What is AI SDK?

AI SDK is an open-source TypeScript toolkit for building AI-powered applications and agents. It provides a unified API for text generation, structured objects, tool calls, and agent building, with support for 100+ models from multiple providers. The SDK works with React, Next.js, Vue, Svelte, Node.js, and more, and is powered by Vercel.

How to use AI SDK?

  • Install the SDK with 'npm install ai', then import generateText from 'ai' and call it with a model and prompt.
