LM Studio is a desktop app for downloading open language models and running them on your own computer, with a chat window and a local API.
In plain words
You pick a model in the app's Discover tab, download its weight files, and chat with it. Once a model is downloaded, chatting, asking questions about your documents and running a local server all work without the internet, and your documents stay on your machine. The local server copies OpenAI's API style, so other programs can use the model as if it were a cloud service.
A quick example
Imagine a writer who wants an AI helper that never sends drafts online. They download a small open model in LM Studio, turn off Wi-Fi, and ask it to suggest titles, all on their laptop.
Where you'll meet it
- Trying open models privately on a laptop or desktop.
- Testing apps against a local, OpenAI-style server.
