100% Private

No data ever leaves your machine. No telemetry, no analytics, no phone-home. Fully air-gapped capable.

Plugin System

Extend with WASM plugins. Add tools, custom models, RAG pipelines, and middleware — all hot-reloadable.

OpenAI-Compatible API

Drop-in replacement for OpenAI and Claude APIs. Your existing code works without changes.

Streaming First

Server-Sent Events streaming out of the box. Real-time token generation with sub-millisecond overhead.
