LM Studio is a desktop application for discovering, downloading, running, and serving language models locally, with chat, document use, developer APIs, and optional hosted model inference.
Users download only from the official site, verify model licenses and memory requirements, test on non-sensitive data, bind local servers safely, add authentication or network isolation, monitor resource use, and review outputs and tool calls.
The desktop application is free for home and work use. Local models use the user’s hardware; optional LM Studio Cloud models are billed by token and vary by model.
Local models can still hallucinate, contain malicious or incompatible weights, expose an open local server, or consume substantial memory and power. Model provenance, licenses, network security, updates, resource limits, and human review matter.
