LM Studio for Mac: Run AI Models Offline, Privately and for Free
AI chat assistants are useful, but the best ones cost a monthly subscription, and everything you type goes to someone else's servers.
LM Studio runs AI models on your own Mac instead. Download a model once, and chat with it offline, privately and for free. Apple Silicon Macs are surprisingly good at it.
What is LM Studio?
LM Studio is a free desktop app for discovering, downloading and running open AI language models on your own computer. On Macs it requires Apple Silicon (M1 or later) and uses Apple's MLX framework for speed. It has a chat interface, lets you chat with your own documents, and can run a local server for other apps. It's free for home and work use, but not open source.
