One binary
A single Rust binary: the agent loop, the model runtimes, and the memory system — all in one file.
Download
Get the engine. It's one line.
The installer downloads the prebuilt openeng binary, verifies its SHA-256 checksum, and puts it on your PATH. A default open-weight model is pulled on first run; each config then downloads whatever models it references from its registry — Hugging Face, the Ollama library, ModelScope, or a direct URL.
Linux x86_64 (and WSL) — live today
curl -fsSL https://openeng.ai/engine/install.sh | bashOpen-weight models
Downloads open-weight models from any registry and runs them isolated in a sandbox on your machine. After the download, inference is offline.
Verified
TLS download, published SHA-256, and a script that refuses anything that doesn't match.

After the install
Sign in once, then it's local
- 1Run openeng. Choose “Login through browser” — with a device-code fallback for headless machines — or sign in with an API key.
- 2If the model download was skipped or interrupted, the engine finishes it on first launch.
- 3Your Console-published config resolves automatically — agents, models, cells, MCP servers.
- 4Type a prompt, or /help for the command reference. Free covers the full on-device agent.
