AI SDK

The AI SDK is Vercel's open-source, TypeScript toolkit: it provides a unified API for building AI applications across major web frameworks (React, Vue, Svelte) and over a dozen model providers.

This is the definitive TypeScript toolkit for AI application development, created by Vercel and the Next.js team. It abstracts away the complexity of integrating Large Language Models (LLMs) from providers like OpenAI, Google Generative AI, and Anthropic, allowing you to switch models by changing a single line of code. The SDK includes two main libraries: AI SDK Core for unified API calls (streamText, generateObject) and AI SDK UI for framework-agnostic hooks (useChat) to build rich, generative user interfaces fast. With over 2 million weekly downloads, it’s a proven solution for deploying robust, multi-provider AI apps on the web.
