About LM Studio
LM Studio is a free desktop application for running large language models locally on your own computer. It supports models from the Hugging Face ecosystem, including Llama 3, Mistral, Phi, Gemma, and dozens of other open-weight models, with a simple interface for downloading, managing, and chatting with them. Because everything runs on-device, LM Studio offers complete privacy - your conversations never leave your machine, making it appealing for developers, researchers, and privacy-conscious users. The application includes a built-in chat interface similar to ChatGPT, as well as a local API server that is fully compatible with the OpenAI API format. This means you can point any OpenAI-compatible application or SDK to your local LM Studio server and use local models as a drop-in replacement for cloud APIs. LM Studio requires a Mac, Windows, or Linux machine with sufficient RAM and ideally a GPU for reasonable inference speeds. It is completely free, with no usage limits - the only cost is your own hardware. For developers experimenting with LLMs or building applications that need on-device AI, LM Studio is the most accessible entry point.
