LM Studio is a local AI runtime built by Element Labs, Inc., enabling developers to run and serve LLMs entirely on-device across Windows, macOS, and Linux. It exposes an OpenAI-compatible REST API, making it a drop-in replacement for cloud LLM endpoints in existing applications. The platform ships official lmstudio-js (npm) and lmstudio-python (pip) SDKs, supports Apple MLX models for Apple Silicon hardware acceleration, and includes lms, a CLI tool for scripting and automation. For server and CI/CD environments, the headless llmster binary strips the GUI and can be installed on Linux boxes or cloud instances with a single curl/PowerShell command.
