What is LM Studio?

LM Studio is a free desktop app for running open-weight models locally with a proper graphical interface: browse and download models from Hugging Face, chat with them, tune settings, and expose a local OpenAI-compatible server. It is the point-and-click counterpart to Ollama.

Key features

Graphical model browser with hardware-compatibility hints
Built-in chat interface with system prompts and presets
Local OpenAI-compatible API server
Chat with your own documents locally (RAG)
Runs on Mac (Apple silicon), Windows and Linux

Pros

No terminal needed — the friendliest way to try local models
Tells you which models will actually fit your machine before you download
Local document chat keeps sensitive files off the cloud

Cons

Closed source, unlike Ollama
Commercial use requires contacting the company
Same hardware limits as any local runner — small models on small machines

Best for
