About Vercel AI SDK
The Vercel AI SDK is a TypeScript library that makes it straightforward to add AI features to web applications. It offers one consistent interface across many model providers, so switching from one to another takes a line or two.
It handles streaming responses, structured output, tool calling and agents, and includes UI hooks for React, Next.js, Vue and Svelte that make chat interfaces simple to build. It works anywhere JavaScript runs, not only on Vercel.
The SDK is free and open source. It is a favorite of front-end and full-stack developers.
