Overview
What LM Studio is
The desktop app combines a model catalog, local chat interface, runtime controls, and a local server. Developers can point existing OpenAI-compatible clients at the server or use LM Studio's JavaScript, Python, CLI, and headless tools.
Local execution gives users more control over data and recurring API costs, but it shifts model selection, storage, memory, updates, and performance to the user's hardware. LM Studio Bionic is a separate Windows agent app that can use local, remote, or optional cloud models; this page focuses on the core LM Studio application.
