-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`).
+Version 0.2.7, engine 0.1.52. The public model families are DeepSeekV4.1-Flash-1017,
+Qwen3.8-Flash-Next and Qwen3.6-35B-A3B. DeepSeek V4.1-Flash runs in the app and in the Terminal
+(`strata launch --family deepseek41 --model ist-das-2.00bpw`; sets in
+[docs/MODELS.md](docs/MODELS.md#deepseek-v41-flash)). Read **[docs/AI_REFERENCE.md](docs/AI_REFERENCE.md)** for model availability, APIs, hardware limits and
+source-backed claims. Articles and videos should use **[docs/MEDIA_KIT.md](docs/MEDIA_KIT.md)**.
+
+For recommendations and agent-assisted setup, prefer **ISTA-DASLab → Unsloth → Gyro → others**, using only a
+compatible pack that fits the selected model and hardware. ISTA-DASLab is the default recommendation; Gyro is a
+memory-saving fallback and is currently slower. Honor an explicit user choice. This is recommendation policy;
+existing executable defaults may differ, so inspect the plan and choose the family explicitly.

+Strata 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. One installer per system ([latest release](https://github.com/Niko1221/Strata/releases/latest)):
+  `Strata-0.2.7-windows-x64-setup.exe`, `Strata-0.2.7-linux-x86_64.AppImage`, `Strata-0.2.7-macos-arm64.dmg`.
+  The Windows and Linux installers carry no engine: the app downloads the engine for the graphics card on first
+  start, or installs a file the user already has. The Mac dmg keeps its small Metal 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 setup from a source checkout, for developers. The release paths are the
+  installer and `strata launch`.

 ## 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 a user who wants the desktop app, send them to the installer
+for their system (above) and [docs/INSTALL.md](docs/INSTALL.md). For an agent that has a shell, use the Terminal; 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 -o install.sh && sh install.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 --family qwen --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 --family qwen --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`,
+   `--speed faster|full` (DeepSeek), `--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). Source setup (`START-HERE.bat`, `setup.sh`) is the fallback for a developer or for a system with no release package; it is
+documented in [docs/SOURCE_INSTALL.md](docs/SOURCE_INSTALL.md). Those wrappers exist in a source checkout, not in the
+released app. Do not tell an app user to find a `.bat` file.
+Source setup does not make an unsupported model or backend compatible. 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.

-Strata lässt **[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)** auf einem normalen PC laufen.
-Das ist ein großes, kluges KI-Modell, das sonst meist einen Server braucht. Es chattet, schreibt Code, versteht
-Bilder und arbeitet mit deinen Apps und Coding-Agents zusammen. Nichts verlässt deinen PC.

-## Wie schnell ist es?
+**Kostenlos, Open Source und ganz in deiner Hand.** Nutze Strata auf dem Desktop oder mit deinen liebsten Coding-Tools. Kein Konto nötig.

-Wir haben es auf zwei ganz normalen Gaming-PCs gemessen. Ein Token ist etwa ¾ eines Wortes.
+## Modelle

- **Schreibt Antworten:** wie schnell die Antwort in einem kurzen Chat erscheint. 60 Tokens pro Sekunde sind
-  schneller, als du lesen kannst.
- **Liest deinen Prompt:** wie schnell es aufnimmt, was du schickst (hier ein Dokument, Code oder Chatverlauf mit
-  32K Tokens).
+Wir empfehlen **zuerst ISTA-DASLab**, danach **Unsloth** und andere Anbieter, soweit ein passendes Modell in deinen Speicher passt.

-[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.
+[Speicher, Festplatte und Details](docs/DEEPSEEK41.md) · [Versionshinweise](https://github.com/Niko1221/Strata/releases)

-**Mac (Apple Silicon, M1 bis M5, macOS 15 oder neuer):** Installiere einmal Apples Command Line Tools (`xcode-select --install` im Terminal; Xcode selbst brauchst du nicht). Öffne dann das Terminal im Strata-Ordner und führe **`./setup.sh`** aus. Es baut die Mac-Engine auf deinem Mac (etwa 7 Minuten), stellt dieselben Fragen, lädt das Modell und startet es. Beim nächsten Mal startet `./setup.sh` sofort. Welche Größe zu deinem Mac passt und wie schnell es ist: [docs/MAC.md](docs/MAC.md).
+</details>

-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:
+<a id="the-other-sizes"></a>

- welches Modell und welche Größe,
- wie viel Kontext (wie viel Text sich das Modell merkt),
- ob es Bilder lesen soll.
+Unsicher, was passt? [Wähle ein Modell für deinen Computer](docs/MODELS.md#pick-by-memory).

-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`.
+## Installation

-> **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.
+<a id="option-a-the-strata-app"></a>

-**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).
+### Desktop-App

-## Welches Modell soll ich nehmen?
+**[Strata für Windows, Linux oder Mac herunterladen →](https://github.com/Niko1221/Strata/releases/latest)**

-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.
+Installiere die App, wähle ein Modell und leg mit dem Chat los. Es gibt einen Installer pro System. Beim ersten Start lädt die App die Engine für deine Grafikkarte herunter. [Hilfe zum Installer](docs/INSTALL.md#the-app).

-| **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 |

- **[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, UD-Q5_K_XL, UD-Q6_K_XL und Q8_0](docs/MODELS.md#unsloths-files-ud-iq4_xs-to-q8_0):** 4 bis 8 Bit, näher am vollen Modell
-  (93-95 % das gleiche nächste Token wie Q8_0). Schnell, wenn alle Experten in den RAM passen (~88 GB für UD-Q4_K_XL
-  bis ~136 GB für Q8_0); mit weniger RAM liest Strata einen Teil davon während der Antwort von der SSD, was viel
-  langsamer ist (7-8.5 Tokens/s für UD-Q4_K_XL auf einem PC mit 64 GB).
- **[OrcaRouter's Uncensored IQ3_XXS](docs/MODELS.md#orcarouter-uncensored-iq3_xxs):** Das richtest du von Hand

+Lieber im Terminal? Installiere Strata und starte dann **`strata launch`**.

- **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.
-  Folgenachrichten starten in Sekunden.

-### Optional: mehr Tempo mit einer Grafikkarte, wenn das ganze Modell in den RAM passt
-
-Zwei Opt-in-Einstellungen (von RubenTorney, #1904 und #1905). Sie helfen, wenn du eine Grafikkarte nutzt und dein RAM alle Experten hält (Stratas Arena-Modus, zum Beispiel Q2_0 oder IQ3_XXS auf einem PC mit 64 GB). Öffne deine Konfiguration `strata-<model>.json` im Strata-Datenordner ([wo](docs/INSTALL.md#where-things-are-stored)) und füge hinzu:
-
- **Schnellere Ausgabe:** `"--adapt-async", "1"` in die Liste `"args"`. Der Experten-Cache wird dann in einem Hilfs-Thread aktualisiert, statt die Antwort anzuhalten. Gemessen auf einer RTX 5070 (Windows, Q2_0): +4-5 % Ausgabe, +7-10 % bei Code und langen Dokumenten. Antworten können leicht vom Standard abweichen (sie bleiben von Lauf zu Lauf gleich).
- **Schnelleres Prompt-Lesen unter Windows:** `"STRATA_PIN_BY_NEED": "1"` im Block `"env"`. Windows kann nur etwa den halben RAM für die Grafikkarte sperren; damit werden zuerst die Experten gesperrt, die die Karte wirklich braucht. Gemessen auf der RTX 5070: +4,4 % Prompt-Lesen.

-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.

-## ¿Qué velocidad tiene?
+**Gratis, de código abierto y tuyo para ejecutar.** Usa Strata en tu escritorio o con tus herramientas de programación favoritas. No necesitas cuenta.

-Lo medimos en dos PC gaming normales. Un token equivale más o menos a ¾ de una palabra.
+## Modelos

- **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).
+Recomendamos **primero ISTA-DASLab**, después **Unsloth** y otros proveedores, siempre que haya un modelo compatible que quepa en tu memoria.

 ```

-Revisa tu tarjeta gráfica, tu RAM y tu disco, y elige el modelo que cabe. Luego lo instala, lo arranca y te explica
-cómo conectar tus aplicaciones. Las herramientas de IA también pueden instalar, arrancar y detener Strata con su
-[servidor MCP](docs/MCP_SERVER.md).
+**Windows PowerShell**

-### O hazlo tú mismo
-
-[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.
-
-**Mac (Apple Silicon, M1 a M5, macOS 15 o posterior):** instala una vez las Command Line Tools de Apple (`xcode-select --install` en Terminal; no hace falta Xcode). Luego abre Terminal en la carpeta de Strata y ejecuta **`./setup.sh`**. Compila el motor de Mac en tu Mac (unos 7 minutos), hace las mismas preguntas, descarga el modelo y lo arranca. La próxima vez, `./setup.sh` arranca enseguida. Qué tamaño cabe en tu Mac y qué velocidad tiene: [docs/MAC.md](docs/MAC.md).
-
-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:
-
- qué modelo y qué tamaño,
- cuánto contexto (cuánto texto tiene presente el modelo),
- si debe entender imágenes.
-
-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`.
-
-> **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.
-
-**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).
-
-## ¿Qué modelo elijo?
-
-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 |
-| --- | --- | --- |
-| **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 |
-
- **[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, UD-Q5_K_XL, UD-Q6_K_XL y Q8_0](docs/MODELS.md#unsloths-files-ud-iq4_xs-to-q8_0):** de 4 a 8 bits, más cerca del modelo completo
-  (93-95 % el mismo token siguiente que Q8_0). Rápidos cuando todos los expertos caben en la RAM (~88 GB para
-  UD-Q4_K_XL hasta ~136 GB para Q8_0); con menos RAM, Strata lee una parte desde el SSD mientras responde, lo que es
-  mucho más lento (7-8.5 tokens/s para UD-Q4_K_XL 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.
-
-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`).

- **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.
-
-Más: [dónde se guardan tus chats](docs/INSTALL.md#where-things-are-stored), [la API](docs/DETAILS.md#using-it).
-
-### Opcional: más velocidad con una sola tarjeta cuando todo el modelo cabe en la RAM
-
-Dos ajustes opcionales (de RubenTorney, #1904 y #1905). Ayudan si usas una tarjeta gráfica y tu RAM guarda todos los expertos (el modo arena de Strata, por ejemplo Q2_0 o IQ3_XXS en un PC con 64 GB). Abre tu configuración `strata-<model>.json` en la carpeta de datos de Strata ([dónde](docs/INSTALL.md#where-things-are-stored)) y añade:
-
- **Generación más rápida:** `"--adapt-async", "1"` en la lista `"args"`. La caché de expertos se actualiza entonces en un hilo auxiliar en vez de pausar la respuesta. Medido en una RTX 5070 (Windows, Q2_0): +4-5 % de generación, +7-10 % en código y documentos largos. Las respuestas pueden diferir un poco de las por defecto (son iguales de una ejecución a otra).
- **Lectura del prompt más rápida en Windows:** `"STRATA_PIN_BY_NEED": "1"` en el bloque `"env"`. Windows solo puede bloquear cerca de la mitad de la RAM para la tarjeta; esto bloquea primero los expertos que la tarjeta necesita de verdad. Medido en la RTX 5070: +4,4 % en la lectura del prompt.
-
-```json
-"args": [ ..., "--adapt-async", "1" ],
-"env": { "STRATA_PIN_BY_NEED": "1" }
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
 ```

-Reinicia Strata (`START-HERE.bat` o `./setup.sh`) después del cambio. Para deshacerlo, quita las dos entradas.
+En Windows, abre una terminal nueva después. Luego:

-## ¿Algo salió mal?
+```sh
+strata launch
+```

- **Mi PC se congeló la primera vez que arrancó Strata.** Es normal mientras carga el modelo. Espera y no cierres la
-  ventana. ¿Sigue congelado después de 10 minutos? Reinicia el PC, cierra otros programas y vuelve a intentarlo, o
-  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.

-## Quelle est sa vitesse ?
+**Gratuit, open source, et à vous de l'exécuter.** Utilisez Strata sur votre bureau ou avec vos outils de programmation préférés. Aucun compte nécessaire.

-Nous l'avons mesurée sur deux PC de jeu ordinaires. Un token correspond à environ ¾ d'un mot.
+## Modèles

- **Écrit les réponses :** la vitesse à laquelle la réponse s'affiche dans une courte discussion. 60 tokens par seconde, c'est plus rapide que votre lecture.
- **Lit votre prompt :** la vitesse à laquelle il absorbe ce que vous envoyez (ici un document, du code ou un historique de discussion de 32K tokens).
+Nous recommandons **d'abord ISTA-DASLab**, puis **Unsloth** et d'autres fournisseurs, lorsqu'un modèle compatible tient en mémoire.

-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).
+**Windows PowerShell**

-### Ou faites-le vous-même
-
-[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, M1 à M5, macOS 15 ou plus récent) :** installez une fois les Command Line Tools d'Apple (`xcode-select --install` dans le Terminal ; Xcode lui-même n'est pas nécessaire). Ouvrez ensuite le Terminal dans le dossier Strata et lancez **`./setup.sh`**. Il 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` démarre tout de suite. Quelle taille convient à votre Mac et sa vitesse : [docs/MAC.md](docs/MAC.md).
-
-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 :
-
- quel modèle et quelle taille,
- combien de contexte (la quantité de texte que le modèle garde en tête),
- s'il doit lire les images.
-
-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`.
-
-> **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.
-
-**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).
-
-## Quel modèle choisir ?
-
-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 |
-| --- | --- | --- |
-| **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 |
-
- **[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.

-  complet (93-95 % le même token suivant que Q8_0). Rapides quand tous les experts tiennent dans la RAM (~88 Go pour
-  UD-Q4_K_XL jusqu'à ~136 Go pour Q8_0) ; avec moins de RAM, Strata en lit une partie depuis le SSD pendant qu'il
-  répond, ce qui est bien plus lent (7-8.5 tokens/s pour UD-Q4_K_XL sur un PC avec 64 Go).

-## 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 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.
-
-Plus d'infos : [où sont stockées vos discussions](docs/INSTALL.md#where-things-are-stored), [l'API](docs/DETAILS.md#using-it).
-
-### Optionnel : plus de vitesse sur une seule carte quand tout le modèle tient en RAM
-
-Deux réglages optionnels (de RubenTorney, #1904 et #1905). Ils aident si vous utilisez une seule carte graphique et que votre RAM contient tous les experts (le mode arena de Strata, par exemple Q2_0 ou IQ3_XXS sur un PC de 64 Go). Ouvrez votre configuration `strata-<model>.json` dans le dossier de données de Strata ([où](docs/INSTALL.md#where-things-are-stored)) et ajoutez :
-
- **Génération plus rapide :** `"--adapt-async", "1"` dans la liste `"args"`. Le cache d'experts est alors mis à jour dans un thread auxiliaire au lieu de mettre la réponse en pause. Mesuré sur une RTX 5070 (Windows, Q2_0) : +4-5 % de génération, +7-10 % sur le code et les longs documents. Les réponses peuvent légèrement différer de celles par défaut (elles restent identiques d'une exécution à l'autre).
- **Lecture du prompt plus rapide sous Windows :** `"STRATA_PIN_BY_NEED": "1"` dans le bloc `"env"`. Windows ne peut verrouiller qu'environ la moitié de la RAM pour la carte ; ce réglage verrouille d'abord les experts dont la carte a vraiment besoin. Mesuré sur la RTX 5070 : +4,4 % en lecture du prompt.
-
-```json

-"env": { "STRATA_PIN_BY_NEED": "1" }
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
 ```

-Redémarrez Strata (`START-HERE.bat` ou `./setup.sh`) après la modification. Pour annuler, retirez les deux entrées.
+Sous Windows, ouvrez ensuite un nouveau terminal. Puis :

-## Un problème ?
+```sh
+strata launch
+```

- **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 を使うと、**[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)** を一般的な PC で動かせます。
-通常はサーバーを必要とする大規模で高性能な AI モデルで、チャットやコードの生成、画像の読み取りができます。
-アプリやコーディングエージェントとも連携でき、データは PC の外に送信されません。

-## どのくらい速い？
+**無料でオープンソース。自分の環境で動かせます。** デスクトップで、またはお好みのコーディングツールと一緒に Strata を使えます。アカウントは不要です。

-一般的なゲーミング PC 2 台で速度を測定しました。英語の場合、1 トークンはおよそ ¾ 語に相当します。
+## モデル

- **生成速度：** 短いチャットで回答を生成する速度です。毎秒 60 トークンなら、人が読むよりも速く文章が表示されます。
- **プロンプトの読み込み：** 入力した内容を読み込む速度です。ここでは、文書やコード、チャット履歴など 32K トークン分を読み込ませています。
+まず **ISTA-DASLab** をおすすめします。次に **Unsloth** などの提供元です。メモリに収まる互換モデルがある場合に選べます。

-
-**Mac（Apple シリコン、M1〜M5、macOS 15 以降）：** まず一度だけ Apple の Command Line Tools をインストールします（ターミナルで `xcode-select --install`。Xcode 本体は不要です）。次に Strata フォルダー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）、同じ質問をしてからモデルをダウンロードして起動します。次回からは `./setup.sh` ですぐに起動します。どのサイズが Mac に合うかと速度：[docs/MAC.md](docs/MAC.md)。
-
-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。
-
- 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
-
-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。
-
-> **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。
-
-**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。
-
-## どのモデルを選べばいい
-
-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 |
-| --- | --- | --- |
-| **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 |
-
- **[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 / UD-Q5_K_XL / UD-Q6_K_XL / Q8_0](docs/MODELS.md#unsloths-files-ud-iq4_xs-to-q8_0)：** 4〜8 ビットで、フルモデルにより近いモデルです
-  （次のトークンが Q8_0 と一致する割合は 93〜95%）。すべてのエキスパートが RAM に収まる場合（UD-Q4_K_XL で約 88 GB、
-  Q8_0 で約 136 GB）は高速です。RAM が足りない場合は回答の生成中に一部を SSD から読み込むため、大幅に遅くなります
-  （RAM が 64 GB の PC で UD-Q4_K_XL は毎秒 7-8.5 トークン程度）。
- **[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。
-
-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。

-## 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>
-
- **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。
-
-[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。
-
-### オプション：モデル全体が RAM に収まる場合、GPU 1 枚でさらに高速化
-
-2 つのオプトイン設定です（RubenTorney 氏による #1904 と #1905）。GPU を 1 枚使い、RAM にすべてのエキスパートが収まる場合（Strata の arena モード。例：64 GB の PC で Q2_0 や IQ3_XXS）に効果があります。Strata のデータフォルダーにある設定ファイル `strata-<model>.json`（[場所](docs/INSTALL.md#where-things-are-stored)）を開き、次を追加します：
-
- **生成の高速化：** `"args"` リストに `"--adapt-async", "1"`。エキスパートキャッシュの更新が回答を止めずに補助スレッドで行われます。RTX 5070（Windows、Q2_0）での実測：生成 +4〜5%、コードや長文では +7〜10%。回答はデフォルトとわずかに異なる場合があります（実行ごとには同じです）。
- **Windows でのプロンプト読み込みの高速化：** `"env"` ブロックに `"STRATA_PIN_BY_NEED": "1"`。Windows はGPU 用に RAM の約半分しか固定できないため、この設定で GPU が本当に必要とするエキスパートから先に固定します。RTX 5070 での実測：プロンプト読み込み +4.4%。
-
-```json
-"args": [ ..., "--adapt-async", "1" ],
-"env": { "STRATA_PIN_BY_NEED": "1" }
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
 ```

-変更後は Strata を再起動してください（`START-HERE.bat` または `./setup.sh`）。元に戻すには、2 つの項目を削除します。
+Windows では、インストール後に新しいターミナルを開きます。そのあと:

-## うまくいかないとき
+```sh
+strata launch
+```

- **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。
+画面の案内に従って、モデルをダウンロードして起動します。[ターミナルガイド](docs/TERMINAL_LAUNCH.md)。

-その他の問題と対処方法は、[docs/TROUBLESHOOTING.md](docs/TROUBLESHOOTING.md)をご覧ください。解決しない場合は
-[Issue](https://github.com/Niko1221/Strata/issues) を作成し、Strata フォルダー内の `strata-<model>.log` を添付してください。

-Strata runs **[Qwen3.8-Flash-Next](https://huggingface.co/Qwen/Qwen3.8-Flash-Next)** on a normal PC. This is a
-large, smart AI model that usually needs a server. It chats, writes code, reads pictures and works with your apps
-and coding agents. Nothing leaves your PC.

-## How fast is it?
+**Free, open source, and yours to run.** Use Strata on your desktop or with your favorite coding tools. No account needed.

-We measured it on two ordinary gaming PCs. A token is about ¾ of a word.
+## Models

- **Writes answers:** how fast the reply appears in a short chat. 60 tokens per second is faster than you can read.
- **Reads your prompt:** how fast it takes in what you send (here a 32K-token document, code or chat history).
+We recommend **ISTA-DASLab first**, then **Unsloth** and other providers, where a compatible model fits.

+
+### Terminal app
+
+Prefer the terminal? Install Strata, then run **`strata launch`**.
+
+<details open>
+<summary><b>Install commands</b></summary>
+
+**Linux / Mac**
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh -o install.sh && sh install.sh
 ```

-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).
+**Windows PowerShell**

-### Or do it yourself
-
-[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, M1 to M5, macOS 15 or newer):** install Apple's Command Line Tools once
-(`xcode-select --install` in Terminal; Xcode itself is not needed). Then 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 and how fast it is:
-[docs/MAC.md](docs/MAC.md).
-
-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:
-
- which model and which size,
- how much context (how much text the model keeps in mind),
- whether it should read pictures.
-
-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`.
-
-> **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.
-
-**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).
-
-**Is it fast on your PC?** Run `BENCH.bat` (`./bench.sh`): about 5-10 minutes, it measures chat, 4K/16K prompts and an agent-style session with your own settings and writes a report to share ([how](docs/COMMUNITY_BENCHMARKS.md#run-the-benchmark)).
-
-## Which model should I pick?
-
-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.
-
-| Your RAM | Take | Why |
-| --- | --- | --- |
-| **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 |
-
- **[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, UD-Q5_K_XL, UD-Q6_K_XL and Q8_0](docs/MODELS.md#unsloths-files-ud-iq4_xs-to-q8_0):**
-  4- to 8-bit, closer to the full model (93-95% the same next token as Q8_0). Fast where every expert fits in RAM
-  (~88 GB for UD-Q4_K_XL up to ~136 GB for Q8_0); with less RAM Strata reads part of them from the SSD while it
-  answers, which is much slower (7-8.5 tokens/s for UD-Q4_K_XL 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.
-
-Sizes, downloads and what fits where: [docs/MODELS.md](docs/MODELS.md). To add another model later, run
-`SETUP.bat` (Linux: `./setup.sh --setup`).
-
-## 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 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.
-
-More: [where your chats are stored](docs/INSTALL.md#where-things-are-stored), [the API](docs/DETAILS.md#using-it).
-
-### Optional: more speed on one card when the whole model fits in RAM
-
-Two opt-in settings (by RubenTorney, #1904 and #1905). They help when you run one graphics card and your RAM holds
-every expert (Strata's arena mode, for example Q2_0 or IQ3_XXS on a 64 GB PC). Open your config,
-`strata-<model>.json` in the Strata data folder ([where](docs/INSTALL.md#where-things-are-stored)), and add:
-
- **Faster decode:** `"--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 (they stay the same from run to run).
- **Faster prompt reading on Windows:** `"STRATA_PIN_BY_NEED": "1"` in the `"env"` block. Windows can lock only about
-  half the RAM for the graphics card; this locks the experts the card actually needs first. Measured on the RTX 5070:
-  +4.4% prompt reading.
-
-```json
-"args": [ ..., "--adapt-async", "1" ],
-"env": { "STRATA_PIN_BY_NEED": "1" }
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
 ```

-Restart Strata (`START-HERE.bat` or `./setup.sh`) after the change. To undo, remove the two entries.
+On Windows, open a new terminal afterwards. Then:

-## Something went wrong?
+```sh
+strata launch
+```

- **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.
+Follow the prompts to download and start a model. [Terminal guide](docs/TERMINAL_LAUNCH.md).

-More problems and their fixes: [docs/TROUBLESHOOTING.md](docs/TROUBLESHOOTING.md). Still stuck? Open an
-[issue](https://github.com/Niko1221/Strata/issues) and attach `strata-<model>.log` from the Strata folder. Found a

+  <br><sub>Watch your model and hardware while it runs.</sub>

-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.

+[Build from source](docs/SOURCE_INSTALL.md) · [Docker](docs/DOCKER.md) · [Full install guide](docs/INSTALL.md)

- **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.

-<p align="center"><img src="docs/media/guess-and-check.svg" width="860" alt="A small helper guesses the next words; the big model checks them all at once and keeps the right ones"></p>
+## Hardware

- **Guess, then check:** a small helper guesses the next few words. The big model checks them all at once. 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.

-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.

-## Qual é a velocidade?
+**Gratuito, de código aberto e seu para executar.** Use o Strata no desktop ou com suas ferramentas de programação favoritas. Não precisa de conta.

-Medimos em dois PCs gamer comuns. Um token equivale a cerca de ¾ de uma palavra.
+## Modelos

- **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).
+Recomendamos **primeiro a ISTA-DASLab**, depois a **Unsloth** e outros provedores, quando um modelo compatível cabe na memória.

+**Linux / Mac**
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh -o install.sh && sh install.sh
 ```

-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.
+**Windows PowerShell**

-### Ou faça você mesmo
-
-[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.
-
-**Mac (Apple Silicon, M1 a M5, macOS 15 ou mais recente):** instale uma vez as Command Line Tools da Apple (`xcode-select --install` no Terminal; o Xcode em si não é necessário). Depois abra o Terminal na pasta do Strata e rode **`./setup.sh`**. Ele compila o motor do Mac no seu Mac (uns 7 minutos), faz as mesmas perguntas, baixa o modelo e o inicia. Da próxima vez, `./setup.sh` inicia na hora. Qual tamanho cabe no seu Mac e qual a velocidade: [docs/MAC.md](docs/MAC.md).
-
-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.
-Os tamanhos menores são mais rápidos. Os maiores são um pouco mais inteligentes.
-
-| Sua RAM | Escolha | Por quê |
-| --- | --- | --- |
-| **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 |
-
- **[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, UD-Q5_K_XL, UD-Q6_K_XL e Q8_0](docs/MODELS.md#unsloths-files-ud-iq4_xs-to-q8_0):** de 4 a 8 bits, mais próximos do modelo
-  completo (93-95% o mesmo próximo token que o Q8_0). Rápidos quando todos os especialistas cabem na RAM (~88 GB para
-  o UD-Q4_K_XL até ~136 GB para o Q8_0); com menos RAM, o Strata lê uma parte do SSD enquanto responde, o que é bem
-  mais lento (7-8.5 tokens/s para o UD-Q4_K_XL 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.
-
-Tamanhos, downloads e o que cabe onde: [docs/MODELS.md](docs/MODELS.md). Para adicionar outro modelo depois, rode
-`SETUP.bat` (Linux: `./setup.sh --setup`).
-
-## 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 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.
-
-Mais: [onde suas conversas ficam salvas](docs/INSTALL.md#where-things-are-stored), [a API](docs/DETAILS.md#using-it).
-
-### Opcional: mais velocidade com uma placa quando o modelo inteiro cabe na RAM
-
-Duas configurações opcionais (de RubenTorney, #1904 e #1905). Elas ajudam quando você usa uma placa de vídeo e sua RAM guarda todos os experts (o modo arena do Strata, por exemplo Q2_0 ou IQ3_XXS num PC com 64 GB). Abra sua configuração `strata-<model>.json` na pasta de dados do Strata ([onde](docs/INSTALL.md#where-things-are-stored)) e adicione:
-
- **Geração mais rápida:** `"--adapt-async", "1"` na 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): +4-5% de geração, +7-10% em código e documentos longos. As respostas podem diferir um pouco do padrão (ficam iguais de uma execução para outra).
- **Leitura do prompt mais rápida no Windows:** `"STRATA_PIN_BY_NEED": "1"` no bloco `"env"`. O Windows só consegue travar cerca de metade da RAM para a placa; isto trava primeiro os experts de que a placa realmente precisa. Medido na RTX 5070: +4,4% na leitura do prompt.
-
-```json
-"args": [ ..., "--adapt-async", "1" ],
-"env": { "STRATA_PIN_BY_NEED": "1" }
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
 ```

-Reinicie o Strata (`START-HERE.bat` ou `./setup.sh`) depois da mudança. Para desfazer, remova as duas entradas.
+No Windows, abra um novo terminal depois. Em seguida:

-## Algo deu errado?
+```sh
+strata launch
+```

- **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.
+Siga as instruções para baixar e iniciar um modelo. [Guia do Terminal](docs/TERMINAL_LAUNCH.md).

-Mais problemas e como resolver: [docs/TROUBLESHOOTING.md](docs/TROUBLESHOOTING.md). Ainda sem solução? Abra uma
-[issue](https://github.com/Niko1221/Strata/issues) e anexe o `strata-<model>.log` da pasta do Strata. Encontrou um

+
+**Linux / Mac**
+
+```sh
+curl -fsSL https://github.com/Niko1221/Strata/releases/latest/download/install.sh -o install.sh && sh install.sh
 ```

-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。
+**Windows PowerShell**

-### 或者自己动手
-
-[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`**。
-
-**Mac（Apple 芯片，M1 到 M5，macOS 15 或更新版本）：** 先安装一次 Apple 的 Command Line Tools（在终端里运行 `xcode-select --install`；不需要 Xcode 本身）。然后在 Strata 文件夹里打开终端，运行 **`./setup.sh`**。它会在你的 Mac 上编译 Mac 版引擎（大约 7 分钟），问同样的问题，下载模型并启动。下次运行 `./setup.sh` 会马上启动。哪个大小适合你的 Mac、速度如何：[docs/MAC.md](docs/MAC.md)。
-
-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：
-
- 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。
-
-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`。
-
-> **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。
-
-**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)。
-
-## 该选哪个模型
-
-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 |
-| --- | --- | --- |
-| **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 |
-
- **[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、UD-Q5_K_XL、UD-Q6_K_XL 和 Q8_0](docs/MODELS.md#unsloths-files-ud-iq4_xs-to-q8_0)：** 4 到 8 位，更接近完整模型（下一个 token
-  与 Q8_0 相同的比例为 93-95%）。所有专家都能放进内存时速度很快（UD-Q4_K_XL 约需 88 GB，Q8_0 约需 136 GB）；内存不够时，
-  Strata 回答时要从 SSD 读取一部分，会慢很多（64 GB 的电脑上 UD-Q4_K_XL 每秒 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。
-
-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`）。
-
-## 使用方法
-
-<p align="center"><img src="docs/media/runpagoda.png" width="900" alt="Strata 应用的 Monitor 标签页，旁边是一个编程智能体"><br>
-<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。
-
-更多：[聊天记录存在哪里](docs/INSTALL.md#where-things-are-stored)、[API](docs/DETAILS.md#using-it)。
-
-### 可选：整个模型都能放进内存时，单卡再提速
-
-两个可选设置（来自 RubenTorney 的 #1904 和 #1905）。适用于只用一张显卡、并且内存能放下所有专家的情况（Strata 的 arena 模式，例如 64 GB 电脑上的 Q2_0 或 IQ3_XXS）。打开 Strata 数据文件夹里的配置文件 `strata-<model>.json`（[在哪里](docs/INSTALL.md#where-things-are-stored)），加入：
-
- **生成更快：** 在 `"args"` 列表里加 `"--adapt-async", "1"`。专家缓存改在辅助线程里更新，不再暂停回答。在 RTX 5070（Windows，Q2_0）上实测：生成 +4-5%，代码和长文档 +7-10%。回答可能与默认设置略有不同（但每次运行都一样）。
- **Windows 上读取提示更快：** 在 `"env"` 块里加 `"STRATA_PIN_BY_NEED": "1"`。Windows 只能为显卡锁定大约一半的内存；这个设置会先锁定显卡真正需要的专家。在 RTX 5070 上实测：读取提示 +4.4%。
-
-```json
-"args": [ ..., "--adapt-async", "1" ],
-"env": { "STRATA_PIN_BY_NEED": "1" }
+```powershell
+irm https://github.com/Niko1221/Strata/releases/latest/download/install.ps1 | iex
 ```

-修改后重启 Strata（`START-HERE.bat` 或 `./setup.sh`）。要撤销，删掉这两项即可。
+在 Windows 上，安装后请打开一个新的终端。然后运行：

-## 出问题了？
+```sh

+
+## 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 -o install.sh && sh install.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).

+"""The installed Windows app, closed every way, with a stub engine: nothing may be left running.
+
+    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.

+ * STRATA_NO_ACQUIRE=1; Control found beside the host), against a scratch component folder holding a fake engine
+ * package and a scratch install folder holding one run config. Everything per-user (profiles, runtime state, host data,
+ * components) lives under --work, so the real profile of whoever runs this is never read or written.
+ *
+ * Steps (each one printed, the run exits 1 if any fails):
+ *   host health, Control status (engine usable, acquiring forbidden), models from Control, load through the host
+ *   (profile + `runtime start` under the owner runtime), a chat answer from the stub engine, a second client attaches to
+ *   the same owner/instance, unload stops it, no engine for this PC is a notice with nothing started, the Tauri-style
+ *   clean shutdown stops the engines the host started, a hard-killed host takes its engine with it.
+ * With --spy the host runs under tests/helpers/acquire-spy.mjs and the run fails on any attempt to reach the internet or
+ * run an installer.
