AI SDK

The AI SDK is the TypeScript toolkit designed to help developers build AI-powered applications with React, Next.js, Vue, Svelte, Node.js, and more.

Why use the AI SDK?

Integrating large language models (LLMs) into applications is complicated and heavily dependent on the specific model provider you use.

  • AI SDK Core: A unified API for generating text, structured objects, and tool calls with LLMs.
  • AI SDK UI: A set of framework-agnostic hooks for quickly building chat and generative user interface.

Model Providers

The AI SDK supports multiple model providers.
