I spent the weekend vibe-coding in Cursor and ended up with a small Swift app that turns the new macOS 26 on-device Apple Intelligence models into a local server you can hit with standard OpenAI /v1/chat/completions calls. Point any client you like at http://127.0.0.1:11535.

* Works with any OpenAI-compatible client * Nothing leaves your Mac * Open source, MIT-licensed

It was a fun hack—let me know if you try it out or run into any weirdness. Cheers!
