## Overview

- **Who it's for**: Developers and technically curious users who want to run LLMs on their own hardware instead of calling a cloud API, for privacy, offline use, or cost reasons.
- **What you get**: A desktop app with a model library for discovering and downloading open-weight LLMs (GGUF and Apple MLX formats), a built-in chat UI for interacting with them, and a local inference server that exposes an OpenAI-compatible API. Runs on Windows, Mac, and Linux, with all inference happening on-device.
- **How it works**: You download a model through LM Studio's built-in catalog, then either chat with it directly in the app or start the local server so other apps and scripts can call it over HTTP using the OpenAI API format.
