LM Studio
Download and run open-source LLMs on your own machine with a clean desktop UI and a local OpenAI-compatible API. No terminal required.
Overview
LM Studio is a desktop application for discovering, downloading, and running open-source LLMs locally on your own machine — with a clean chat UI and a local server that mimics the OpenAI API. Where Ollama requires the terminal, LM Studio gives you a graphical interface: browse a model catalog, download with one click, and run locally with no cloud dependency. It exposes a local OpenAI-compatible API so any app that works with ChatGPT can be pointed at your local model instead. Used by developers who want privacy (nothing leaves their machine), researchers testing different model families, and teams that need to work offline. Supports GPU acceleration on Mac, Windows, and Linux.
