Osaurus is an open-source local inference runtime for macOS, written in Swift and optimized for Apple Silicon.

It lets you run Apple Foundation Models locally — fully accelerated by the Neural Engine — while also exposing OpenAI- and Ollama-compatible endpoints, so you can connect your favorite apps, tools, or clients without any code changes.

Key points:

* Supports Apple Foundation Models natively

* Compatible with OpenAI & Ollama APIs

* ~7 MB binary, runs locally (no cloud, no telemetry)

* MIT Licensed, open source

We’re exploring what a local-first AI ecosystem could look like — where inference, privacy, and creativity all happen on your own hardware. Feedback and testing welcome!
