900 XT / XTX, RX 7800 XT / 7700 XT, RX 9060 XT, RX 9070 / 9070 XT, Radeon AI PRO R9700 ou séries RX 6800 / 6900. Ela precisa de **12 GB de VRAM ou mais**. |
-| **RAM** | 32 GB ou mais. Sua RAM decide [qual modelo](#qual-modelo-devo-escolher) cabe. Com 64 GB, roda qualquer tamanho. |
-| **Disco** | Cerca de 80 GB livres. Use um SSD se puder: a primeira inicialização fica bem mais rápida. |
-| **Sistema** | Windows 10 / 11 ou Linux, e um driver de vídeo atualizado da NVIDIA ou da AMD. |

-O instalador cuida de todo o resto. Duas ou três placas podem dividir o modelo ([multi-GPU](docs/MULTI_GPU.md)).
+Você também precisa de:

-Experimental, escrito e testado por membros da comunidade nas próprias máquinas:
+- cerca de 80 GB de espaço livre no disco (um SSD deixa a primeira inicialização bem mais rápida)
+- Windows 10 / 11, Linux ou macOS
+- um driver de vídeo atualizado

 ## Instalação

-### Deixe sua IA instalar
+Escolha uma opção. Todas iniciam o mesmo mecanismo e usam os mesmos modelos.

-Você usa um assistente de programação com IA (Claude Code, Cursor, Codex, GitHub Copilot, ...)? Cole isto nele:
+### Opção A: o app Strata
+
+O jeito mais fácil. O app já traz o mecanismo: instale, escolha um modelo e converse. Baixe o arquivo para o seu sistema e a sua
+placa de vídeo na [página de releases](https://github.com/Niko1221/Strata/releases/latest). Não sabe qual? Veja a explicação
+logo abaixo da tabela.
+
+| Sistema | Sua placa de vídeo | Arquivo para baixar |
+| --- | --- | --- |
+| **Windows 10 / 11** | NVIDIA RTX, driver 580 ou mais novo | [`Strata-0.2.3-windows-cuda13.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda13.exe) |
+| | NVIDIA, placa mais antiga ou driver anterior ao 580 | [`Strata-0.2.3-windows-cuda12.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda12.exe) |
+| | AMD Radeon série RX 9000 ou Radeon AI PRO R9700 | [`Strata-0.2.3-windows-hip.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip.exe) |
+| | AMD Radeon série RX 7000 ou Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-windows-hip-rdna3.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip-rdna3.exe) |
+| **Linux** | NVIDIA RTX, driver 580 ou mais novo | [`Strata-0.2.3-linux-nvidia-cuda13.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda13.AppImage) |
+| | NVIDIA, placa mais antiga ou driver anterior ao 580 | [`Strata-0.2.3-linux-nvidia-cuda12.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda12.AppImage) |
+| | AMD Radeon série RX 9000 ou Radeon AI PRO R9700 | [`Strata-0.2.3-linux-amd-rx9070.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx9070.AppImage) |
+| | AMD Radeon série RX 7000 | [`Strata-0.2.3-linux-amd-rx7900.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx7900.AppImage) |
+| | AMD Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-linux-amd-strixhalo.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-strixhalo.AppImage) |
+| **Mac** (Apple Silicon, macOS 15 ou mais novo) | integrada | [`Strata-0.2.3-mac.dmg`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-mac.dmg) |
+
+**Se você estiver em dúvida:** para NVIDIA, use `cuda13` se o seu driver for a versão 580 ou mais nova, e `cuda12` nos outros casos. O `cuda12`
+serve para placas e drivers mais antigos. Os arquivos `hip` e `amd` são para placas AMD. Outras placas AMD (RX 6000) ainda não têm app pronto: veja [Placas AMD](docs/AMD_HIP.md).
+
+Depois:
+
+- **Windows:** execute o `.exe`. Ele instala só para o seu usuário e não pede direitos de administrador. Se o Windows disser "O Windows
+  protegeu o computador", escolha **Mais informações** e depois **Executar assim mesmo** (o instalador ainda não tem assinatura de código).
+- **Linux:** torne o arquivo executável (`chmod +x`) e inicie. É preciso ter o FUSE 2: `sudo apt install libfuse2` (Ubuntu 22.04)
+  ou `libfuse2t64` (Ubuntu 24.04 e mais novos).
+- **Mac:** abra o `.dmg` e arraste o Strata para Aplicativos.
+
+Na primeira tela, o app lê o seu PC e recomenda um modelo que caiba nele. Clique em instalar. O modelo é um download grande
+(cerca de 40 a 70 GB) e continua de onde parou se for interrompido. Fechar a janela encerra o Strata e o mecanismo.
+
+### Opção B: o Terminal (uma linha)
+
+O Terminal é o comando `strata`, para scripts, servidores e agentes de IA.
+
+Linux e Mac:
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows (PowerShell):
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+O script confere o seu PC, baixa o Terminal, verifica o SHA-256 e descompacta na sua pasta pessoal. Não precisa de direitos de
+administrador. No Windows, abra uma nova janela do terminal depois. Então inicie o Strata:
+
+```sh
+strata launch
+```
+
+Ele faz uma pergunta por vez: modelo, contexto, imagens, quem pode se conectar. Depois baixa o mecanismo para a sua placa de vídeo
+(assinada e testada antes do uso) e o modelo, e começa a servir. Em scripts e agentes de IA, use flags:
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+Para ler o script de instalação antes de executá-lo, baixe-o primeiro com `curl -fsSL <address> -o install.sh`, leia e então rode
+`sh install.sh`. Todas as telas e flags: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md).
+
+### Opção C: deixe a sua IA configurar
+
+Cole isto no Claude Code, Cursor, Codex, GitHub Copilot ou outro assistente de programação:

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.
 ```

-Ele verifica sua placa de vídeo, RAM e disco e escolhe o modelo que cabe. Depois instala, inicia e explica como
-conectar seus apps. Ferramentas de IA também podem instalar, iniciar e parar o Strata pelo
-[servidor MCP](docs/MCP_SERVER.md) dele.
+Ele confere a sua placa de vídeo, a RAM e o disco, escolhe o modelo que cabe, instala e inicia, e diz como conectar os seus
+aplicativos. Ferramentas de IA também podem instalar, iniciar e parar o Strata pelo [servidor MCP](docs/MCP_SERVER.md) dele.

-### Ou faça você mesmo
+Prefere compilar por conta própria? Veja [Compilar a partir do código-fonte](#compilar-a-partir-do-código-fonte).

-[Baixe o Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) e descompacte (ou use `git clone`).
-**Windows:** clique duas vezes em **`START-HERE.bat`**. **Linux:** rode **`./setup.sh`** na pasta do Strata.
+## Modelos

-Os passos são os mesmos para NVIDIA e AMD. O instalador encontra sua placa e configura o engine certo para ela.
-Ele faz algumas perguntas:
-
- qual modelo e qual tamanho,
- quanto contexto (quanto texto o modelo guarda na memória),
- se ele deve entender imagens.
-
-Aperte Enter em cada uma para usar a resposta recomendada. Depois ele baixa o modelo (cerca de 70 GB) e o inicia.
-Se o download parar, rode de novo: ele continua de onde parou. Seu navegador abre o app do Strata em
-`http://127.0.0.1:8080`.
-
-> **Enquanto o modelo inicia, seu PC pode ficar lento ou parar de responder por 1-3 minutos** (mais na primeira vez).
-> O Strata carrega 35-55 GB na sua RAM e reserva parte dela para a placa de vídeo. Isso é normal. Espere e não
-> feche a janela. A janela mostra o que o Strata está fazendo.
-
-**Da próxima vez**, rode `START-HERE.bat` (ou `./setup.sh`) de novo. Ele inicia na hora e não baixa nada duas
-vezes. Feche a janela para parar o modelo. `UPDATE.bat` (`./update.sh`) atualiza o Strata sem iniciá-lo.
-Atualização, Docker, várias placas, onde ficam os arquivos e todas as opções: [docs/INSTALL.md](docs/INSTALL.md).
-
-## Qual modelo devo escolher?
-
-O instalador recomenda um de acordo com sua RAM. O mesmo modelo vem em vários tamanhos, mais ou menos comprimidos.
+O app e o `strata launch` recomendam um modelo para a sua memória. É um único modelo em vários tamanhos, mais ou menos comprimidos.
 Os tamanhos menores são mais rápidos. Os maiores são um pouco mais inteligentes.

-| Sua RAM | Escolha | Por quê |
+### Pouca memória? Experimente o Gyro
+
+O [Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF) (da agentionai) é a menor forma de rodar este modelo.
+
+| Tamanho | Memória necessária (RAM + VRAM) | Download | O que é |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27,6 GB | 58,5 GB | Para PCs onde nenhum outro tamanho cabe. A qualidade é menor que a do IQ2_XS. |
+| **Gyro-M** | 35 GB | 92,0 GB | Qualidade próxima à do IQ3_XXS, com cerca de 20% menos memória da GPU. Ele escreve as respostas 16% mais devagar que o Q2_0 numa RTX 3060 de 12 GB e 21% mais devagar numa R9700. |
+
+O Gyro roda em placas NVIDIA e AMD (AMD é experimental) em placas Intel Arc no Linux (testado numa Arc A750) e, desde a 0.2.2, em Macs com Apple Silicon (Gyro-S num Mac mini de 32 GB: 9 tokens/s, com os especialistas lidos do SSD). Detalhes e medições:
+[docs/GYRO.md](docs/GYRO.md). Inicie com `strata launch --model gyro-s`.
+
+### Os outros tamanhos
+
+| Sua memória (RAM + VRAM) | Escolha | Observações |
 | --- | --- | --- |
-| **32 GB** | **Coder** | cabe em 32 GB e é feito para código (com uma placa de 24 GB, Q2_0 e IQ2_XS também rodam) |
-| **48 GB** | **IQ2_XS** (ou Q2_0, o mais rápido) | os tamanhos maiores não cabem |
-| **64 GB** | **IQ2_XS** (recomendado), ou IQ3_XXS / IQ3_S | todos os tamanhos cabem; IQ3_S é o melhor e o mais lento |
-| **96 GB ou mais** | **IQ3_S**, ou o UD-IQ4_XS da Unsloth (~4-bit) | espaço para os maiores tamanhos com todo o resto aberto |
+| **32 GB** | **Gyro-S**, ou o **[Coder](docs/MODELS.md#coder)** para código | O Coder precisa de 32 GB de RAM e mantém metade dos experts, então é mais fraco fora de código |

+| **64 GB** | **IQ3_S** (54,8 GB), o original ou o Swift 1.5 | O mais lento, o melhor: empata com o modelo completo nos testes publicados |
+| **96 GB ou mais** | **UD-IQ4_XS** da Unsloth (cerca de 72 GB de RAM) até **Q8_0** (cerca de 136 GB), de 4 a 8 bits | Mais perto do modelo completo. Com menos RAM, o Strata lê parte deles do SSD, o que é bem mais lento |

- **[Coder](docs/MODELS.md#coder):** uma versão para programação com metade dos experts removida. Ela alcança 91%
-  da pontuação do modelo completo no SWE-bench Verified (medido pelos autores) e cabe em 32 GB de RAM. É mais fraca
-  fora do código, inclusive em chinês e outros textos CJK (#438). Para isso, escolha Q2_0, IQ2_XS ou IQ3_S, que
-  mantêm todos os experts.
- **[Swift 1.5](docs/MODELS.md#swift-15):** um fine-tune que pensa por bem menos tempo antes de responder. Você
-  recebe a resposta mais cedo, com quase a mesma qualidade.
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs):** a versão de ~4 bits da Unsloth, entre IQ3_S e
-  UD-Q4_K_XL em qualidade. Um download de 94 GB. Com menos de ~80 GB de RAM, o Strata lê uma parte dele do SSD
-  enquanto responde, então ali ele fica mais lento (um SSD NVMe ajuda).
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)** (experimental): o mais próximo do modelo
-  completo. Mas o Strata lê a maior parte dele do SSD enquanto responde, então ele escreve só 7-8.5 tokens/s num PC
-  com 64 GB.
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs):** você configura à mão. Ele
-  não está no menu do instalador.
+Com menos RAM do que a linha indica, ainda pode funcionar: o Strata muda sozinho para o
+[modo de pouca RAM](docs/MODELS.md#a-big-graphics-card-and-little-ram). Espere mais lentidão, e muito mais com uma placa de vídeo pequena.

+### DeepSeek V4.1-Flash (no Terminal, a partir da 0.2.4)
+
+[DeepSeek V4.1-Flash](https://huggingface.co/ISTA-DASLab/DeepSeek-V4.1-Flash-1017-GSQ-RCO-GGUF) é outro modelo, bem maior. A ISTA-DASLab fez os três conjuntos abaixo. O Strata os executa em um PC com uma placa de vídeo de 12 GB e de 46 a 64 GB de RAM, e lê o resto do seu SSD. Ele roda em placas NVIDIA RTX das séries 30 a 50 e na Radeon AI PRO R9700. Usa um pacote de motor próprio, `strata-dsv41`, que o `strata launch` baixa quando você escolhe o DeepSeek. O app de desktop ainda não o oferece.
+
+| Conjunto | Download | Qualidade em relação ao modelo original | Responde a |
+| --- | ---: | --- | --- |
+| **IQ1_M** (1,75 bits) | 239 GB | KL 0,217, perplexidade 3,80 (+21%); código +8,9%, tarefas de agente +10,2%; mais fraco em prosa comum em inglês. Segundo o cartão do modelo da ISTA-DASLab, mantém 98,7% da média de tarefas do modelo base (AIME25, GPQA-Diamond, LiveCodeBench v6). | ainda não medida |
+| **IQ2_XXS** (2.00 bits) | 257 GB | KL 0,170, perplexidade 3,63 (+15,5%); código +8,6%, tarefas de agente +5,3% | 6 a 9 tokens/s em uma RTX 3060, cerca de 5 em uma RTX 5070 |
+| **IQ2_XS** (2.25 bits) | 274 GB | KL 0,107, perplexidade 3,37 (+7,3%); código +3,2%, tarefas de agente +2,2% | cerca de 11 tokens/s em uma Radeon AI PRO R9700 |
+| **IQ4_NL** (tabela Engram, não é um terceiro modelo) | 111 GB, já incluídos nos três downloads acima | A tabela de consulta Engram de 4 bits que o modelo lê da RAM ou do SSD. Os três conjuntos usam este único arquivo (`DeepSeek-V4.1-Flash-Engram-IQ4_NL.gguf`). | n/a |
+
+4x Radeon AI PRO R9700: cerca de 31 tokens/s, 55 a 69 com DSpark.
+
+Inicie com `strata launch --model ist-das-2.00bpw` (ou `ist-das-1.75bpw`, `ist-das-2.25bpw`). Detalhes, velocidades por placa e a instalação manual: [docs/DEEPSEEK41.md](docs/DEEPSEEK41.md).
+
+## Qual é a velocidade?
+
+Com base numa placa de vídeo de 12 GB (RTX 5070, Ryzen 5 7600, 64 GB de RAM). Veja resultados de outras placas:
+[velocidade de cada modelo](docs/MODELS.md#how-fast-is-each-size), [resultados da comunidade](docs/COMMUNITY_BENCHMARKS.md).
+
+| Modelo | As respostas aparecem a | Lê o seu prompt a |
+| --- | --- | --- |
+| **Q2_0** | `████████████` 94 tokens/s | `████████████` 2.650 tokens/s |
+| **IQ2_XS** | `██████████░░` 79 tokens/s | `█████████░░░` 2.090 tokens/s |
+| **IQ3_XXS** | `████████░░░░` 62 tokens/s | `████████░░░░` 1.750 tokens/s |
+| **IQ3_S** | `███████░░░░░` 53 tokens/s | `███████░░░░░` 1.620 tokens/s |
+| **Coder** | `███████░░░░░` 55 tokens/s | `██████████░░` 2.180 tokens/s |
+
+Um token equivale a cerca de ¾ de palavra, então 60 tokens por segundo é mais rápido do que você lê. "Lê o seu prompt" é a velocidade com que o Strata
+absorve um documento longo, um código ou um histórico de conversa.
+
+Medido numa placa AMD de 16 GB (RX 9070 XT, Ryzen 9 3900X, 47 GB de RAM):
+
+| Modelo | As respostas aparecem a | Lê o seu prompt a |
+| --- | --- | --- |
+| **Q2_0** | `████████░░░░` 60 tokens/s | `█████░░░░░░░` 1.160 tokens/s |
+| **IQ2_XS** | `███████░░░░░` 52 tokens/s | `█████░░░░░░░` 1.110 tokens/s |
+| **Coder** | `██████░░░░░░` 44 tokens/s | `██████░░░░░░` 1.420 tokens/s |
+
+As barras usam a mesma escala nas duas tabelas. Uma placa com mais VRAM é mais rápida: uma RTX 3090 (24 GB) deve escrever cerca de 100 a 140
+tokens por segundo. A versão do mecanismo por trás de cada número está em [DETAILS.md](docs/DETAILS.md#speed-measured).

 ## Como usar

-<p align="center"><img src="docs/media/runpagoda.png" width="900" alt="A aba Monitor do app Strata ao lado de um agente de programação"><br>
-<sub>O <b>Monitor</b> do app Strata (à esquerda) enquanto um agente de programação escreve o jardim com pagode do vídeo (à direita)</sub></p>
+### No app

- **No navegador:** abra `http://127.0.0.1:8080`. Lá tem o **Chat**, um **Monitor** ao vivo do modelo e da sua
-  GPU/CPU/RAM, e o **About** com as configurações e os endereços.
- **Seus apps e agentes de programação:** adicione um provedor "OpenAI-compatible" com a URL base
-  **`http://127.0.0.1:8080/v1`**. Qualquer chave de API e qualquer nome de modelo funcionam.
-  - Apps que usam a API da Anthropic: `http://127.0.0.1:8080/v1/messages` (Claude Code:
-    `ANTHROPIC_BASE_URL=http://127.0.0.1:8080`).
-  - Codex CLI e outros apps que usam a OpenAI Responses API: `/v1/responses`
-    ([configuração](docs/DETAILS.md#the-responses-api-and-codex-cli)).
- **Raciocínio:** escolha **off, low, medium ou high** no menu do chat ou no "reasoning effort" do seu app. Off é o
-  mais rápido. High é o melhor para perguntas difíceis.
- **Imagens:** responda sim para "Images?" na instalação. Depois clique em **Picture** no chat, ou anexe imagens no
-  seu app. Placas AMD entendem imagens no Linux usando o processador; no Windows, ainda não.
- **Do seu celular ou de outro PC:** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>`. Sempre defina uma chave.
- **Uma requisição por vez:** por padrão, o Strata responde uma requisição e as outras esperam. Para responder
-  várias ao mesmo tempo, defina `"parallel": 2` ([BATCHING.md](docs/BATCHING.md)). Numa placa de 12 GB, isso deixa
-  cada resposta mais lenta.
- **Prompts longos:** o Strata lê a primeira mensagem de uma conversa inteira, cerca de 1 minuto a cada 30,000
-  tokens. As mensagens seguintes começam em segundos.
+O app tem um **Chat**, um **Monitor** do modelo e da sua GPU, CPU e RAM, uma página de **Modelos** e as **Configurações**. O chat
+pode trabalhar numa pasta do seu PC. No modo **Manual**, ele pergunta antes de alterar um arquivo ou executar um comando. Digite
+`/loop 10m <o que fazer>` para repetir uma mensagem a cada 10 minutos enquanto o chat estiver aberto.

-Mais: [onde suas conversas ficam salvas](docs/INSTALL.md#where-things-are-stored), [a API](docs/DETAILS.md#using-it).
+O chat pode pesquisar na web com o DuckDuckGo (ou o Bing), sem conta. Você pode adicionar uma chave de busca em **Configurações, Ferramentas**.
+A busca é o único recurso que envia algo para fora do seu PC: os termos da pesquisa.

-## Algo deu errado?
+Para rodar dois modelos, ative **Executar vários modelos** e dê a cada modelo a sua própria placa da mesma marca.

- **Meu PC travou na primeira vez que o Strata iniciou.** Isso é normal enquanto ele carrega o modelo. Espere e não
-  feche a janela. Ainda travado depois de 10 minutos? Reinicie o PC, feche outros programas e tente de novo, ou
-  escolha um tamanho menor.
- **Parou durante o download ou a instalação.** Rode `START-HERE.bat` (ou `./setup.sh`) de novo. Ele continua de
-  onde parou.
- **Está muito lento e a luz do disco não para de piscar, ou aparece "the engine stopped unexpectedly".** Seu PC
-  não tem RAM livre suficiente. Feche outros programas (navegadores usam muita), ou escolha um tamanho menor (Q2_0
-  ou IQ2_XS).
- **Diz que a porta 8080 já está em uso.** O Strata já está rodando. Procure a janela dele.

+### No Terminal
+
+<p align="center"><img src="docs/media/terminal-monitor.png" width="900" alt="The Strata Terminal monitor overview while the model writes a reply"><br>
+<sub><code>strata monitor</code> enquanto o modelo responde: velocidade, GPU, memória e as solicitações recentes</sub></p>
+

+strata doctor                                  # confere os arquivos do mecanismo instalada
+```
+
+`strata --help` lista tudo. Iniciar e servir nunca baixam nada. Só a instalação, o `strata launch` (quando você
+escolhe um modelo) e o `strata update` baixam. Para acessar o Strata do celular ou de outro PC, use
+`strata launch --access lan`. Ele cria uma chave de API e não inicia numa rede sem uma. Nenhum navegador abre, a menos que
+você adicione `--open`. Guia: [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md). Cliente completo: [docs/TERMINAL.md](docs/TERMINAL.md).
+
+### Com agentes de IA
+
+Um agente instala o Strata com o comando de uma linha da Opção B e executa
+`strata launch --model NAME --yes --no-tui`. Os passos, as flags e os códigos de saída estão em [docs/AI_SETUP.md](docs/AI_SETUP.md),
+e as regras do repositório estão em [AGENTS.md](AGENTS.md).
+
+### Conecte os seus outros aplicativos
+
+| Tipo de aplicativo | URL base |
+| --- | --- |
+| Compatível com OpenAI (a maioria dos apps e agentes) | `http://127.0.0.1:8080/v1` (qualquer chave de API, qualquer nome de modelo) |
+| API da Anthropic (Claude Code e outros) | `http://127.0.0.1:8080`, sem `/v1`. Esses aplicativos adicionam `/v1/messages` sozinhos. Claude Code: `ANTHROPIC_BASE_URL=http://127.0.0.1:8080` |
+| OpenAI Responses API (Codex CLI) | `http://127.0.0.1:8080/v1/responses` ([configuração](docs/DETAILS.md#the-responses-api-and-codex-cli)) |
+
+`strata connect` mostra as configurações exatas para OpenCode, Codex CLI, Claude Code, oh-my-pi, pi, Hermes Agent e OpenClaw.
+`strata connect opencode --write` grava o arquivo depois de perguntar e mantém um backup.
+
+### Imagens
+
+As imagens vêm ativadas nos modelos que sabem lê-las. Anexe ou cole uma imagem no chat, ou envie pelo seu aplicativo.
+O leitor de imagens roda no processador quando a sua placa de vídeo tem menos de 24 GB (alguns segundos por imagem, sem tirar nada
+da memória da placa) e roda na placa de vídeo a partir de 24 GB. A regra é a mesma para NVIDIA e AMD. Desative as imagens
+por modelo, ou escolha o leitor com `--vision off`, `--vision gpu` ou `--vision cpu`.
+
+Os números por trás da regra: numa Radeon AI PRO R9700, o leitor da placa levou 57 ms para uma imagem de 260 tokens e o do
+processador levou 3,1 s. Em placas de 16 GB (Tesla P100 e RTX A4000, Linux), o leitor da placa custou de 3 a 5% da velocidade do texto,
+porque ocupa cerca de 1,4 GB que o modelo usaria de outra forma. No Mac, a GPU faz a leitura, seja qual for a memória (0,45 s para uma imagem de 260 tokens em um M4 de 32 GB, cerca de 1,2 GB da memória compartilhada);
+o processador leva cerca de 50 s por imagem, então só lê com `--vision cpu`.
+
+### Bom saber
+
+- Escolha o nível de raciocínio (**off, low, medium ou high**) no menu do chat ou no "reasoning effort" do seu aplicativo. Off é o mais rápido.
+- Por padrão, o Strata responde a um pedido por vez. Para vários ao mesmo tempo, use `--parallel N` no `strata launch` ou
+  `"parallel": 2` na configuração ([BATCHING.md](docs/BATCHING.md)). Numa placa de 12 GB, isso deixa cada resposta mais lenta.
+- O Strata lê a primeira mensagem de uma conversa por inteiro, cerca de 1 minuto a cada 30.000 tokens. As mensagens seguintes começam em segundos.

+## Compilar a partir do código-fonte
+
+<details>
+<summary>Windows, Linux e Mac a partir do repositório</summary>
+
+[Baixe o Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) e descompacte, ou use `git clone`.
+**Windows:** dê dois cliques em `START-HERE.bat`. **Linux:** execute `./setup.sh` na pasta do Strata.
+
+**Mac (Apple Silicon, macOS 15 ou mais novo):** instale uma vez as Command Line Tools da Apple com `xcode-select --install`
+(o Xcode em si não é necessário). Abra o Terminal na pasta do Strata e execute `./setup.sh`. Ele compila o mecanismo do Mac no seu
+Mac (cerca de 7 minutos), faz as mesmas perguntas, baixa o modelo e inicia. Da próxima vez, `./setup.sh` inicia
+na hora. Qual tamanho cabe no seu Mac: [docs/MAC.md](docs/MAC.md).
+
+O instalador encontra a sua placa e configura o mecanismo certo. Ele pergunta qual modelo e tamanho, quanto contexto (quanto texto
+o modelo mantém em mente) e se deve ler imagens. Pressione Enter para aceitar a resposta recomendada. Depois ele baixa o
+modelo (cerca de 70 GB) e inicia. Se o download parar, execute de novo e ele continua. O navegador abre a página do Strata em
+`http://127.0.0.1:8080`.
+
+> Enquanto o modelo inicia, o seu PC pode ficar lento ou parar de responder por 1 a 3 minutos (mais tempo na primeira vez). O Strata carrega
+> de 35 a 55 GB na sua RAM e trava parte dela para a placa de vídeo. Espere e não feche a janela.
+
+Da próxima vez, execute `START-HERE.bat` (ou `./setup.sh`) de novo. Ele inicia na hora e não baixa nada duas vezes. Feche a janela
+dele para parar o modelo. `UPDATE.bat` (`./update.sh`) atualiza o Strata sem iniciá-lo. Atualização, Docker, várias placas,
+onde ficam os arquivos e todas as opções: [docs/INSTALL.md](docs/INSTALL.md).
+
+Para medir o seu PC, execute `BENCH.bat` (`./bench.sh`). Leva de 5 a 10 minutos e gera um relatório que você pode compartilhar
+([como](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)).
+
+**Opcional: mais velocidade numa placa quando o modelo inteiro cabe na RAM.** Duas configurações opcionais do RubenTorney (#1904, #1905).
+Elas ajudam quando você usa uma placa de vídeo e a sua RAM comporta todos os experts, por exemplo Q2_0 ou IQ3_XXS num PC de 64 GB. Abra
+`strata-<model>.json` na pasta de dados do Strata ([onde fica](docs/INSTALL.md#where-things-are-stored)) e adicione:
+
+- `"--adapt-async", "1"` à lista `"args"`. O cache de experts passa a ser atualizado numa thread auxiliar, em vez de pausar a
+  resposta. Medido numa RTX 5070 (Windows, Q2_0): +4 a 5% na geração, +7 a 10% em código e documentos longos. As respostas podem diferir
+  um pouco do padrão e continuam iguais de uma execução para outra.
+- `"STRATA_PIN_BY_NEED": "1"` no bloco `"env"` (Windows). O Windows só consegue travar cerca de metade da RAM para a placa
+  de vídeo, e isso trava primeiro os experts de que a placa precisa. Medido na RTX 5070: +4,4% na leitura do prompt.
+
+```json
+"args": [ ..., "--adapt-async", "1" ],
+"env": { "STRATA_PIN_BY_NEED": "1" }
+```
+
+Reinicie o Strata depois da alteração. Para desfazer, remova as duas entradas.

 ## Como funciona?

-Modelos como este normalmente rodam em servidores com centenas de gigabytes de memória de vídeo. Sua placa de vídeo
-tem 12-24 GB. O Strata faz o modelo caber **dividindo o trabalho pelo PC inteiro**. Pense numa cozinha: o que você
-usa o tempo todo fica na bancada, e o resto espera na despensa.

+- **A sua placa de vídeo é a mesa.** Ela é pequena e rápida. Os cerca de 4.000 livros mais usados ficam abertos nela.
+- **A sua RAM são as estantes da sala de leitura.** Os 24.576 livros estão lá. Quando uma palavra precisa de um livro que não está na
+  mesa, o seu processador lê da estante na hora, enquanto a placa continua trabalhando.
+- **O seu SSD é o arquivo.** Ele guarda uma tabela de consulta de 29 GB. O modelo lê algumas linhas dela por palavra, então ela não
+  precisa ficar na RAM.

-## 你需要什么
-
-| | |
+| 你的电脑 | 说明 |
 | --- | --- |
-| **显卡** | **NVIDIA** GeForce RTX 20、30、40 或 50 系列，或 **AMD** Radeon RX 7900 XT / XTX、RX 7800 XT / 7700 XT、RX 9060 XT、RX 9070 / 9070 XT、Radeon AI PRO R9700 或 RX 6800 / 6900 系列。需要 **12 GB 或以上显存**。 |
-| **内存** | 32 GB 或以上。内存大小决定能装下[哪个模型](#该选哪个模型)。64 GB 可以运行所有规格。 |
-| **硬盘** | 约 80 GB 可用空间。尽量用 SSD：第一次启动会快很多。 |
-| **系统** | Windows 10 / 11 或 Linux，以及 NVIDIA 或 AMD 的最新显卡驱动。 |
+| **NVIDIA** GeForce RTX 20、30、40、50 系列（12 GB 及以上） | 安装应用或终端版即可。 |
+| **AMD** Radeon RX 6800 及更新型号、Radeon AI PRO R9700（12 GB 及以上） | [AMD 显卡](docs/AMD_HIP.md) |
+| **Intel** Arc | [Intel Arc](docs/INTEL_ARC.md)、[Intel 引擎](docs/INTEL.md) |
+| **Apple 芯片 Mac**（M1 及更新，macOS 15 及以上） | [Mac](docs/MAC.md) |

-
-完整列表：[docs/INSTALL.md](docs/INSTALL.md#what-you-need)。
+同一品牌的两三张显卡可以共同运行一个模型（[多显卡](docs/MULTI_GPU.md)）。Strata 不会把一个模型拆到 NVIDIA 和 AMD
+显卡上。完整列表见 [docs/INSTALL.md](docs/INSTALL.md#what-you-need)。

 ## 安装

-### 让你的 AI 帮你装
+三种方式任选一种。它们启动的是同一个引擎，用的是同样的模型。

-你在用 AI 编程助手吗（Claude Code、Cursor、Codex、GitHub Copilot 等）？把下面这段粘贴给它：
+### 方式 A：Strata 应用
+
+最简单的方式。应用内置引擎：安装、选模型、开始聊天。请根据你的系统和显卡，从
+[发布页](https://github.com/Niko1221/Strata/releases/latest)下载对应的文件。不确定选哪个？看表格下面那一段。
+
+| 系统 | 你的显卡 | 要下载的文件 |
+| --- | --- | --- |
+| **Windows 10 / 11** | NVIDIA RTX，驱动 580 或更新 | [`Strata-0.2.3-windows-cuda13.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda13.exe) |
+| | NVIDIA，较旧的显卡，或驱动低于 580 | [`Strata-0.2.3-windows-cuda12.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-cuda12.exe) |
+| | AMD Radeon RX 9000 系列或 Radeon AI PRO R9700 | [`Strata-0.2.3-windows-hip.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip.exe) |
+| | AMD Radeon RX 7000 系列或 Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-windows-hip-rdna3.exe`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-windows-hip-rdna3.exe) |
+| **Linux** | NVIDIA RTX，驱动 580 或更新 | [`Strata-0.2.3-linux-nvidia-cuda13.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda13.AppImage) |
+| | NVIDIA，较旧的显卡，或驱动低于 580 | [`Strata-0.2.3-linux-nvidia-cuda12.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-nvidia-cuda12.AppImage) |
+| | AMD Radeon RX 9000 系列或 Radeon AI PRO R9700 | [`Strata-0.2.3-linux-amd-rx9070.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx9070.AppImage) |
+| | AMD Radeon RX 7000 系列 | [`Strata-0.2.3-linux-amd-rx7900.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-rx7900.AppImage) |
+| | AMD Ryzen AI Max (Strix Halo) | [`Strata-0.2.3-linux-amd-strixhalo.AppImage`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-linux-amd-strixhalo.AppImage) |
+| **Mac**（Apple 芯片，macOS 15 及以上） | 内置 | [`Strata-0.2.3-mac.dmg`](https://github.com/Niko1221/Strata/releases/latest/download/Strata-0.2.3-mac.dmg) |
+
+**不确定时：** NVIDIA 显卡的驱动版本在 580 及以上就选 `cuda13`，否则选 `cuda12`。`cuda12` 适用于较旧的显卡和驱动。
+`hip` 和 `amd` 的文件是给 AMD 显卡用的。其他 AMD 显卡（RX 6000）目前还没有现成的应用，
+请看 [AMD 显卡](docs/AMD_HIP.md)。
+
+然后：
+
+- **Windows：** 运行 `.exe`。它只为当前用户安装，不需要管理员权限。如果 Windows 提示“Windows 已保护你的电脑”，
+  点击**更多信息**，再点**仍要运行**（安装程序还没有代码签名）。
+- **Linux：** 给文件加上可执行权限（`chmod +x`），然后启动。需要 FUSE 2：`sudo apt install libfuse2`（Ubuntu 22.04），
+  或 `libfuse2t64`（Ubuntu 24.04 及更新）。
+- **Mac：** 打开 `.dmg`，把 Strata 拖到“应用程序”。
+
+第一个界面里，应用会检测你的电脑，并推荐合适的模型。点击安装即可。模型很大，要下载约 40-70 GB，中断后会从断点继续。
+关闭窗口会同时停止 Strata 和引擎。
+
+### 方式 B：终端（一行命令）
+
+终端版就是 `strata` 命令，适合脚本、服务器和 AI 智能体。
+
+Linux 和 Mac：
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+```
+
+Windows（PowerShell）：
+
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+脚本会检查你的电脑，下载终端版，校验 SHA-256，然后解压到你的用户目录。不需要管理员权限。在 Windows 上，装完后请
+打开一个新的终端窗口。然后启动 Strata：
+
+```sh
+strata launch
+```
+
+它会一次问一个问题：模型、上下文、图片、允许谁连接。接着为你的显卡下载引擎（已签名，使用前会先试启动），再下载
+模型，并开始提供服务。在脚本和 AI 智能体里，请使用参数：
+
+```sh
+strata launch --model q2_0 --yes --no-tui
+```
+
+如果想在运行前先看看安装脚本，先用 `curl -fsSL <address> -o install.sh` 下载，读完后再用 `sh install.sh` 运行。
+所有界面和参数见 [docs/TERMINAL_LAUNCH.md](docs/TERMINAL_LAUNCH.md)。
+
+### 方式 C：让你的 AI 来安装
+
+把下面这段话粘贴到 Claude Code、Cursor、Codex、GitHub Copilot 或其他编程助手里：

 ```text
 Set up Strata on this PC for me: https://github.com/Niko1221/Strata - follow docs/AI_SETUP.md in that repository.
 ```

-它会检查你的显卡、内存和硬盘，选出合适的模型。然后安装并启动它，再告诉你怎么连接你的应用。AI 工具也可以通过
-Strata 的 [MCP 服务器](docs/MCP_SERVER.md)来安装、启动和停止 Strata。
+它会检查你的显卡、内存和磁盘，选出合适的模型，完成安装和启动，并告诉你怎么连接你的应用。AI 工具也可以通过 Strata 的
+[MCP 服务器](docs/MCP_SERVER.md)安装、启动和停止 Strata。

-### 或者自己动手
+想自己动手编译？请看[从源码构建](#从源码构建)。

-[下载 Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip) 并解压（或者用 `git clone`）。
-**Windows：** 双击 **`START-HERE.bat`**。**Linux：** 在 Strata 文件夹里运行 **`./setup.sh`**。
+## 模型

-NVIDIA 和 AMD 的步骤完全一样。安装程序会识别你的显卡，并装好对应的引擎。它会问你几个问题：
+应用和 `strata launch` 会按你的内存推荐模型。它是同一个模型的几种尺寸，压缩程度不同。尺寸小的更快，尺寸大的稍微更聪明一点。

- 用哪个模型、哪个规格，
- 上下文多大（模型能记住多少文字），
- 是否要识别图片。
+### 内存不够？试试 Gyro

-每次直接按回车就是推荐选项。之后它会下载模型（约 70 GB）并启动。如果下载中断了，再运行一次即可：它会从中断的地方继续。
-浏览器会打开 Strata 应用，地址是 `http://127.0.0.1:8080`。
+[Gyro](https://huggingface.co/agentionai/Qwen3.8-Flash-Next-Gyro-GGUF)（作者 agentionai）是运行这个模型占用最小的方式。

-> **模型启动时，你的电脑可能会变慢或卡住 1-3 分钟**（第一次最久）。
-> Strata 会把 35-55 GB 加载到内存，并为显卡锁定其中一部分。这是正常的。请耐心等待，不要关闭窗口。
-> 窗口里会显示 Strata 正在做什么。
+| 尺寸 | 所需内存（RAM + VRAM） | 下载大小 | 说明 |
+| --- | ---: | ---: | --- |
+| **Gyro-S** | 27.6 GB | 58.5 GB | 给其他尺寸都放不下的电脑。质量低于 IQ2_XS。 |
+| **Gyro-M** | 35 GB | 92.0 GB | 质量约相当于 IQ3_XXS，显存占用少约 20%。输出回答比 Q2_0 慢，12 GB 的 RTX 3060 上慢 16%，R9700 上慢 21%。 |

-**下次使用时**，再运行一次 `START-HERE.bat`（或 `./setup.sh`）。它会马上启动，已下载的东西不会重复下载。关闭它的窗口就能停止模型。
-`UPDATE.bat`（`./update.sh`）只更新 Strata，不启动。更新、Docker、多张显卡、文件存放位置以及所有选项：
-[docs/INSTALL.md](docs/INSTALL.md)。
+Gyro 可在 NVIDIA 和 AMD 显卡（AMD 为实验性支持）以及 Linux 上的 Intel Arc 显卡（已在 Arc A750 上测试）上运行，自 0.2.2 起也可在 Apple Silicon 的 Mac 上运行（32 GB 的 Mac mini 上 Gyro-S 为 9 token/秒，专家权重从 SSD 读取）。详情和测试数据：
+[docs/GYRO.md](docs/GYRO.md)。用 `strata launch --model gyro-s` 启动。

-## 该选哪个模型
+### 其他尺寸

-安装程序会根据你的内存推荐一个。同一个模型有几种规格，压缩程度不同。规格越小越快，越大越聪明一些。
-
-| 你的内存 | 选择 | 原因 |
+| 你的内存（RAM + VRAM） | 选择 | 备注 |
 | --- | --- | --- |
-| **32 GB** | **Coder** | 32 GB 装得下，而且专为代码打造（如果显卡是 24 GB，Q2_0 和 IQ2_XS 也能跑） |
-| **48 GB** | **IQ2_XS**（或 Q2_0，最快） | 更大的规格装不下 |
-| **64 GB** | **IQ2_XS**（推荐），或 IQ3_XXS / IQ3_S | 所有规格都装得下；IQ3_S 最好，也最慢 |
-| **96 GB 或以上** | **IQ3_S**，或 Unsloth 的 UD-IQ4_XS（约 4-bit） | 开着其他程序也能放下最大的规格 |
+| **32 GB** | **Gyro-S**，写代码可选 **[Coder](docs/MODELS.md#coder)** | Coder 需要 32 GB 内存，只保留一半的专家，所以代码以外的能力较弱 |
+| **40 GB** | **[Swift 1.5](docs/MODELS.md#swift-15)** IQ2_XS（39.2 GB），或 **Gyro-M**（35 GB） | Swift 回答前思考的时间更短。Gyro-M 的质量接近 IQ3_XXS，但输出回答比 Q2_0 慢 16-21% |
+| **48 GB** | **IQ3_XXS**（47.0 GB） | 更慢，更好 |
+| **64 GB** | **IQ3_S**（54.8 GB），原版或 Swift 1.5 | 最慢，最好：在公开测试中与完整模型持平 |
+| **96 GB 及以上** | Unsloth 的 **UD-IQ4_XS**（约 72 GB 内存）到 **Q8_0**（约 136 GB），4 到 8 位 | 更接近完整模型。内存不足时，Strata 会从固态硬盘读取一部分，速度会慢很多 |

- **[Coder](docs/MODELS.md#coder)：** 编程版本，去掉了一半专家。它达到完整模型 SWE-bench Verified 分数的 91%（由其作者测得），
-  32 GB 内存就能装下。代码以外的能力较弱，包括中文和其他中日韩文本（#438）。这类用途请选 Q2_0、IQ2_XS 或 IQ3_S，
-  它们保留了所有专家。
- **[Swift 1.5](docs/MODELS.md#swift-15)：** 一个微调版本，回答前思考的时间短得多。你能更早拿到答案，质量基本不变。
- **[Unsloth UD-IQ4_XS](docs/MODELS.md#unsloth-ud-iq4_xs)：** Unsloth 的约 4-bit 版本，质量介于 IQ3_S 和 UD-Q4_K_XL 之间。
-  下载 94 GB。内存少于约 80 GB 时，Strata 回答时要从 SSD 读取其中一部分，所以会更慢（NVMe SSD 有帮助）。
- **[Unsloth UD-Q4_K_XL](docs/MODELS.md#unsloth-ud-q4_k_xl-experimental)**（实验性）：最接近完整模型。但 Strata
-  回答时要从 SSD 读取其中大部分内容，所以在 64 GB 的电脑上每秒只能写 7-8.5 个 token。
- **[OrcaRouter 的 Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs)：** 需要手动设置，不在安装程序的菜单里。
+内存比这一行写的少，也可能能用：Strata 会自动切换到[低内存模式](docs/MODELS.md#a-big-graphics-card-and-little-ram)。
+速度会变慢，显卡较小时会慢得多。

-规格、下载以及各配置能装下什么：[docs/MODELS.md](docs/MODELS.md)。以后想再添加模型，运行
-`SETUP.bat`（Linux：`./setup.sh --setup`）。
+更多选择：
+
+- **[Swift 1.5](docs/MODELS.md#swift-15)** 是微调版本，回答前思考的时间更短，质量和内存占用大致相同。
+- **[NVFP4](docs/NVFP4.md)** 是 NVIDIA 为 NVIDIA 显卡提供的 4 位版本。要把所有专家放进内存，需要约 80 GB 内存。
+- **[Qwen3.6-35B-A3B](docs/QWEN36.md)** 是另一个更小的模型，能看图片，还能同时回答多个请求。
+- **[OrcaRouter 的 Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs)** 需要手动设置。
+
+所有尺寸、下载大小，以及各种配置能跑什么：[docs/MODELS.md](docs/MODELS.md)。
+
+### DeepSeek V4.1-Flash（终端版，0.2.4 起）
+
+[DeepSeek V4.1-Flash](https://huggingface.co/ISTA-DASLab/DeepSeek-V4.1-Flash-1017-GSQ-RCO-GGUF) 是另一个大得多的模型。下面三个版本由 ISTA-DASLab 制作。Strata 在一台有一块 12 GB 显卡和 46 到 64 GB 内存的电脑上运行它们，其余部分从固态硬盘读取。它可在 NVIDIA RTX 30 到 50 系列显卡和 Radeon AI PRO R9700 上运行。它使用自己的引擎包 `strata-dsv41`，你选择 DeepSeek 时由 `strata launch` 下载。桌面应用暂时不提供它。
+
+| 版本 | 下载大小 | 与原模型相比的质量 | 生成速度 |
+| --- | ---: | --- | --- |
+| **IQ1_M**（1.75 位） | 239 GB | KL 0.217，困惑度 3.80（+21%）；代码 +8.9%，智能体任务 +10.2%；普通英文散文表现较弱。据 ISTA-DASLab 的模型卡，它保留了基础模型任务平均分的 98.7%（AIME25、GPQA-Diamond、LiveCodeBench v6）。 | 尚未测量 |
+| **IQ2_XXS** (2.00 位) | 257 GB | KL 0.170，困惑度 3.63（+15.5%）；代码 +8.6%，智能体任务 +5.3% | RTX 3060 上每秒 6 到 9 个 token，RTX 5070 上约 5 个 |

-<sub>Strata 应用的 <b>Monitor</b>（左），编程智能体正在写视频里的宝塔花园（右）</sub></p>
+### 在应用里

- **在浏览器里：** 打开 `http://127.0.0.1:8080`。里面有 **Chat**（聊天）、实时 **Monitor**（监控模型和你的
-  GPU/CPU/内存），以及 **About**（设置和地址）。
- **你的应用和编程智能体：** 添加一个“OpenAI 兼容”的提供商，base URL 填 **`http://127.0.0.1:8080/v1`**。
-  API key 和模型名随便填都行。
-  - 使用 Anthropic API 的应用：`http://127.0.0.1:8080/v1/messages`（Claude Code：
-    `ANTHROPIC_BASE_URL=http://127.0.0.1:8080`）。
-  - Codex CLI 和其他使用 OpenAI Responses API 的应用：`/v1/responses`
-    （[设置方法](docs/DETAILS.md#the-responses-api-and-codex-cli)）。
- **思考：** 在聊天菜单或应用的“reasoning effort”里选择 **off、low、medium 或 high**。off 最快，
-  high 最适合难题。
- **图片：** 在安装时对“Images?”选是。然后在聊天里点 **Picture**，或在你的应用里附上图片。
-  AMD 显卡在 Linux 上通过处理器识别图片；在 Windows 上暂时还不行。
- **从手机或另一台电脑访问：** `START-HERE.bat --setup --host 0.0.0.0 --api-key <secret>`。一定要设置 key。
- **一次处理一个请求：** 默认情况下 Strata 一次只回答一个请求，其他请求排队等待。想同时回答多个，
-  设置 `"parallel": 2`（[BATCHING.md](docs/BATCHING.md)）。在 12 GB 显卡上，这会让每个回答变慢。
- **长提示：** Strata 会完整读入对话的第一条消息，大约每 30,000 个 token 需要 1 分钟。之后的消息几秒内就开始回答。
+应用包含**聊天**、显示模型以及 GPU、CPU 和内存状态的**监控**、**模型**页面和**设置**。聊天可以在你电脑上的某个文件夹里工作。
+在**手动**模式下，修改文件或运行命令之前它会先询问你。输入 `/loop 10m <要做的事>`，在聊天保持打开期间每 10 分钟重复发送一次消息。

+
+`strata connect` 会打印 OpenCode、Codex CLI、Claude Code、oh-my-pi、pi、Hermes Agent 和 OpenClaw 的具体设置。
+`strata connect opencode --write` 会在询问后写入配置文件，并保留备份。
+
+### 图片
+
+能看图片的模型默认开启图片功能。在聊天里附加或粘贴图片，或者从你的应用发送图片。显卡的显存小于 24 GB 时，读图由处理器完成
+（每张图片几秒钟，不占用显卡的显存）；显存达到 24 GB 时，由显卡完成。NVIDIA 和 AMD 的规则相同。你可以按模型关闭图片功能，
+也可以用 `--vision off`、`--vision gpu` 或 `--vision cpu` 选择读图方式。
+
+这条规则背后的数据：在 Radeon AI PRO R9700 上，显卡读一张 260 token 的图片用了 57 ms，处理器用了 3.1 秒。在 16 GB 的显卡
+（Tesla P100 和 RTX A4000，Linux）上，用显卡读图会让文字速度下降 3-5%，因为它占用约 1.4 GB 显存，否则这部分会被模型使用。
+在 Mac 上，无论内存多大，都由 GPU 读图（32 GB 的 M4 上读一张 260 token 的图片用 0.45 秒，占用约 1.2 GB 共享内存）；处理器读一张约需 50 秒，所以只有指定 `--vision cpu` 时才用。
+
+### 使用须知
+
+- 在聊天菜单或你的应用的“reasoning effort”里选择思考级别（**off、low、medium 或 high**）。off 最快。
+- Strata 默认一次回答一个请求。要同时处理多个，请在 `strata launch` 中使用 `--parallel N`，或在配置里写
+  `"parallel": 2`（[BATCHING.md](docs/BATCHING.md)）。在 12 GB 显卡上，这会让每个回答变慢。
+- Strata 会完整读取聊天的第一条消息，每 30,000 个 token 约需 1 分钟。之后的消息几秒钟就开始。

+
+[下载 Strata](https://github.com/Niko1221/Strata/archive/refs/heads/main.zip)并解压，或者用 `git clone` 获取。
+**Windows：** 双击 `START-HERE.bat`。**Linux：** 在 Strata 文件夹里运行 `./setup.sh`。
+
+**Mac（Apple 芯片，macOS 15 及以上）：** 先用 `xcode-select --install` 安装一次 Apple 的命令行工具（不需要完整的 Xcode）。
+在 Strata 文件夹里打开终端，运行 `./setup.sh`。它会在你的 Mac 上构建 Mac 引擎（约 7 分钟），问同样的问题，下载模型并启动。
+下次运行 `./setup.sh` 会直接启动。你的 Mac 适合哪个尺寸：[docs/MAC.md](docs/MAC.md)。
+
+安装程序会找到你的显卡，并设置合适的引擎。它会问你用哪个模型和尺寸、上下文多长（模型能记住多少文字），以及是否要读取图片。
+直接按回车就是推荐的选择。然后它会下载模型（约 70 GB）并启动。如果下载中断，再运行一次就会继续。浏览器会打开
+`http://127.0.0.1:8080` 上的 Strata 页面。
+
+> 模型启动期间，你的电脑可能会变慢，或者在 1-3 分钟内没有响应（第一次最久）。Strata 会把 35-55 GB 加载到内存里，并锁定其中一部分
+> 给显卡使用。请等待，不要关闭窗口。
+
+下次再运行 `START-HERE.bat`（或 `./setup.sh`）会立即启动，不会重复下载。关闭它的窗口就能停止模型。`UPDATE.bat`
+（`./update.sh`）只更新 Strata，不启动。更新、Docker、多显卡、文件存放位置和所有选项：[docs/INSTALL.md](docs/INSTALL.md)。
+
+要测试你的电脑，运行 `BENCH.bat`（`./bench.sh`）。需要 5-10 分钟，并生成一份可以分享的报告
+（[方法](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)）。
+
+**可选：整个模型都放得进内存时，让单卡更快。** 这是 RubenTorney 提供的两个需要手动开启的设置（#1904、#1905）。
+当你只用一张显卡，并且内存装得下所有专家时，它们会有帮助，例如在 64 GB 的电脑上跑 Q2_0 或 IQ3_XXS。打开 Strata 数据文件夹里的
+`strata-<model>.json`（[位置](docs/INSTALL.md#where-things-are-stored)），然后添加：
+
+- 在 `"args"` 列表中加入 `"--adapt-async", "1"`。这样专家缓存会在辅助线程上更新，不会让回答暂停。在 RTX 5070
+  （Windows，Q2_0）上测得：解码快 4-5%，代码和长文档快 7-10%。回答可能与默认设置略有不同，但每次运行的结果保持一致。
+- 在 `"env"` 块中加入 `"STRATA_PIN_BY_NEED": "1"`（Windows）。Windows 只能为显卡锁定大约一半的内存，
+  这个设置会优先锁定显卡最先需要的专家。在 RTX 5070 上测得：读取提示词快 4.4%。
+
+```json

+可以把它想成一座图书馆。
+
+- 模型是一个由 24,576 位小专家（“experts”）组成的团队，好比 24,576 本参考书。每个词只需要其中 10 本。
+- **你的显卡是书桌。** 它小而快。最常用的大约 4,000 本书摊开放在上面。
+- **你的内存是阅览室的书架。** 24,576 本书都在这里。某个词需要一本不在书桌上的书时，处理器会立刻从书架上取来读，显卡则继续工作。
+- **你的固态硬盘是档案室。** 里面存着一张 29 GB 的查找表。模型每个词只读其中几行，所以不用常驻内存。

+
+另外有一个小助手会猜接下来的几个词。大模型一次检查所有猜测，保留正确的部分。得到的答案不变，但快了 1.6-1.8 倍。

+
+## The desktop app and the Terminal
+
+Strata comes in three parts that share one engine: the **desktop app**, the **Terminal** (`strata`) and the **engine** that runs
+the model. The section above is about the engine's HTTP server. This is what the other two add.
+
+- **The app's host listens on this PC only.** The app serves its page from a local host process on `127.0.0.1` (port 8791 unless
+  changed). A request to its `/api/` endpoints that carries a browser `Origin` from any other site gets 403. The app shell holds a
+  random secret (32 characters or more, compared in constant time) that is needed to quit the host or tell it which window is open,
+  and the host gives its own helper processes a second random secret. By default the models the app starts are served on this PC only.
+- **Sharing is a separate, key-protected listener.** "Share with other devices" (and the Cloudflare tunnel) will not start until an
+  API key is set. It opens a different listener that answers only `/v1/models`, `/v1/chat/completions` and `/v1/messages`, never the
+  app's page or its host endpoints.
+- **App and Terminal talk through an owner channel.** One owner process per installation starts and ends the engine, and a second
+  client (the Terminal) attaches to it. On macOS and Linux that is a private Unix socket in a folder only you can open. On Windows it
+  is a TCP listener on `127.0.0.1` that answers only requests carrying a 256-bit token kept in an owner-only folder. That is a weaker
+  guarantee than a socket other users cannot open: on Windows the token is what protects it, as with any loopback service that has a
+  token (`strata_control/owner_transport.py`). The bridge between the app shell and the host (used for the app update) is also loopback and protected by a token.
+- **Starting a model and serving never download anything.** Downloads and updates are one explicit step: `strata update`, or "Update
+  engine" and "Update Strata" in the app's Settings. Models and saved tuning are never replaced by an update.
+- **Updates come from a signed feed.** The release publishes `strata-feed.json` and `strata-feed.json.sig` (Ed25519). An installed
+  Strata checks the signature against the public key it carries (`strata_control/update_keys.json`), refuses a feed older than the last
+  one it accepted (a replayed old feed) or expired, and checks every engine package against its SHA-256, its signed manifest and the
+  card in your PC before it test-starts it and switches to it. Any failure keeps the engine you had. The app installer itself is signed
+  with a separate key (Tauri's minisign key) that the app and the Terminal both check. The private keys are kept offline by the owner.
+  See [packaging/UPDATES.md](packaging/UPDATES.md).
+
+### How far to trust `curl | sh` and `irm | iex`
+
+The Terminal installs with one line:
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh | sh
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
+```
+
+Piping a script into a shell runs whatever the server sends, so it deserves the same care as running any downloaded program.
+What the script does is short and written at its top: it fetches the Terminal archive named in the release's `install-manifest.txt`,
+checks its SHA-256, unpacks it into your home folder (no administrator rights, nothing outside your home), checks the release's signed feed
+with the Terminal it just unpacked and removes it again if that fails, and puts `strata` on your PATH.
+
+Those checks have a limit. The checksum comes from the same release as the archive, and the public key that checks the feed arrives inside
+that archive, so for the first install all trust rests on HTTPS and on the `Niko1221/Strata` GitHub release itself. The checks catch a
+damaged or half-finished download and a feed that was not signed by the release key; they do not protect you if the release has been replaced
+by someone who controls it. Later updates are checked against the key already on your PC, which is a stronger position.
+
+If that is not enough: save the script (`curl -fsSLO https://github.com/Niko1221/Strata/releases/latest/download/install.sh`), read it, and
+run it from the file; or install the desktop app or build from source instead and check the code you build.

 Strata has not had an outside security audit yet.
+What Strata downloads, when it uses the internet, what stays on your PC and how downloads are checked is written up in [docs/SAFETY.md](docs/SAFETY.md).

+
+    python apps/desktop/scripts/app-close-matrix.py --install <folder the installer wrote> [--scenarios all] [--report out.json]
+
+For each case it starts the REAL installed `strata-desktop.exe` (its window opens), loads a stub engine through the host's API
+(profile + `runtime start` under Control's owner runtime, exactly the app's path), records every process of the tree (the app,
+the host, Control, the owner host, the server, the engine), ends the app one way, and asserts:
+  * no process of the tree is left, the engine's port is free, the runtime lease can be taken again;
+  * the engine got the clean stop where the way of closing allows one (normal close, window X);
+  * the next load of the same slot works (a lost owner's state is cleaned, not a blocker).
+It also proves a second launch focuses the open window and starts nothing, and that one app runs two engines and closes both.
+Everything per-user lives under a scratch folder; the stub engine is a script. No real engine ever runs.

+ * Attached pictures reaching a model, end to end on a test box, through the installed app layout (packaged host + bundled Control + an engine
+ * component that carries strata-vision):
+ *   1. the model catalog marks the picture-capable models (images: true) when the picture reader is installed;
+ *   2. API models: a llama-server with a small picture model (--mmproj) is saved as a Custom model API; the host works out that it reads pictures,
+ *      and a real picture goes out as image_url and is answered. A server without a picture reader, a model set "not to read pictures", and an API
+ *      of another style each get a plain refusal (409) that says how to fix it; ticking "This model reads pictures" lets the picture through;
+ *   3. a local model (unless --skip-local): Download and prepare with Read pictures ON, load, and a picture through the app's own chat.
+ *
+ *   node pics-e2e.mjs --install <node/ host/ control/> --components <engine components> --work <scratch> --image shapes.png \
+ *   Also: --silent <url> (a server whose model list says nothing about pictures: ON by default), --agent (the same picture through the agent; needs a Harness)
