lmstudio-js is the official TypeScript/JavaScript client SDK for LM Studio, enabling use of locally running LLMs for chat, completions, embeddings, and tool-based agents. It also supports loading, configuring, and unloading models from memory in Node and browser environments.

Use cases

• chat with local llms from typescript
• build autonomous agents that run locally
• generate text embeddings locally
• load and unload llm models from memory programmatically
• define tools for llm function calling
• replace openai sdk with local model client

When to choose

• you use LM Studio to run local models and want a typed SDK
• you need model lifecycle management (load/unload, GPU offload, context length)
• you want fully local agents with tool calling
• you develop in TypeScript/JavaScript on Node or browser

When to avoid

• you only call OpenAI or other cloud-hosted APIs
• you need a Python SDK (use lmstudio-python instead)
• you don't run LM Studio or a compatible local server
