AI SDK from Vercel

The Vercel AI SDK is a comprehensive open-source library designed to simplify adding AI features—like chatbots, text generation, and real-time assistant experiences—to modern web applications. Supporting popular frameworks such as Next.js, React, Vue, and Svelte, it offers standardized components for both server and client: developers can easily stream text or structured results, switch between providers like OpenAI, Anthropic, and Google Gemini, and leverage hooks for state management and UI updates. By abstracting away the complexity of managing multiple AI APIs, handling streaming responses, and coordinating authentication, the SDK makes it possible to rapidly prototype, test, and deploy multi-model AI solutions that scale seamlessly with Vercel’s edge infrastructure.

Key features include instant provider swaps, multimodal support, structured data generation, direct integration with front-end UI, and compatibility with custom agent frameworks like VoltAgent. This unified approach helps teams deliver engaging GenAI interactions, personalized knowledge assistants, and advanced automation, all with production-ready stability and minimal setup.
