## What it is
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
