LMStudio SDKs

Programmatic access to local Large Language Models (LLMs) via dedicated Python and TypeScript SDKs, featuring OpenAI-compatible APIs and agentic tool-calling.

The LM Studio SDKs provide developers with robust libraries—`lmstudio-python` and `lmstudio-js`—to integrate local LLMs directly into their applications. These SDKs simplify local AI development, offering core functionality like chat completions, text generation, and embeddings through an OpenAI-compatible interface. A key differentiator is the `.act()` API, which enables advanced agent-oriented programming: models autonomously utilize tools and execute multi-step workflows. Developers gain precise control over resource management, including the ability to load and unload models (e.g., Qwen3, Gemma3) as needed, ensuring efficient use of local hardware without complex configuration.
