LM Studio as a Local LLM API Server

Run an LLM API server on localhost with LM Studio

You can serve local LLMs from LM Studio's Developer tab, either on localhost or on the network.

LM Studio's APIs can be used through REST API, client libraries like lmstudio-js and lmstudio-python, and compatibility endpoints like OpenAI-compatible and Anthropic-compatible.

Running the server

To run the server, go to the Developer tab in LM Studio, and toggle the "Start server" switch to start the API server.

Alternatively, you can use lms (LM Studio's CLI) to start the server from your terminal:

lms server start
