Vercel AI SDK

Vercel AI SDK is a universal, open-source TypeScript SDK designed for developers building AI-powered applications and agents. It provides a unified API for interacting with multiple AI providers and models—including OpenAI, Anthropic, Google, Meta, Mistral, and more—enabling text, image, video, and speech generation, as well as tool calling, error handling, and streaming. Designed for compatibility with major frameworks like Next.js, React, Vue, Svelte, and Node.js, it supports multi-provider switching, real-time responses, built-in fallbacks, and agent-building capabilities.
