The AI SDK is a TypeScript toolkit from Vercel for building AI-powered applications and agents, providing a unified API for text generation, structured data, tool calling, and streaming across 100+ models from multiple providers. It includes framework-agnostic UI hooks for building chat and generative interfaces with React, Next.js, Vue, Svelte, and Node.js.

Use cases

  • build a chatbot with streaming responses in nextjs
  • call openai anthropic and gemini models through one unified api
  • build ai agents with tool calling in typescript
  • generate structured data from llm responses
  • add a chat interface to a react or vue app
  • switch llm providers with one line of code
  • integrate model context protocol mcp tools
  • build generative ui components powered by llms

When to choose

  • you are building ai features in a typescript or javascript app
  • you want provider-agnostic llm integration with streaming and fallbacks
  • you need chat or generative ui hooks for react, next.js, vue, or svelte
  • you are building agents with tool calling and workflow patterns

When to avoid

  • you work primarily in python and want a mature sdk (the python version is still in beta)
  • you need direct low-level control over a single provider's api
  • you are building a non-javascript application
