The flash model is `deepseek-flash` everywhere: the id it is served under lost the generation it never needed. An installed entry is renamed rather than left behind, and the rename moves every key that named the old id with it — a price or an effort list stranded under the old key stops answering for the model that replaced it, which reads downstream as a setting the user edited reverting to its default. A preset is now what settles which of its models read images. Reading a name misses every Kimi, Qwen, MiniMax and Claude model these presets declare, and `deepseek-flash` spells nothing at all; the spelling stays the last resort for an address nothing has declared, and stays a correctable suggestion rather than a claim. The connection that existed only to reach an image-taking model folds into the entry beside it once that entry reaches the same model on the same key — unless its user configured it, because folding would answer their edit by deleting where it lived. A preset changing shape reaches installs holding the old one through one declared shape per generation and one upgrade that brings a matching entry forward. The guard is the whole shape, because an entry holding what we shipped is ours to move and anything else its user curated. That retires nine hand-written migrations that each recognised one vendor by hand. Official list prices live once, in `officialRates`, oldest generation first. A price change appends rather than edits: the superseded rate is what lets an installed config be recognised as holding one of ours and brought forward, instead of quoting a retired rate for the rest of its life. `config` reads them through `billing.CurrentRate` and `SupersededRates` and restates none of them — a table written twice is one that drifts, which is how a vendor's USD rate ended up published on one side only. `make pricecheck` reads each vendor's own page and compares it against that table, and says how long ago a person last confirmed each one. It reaches the network, so it stays out of lint and out of CI. A page it cannot read exits non-zero: unread is its own verdict and never counts as agreement.

Open source · MIT · a single Go binary
A coding agent you can leave running.
One local engine, four ways in — terminal, desktop app, browser, or your editor over ACP. Plan mode, permissions, a workspace sandbox and per-turn checkpoints keep a long autonomous run something you can still read and undo.

Features
- Config-driven. Providers, the agent, enabled tools, and plugins are all
declared in
reasonix.toml. No hardcoded models. - Multi-model & composable. DeepSeek ships as a preset; any OpenAI-compatible endpoint is a config entry, not new code. Optionally run two models together (executor + planner) in separate, cache-stable sessions.
- Plugin-driven. MCP servers contribute tools, prompts, and resources; Extension Protocol v1 sidecars can also intercept runtime events, contribute Providers and structured UI, and ship versioned plugin packages.
- Cache-aware context maintenance. Startup injects a small stable environment summary, stale tool output is snipped/pruned before summary compaction, and the built-in tool schema contract is documented for regression review.
- Zero-friction distribution.
CGO_ENABLED=0single binary; cross-compile to six targets with one command. The result is a fully self-contained static binary — nothing to install on the target machine beyond the binary itself.
Install
Choose the path that matches how you want to use Reasonix. The CLI/TUI, desktop app, and VS Code extension all use the same local Reasonix engine.
Path A: CLI / TUI
Install the native binary through npm on any supported platform, or use Homebrew on macOS:
npm i -g reasonix # any OS; pulls the prebuilt native binary
brew install esengine/reasonix/reasonix # macOS
Prebuilt archives (darwin|linux|windows × amd64|arm64) and SHA256SUMS are on
every GitHub release.
Path B: Desktop app
Use the official download page for the latest desktop build.
| Platform | Package | Architecture |
|---|---|---|
| macOS | Universal .dmg or .zip |
Apple Silicon / Intel |
| Windows | Installer .exe or portable .zip |
x64 / ARM64 |
| Linux | .deb or .tar.gz |
x64 |
Windows installers are code-signed through SignPath.io with a free certificate provided by the SignPath Foundation.
Path C: VS Code extension
Complete Path A first. The extension does not bundle the CLI; it starts your
local reasonix acp backend and adds native chat, editor context, tool-call
approvals, model selection, and workspace sessions.
- VS Code: install from Visual Studio Marketplace
- VSCodium / Eclipse Theia: install from Open VSX Registry
- Extension ID:
SivanLiu.reasonix-agent· source and usage guide
Path D: Build from source
Clone the repository first:
git clone https://github.com/esengine/DeepSeek-Reasonix.git
cd DeepSeek-Reasonix
CLI
The CLI build requires Go 1.25+. The module pins a toolchain directive;
keep GOTOOLCHAIN=auto so Go downloads the pinned toolchain, or install it.
make build # -> bin/reasonix(.exe)
make cross # -> dist/ (darwin|linux|windows × amd64|arm64)
Desktop
The desktop build additionally requires:
- Node 24+ and pnpm 10 (
npm install -g pnpm@10) for the frontend - Wails CLI matching the shared
.wails-versionpin
make wails-install
cd desktop
wails build
See the desktop build guide for platform webview dependencies and Linux build tags.
Quick start
CLI / TUI
These commands are for the CLI/TUI installed through Path A:
reasonix setup # configure a provider and model
reasonix # start an interactive session
reasonix run "implement the TODOs in main.go"
In an interactive session, run /init when you want Reasonix to create project
instructions.
Desktop app
Download the installer for your platform from the official download page, install and launch Reasonix, then configure a provider and model in the app. The CLI commands above are not required for the desktop app.
For advanced CLI usage and configuration, see the CLI reference, Guide, and configuration paths.
