## What it is
TanStack AI is a type-safe, provider-agnostic TypeScript SDK for building AI applications with streaming chat, tool calling, agents, structured outputs, and multimodal features. It offers a framework-free core with bindings for React, Vue, Svelte, Solid, Preact, Angular, and vanilla JS, plus adapters for OpenAI, Anthropic, Gemini, OpenRouter, Ollama, and more.

## Use cases
- add streaming chat to a react app
- build tool-calling agents in typescript
- switch between openai anthropic and gemini without rewriting code
- build a chatbot with human-in-the-loop tool approval
- generate images audio and video from llm apps
- connect mcp servers to a chat interface
- run a coding agent in a sandbox from my app
- extract structured output from llm responses with zod schemas

## When to choose
- you want a type-safe, framework-agnostic AI SDK with no vendor lock-in or hosted gateway
- you need multi-provider support with swappable adapters across many LLM vendors
- you use React, Vue, Svelte, Solid, Preact, or Angular and want native hooks/composables
- you need advanced features like tool approval flows, MCP integration, sandboxes, or realtime voice

## When to avoid
- you want a fully managed, hosted AI platform with minimal setup
- you work outside the TypeScript/JavaScript ecosystem primarily
- you need a stable 1.0 release - the project is still in RC phase
- you only need a simple single-provider OpenAI wrapper with minimal abstraction
