Search and download open-weight models like Llama, Mistral, and Qwen from inside the app.

🖥️

Local API server

Spin up an OpenAI-compatible endpoint on your machine for your own scripts and tools.

🔒

Private by design

No account, no telemetry required — your prompts and documents never leave your device.

Good to know: This is an independent overview, not affiliated with LM Studio. The button above links out to the developer's own site — this page never stores or serves the installer itself, which is the safest way to get it.
