LM Studio

free
4.5 / 5.0

LM Studio is a free desktop application for Windows, Mac, and Linux that lets users discover, download, and run open-source large language models locally through a polished ChatGPT-like graphical interface. It supports quantised GGUF models from Hugging Face, provides an in-app model browser, and runs a local OpenAI-compatible API server so developers can point existing applications to local models. LM Studio makes local AI accessible to non-technical users while also satisfying developers who need local inference infrastructure.

Best for: Non-technical users and developers who want a polished desktop experience for running open-source AI models locally.
