Parallel Requests Requests to the same model can now be processed in parallel, instead of being queued. This unlocks high throughput use cases via the API, or parallel requests in the chat interface with Split View.

New REST API: /v1/chat Allows you to run your local models and give them local MCPs to use. Additionally, you can now generate permission tokens to control which clients can interact with your server.

0.4.0 の大型アップデート最高です！ 0.4.1 の日本語入力まわり（lms chat の non-ASCII 修正）も手元で検証して、複数モデルで全部パスしました。 「入力が本当にモデルに届いているか」をログで確認できるの、安心感が段違いです。ありがとうございます！

Congrats! I recently started using lm studio it’s amazing, but one thing I noticed is I can’t pin a model settings or plugin settings to a model, and have to configure every time I load a model or start a new chat. Hopefully that’s improved
