Vercel AI SDK
frameworkThe Vercel AI SDK is a TypeScript-first toolkit for building AI-powered applications, particularly with React and Next.js. It provides hooks and utilities for streaming LLM responses, managing conversations, handling tool calls, and rendering AI-generated UI.
The SDK supports multiple LLM providers through a unified interface, with first-class support for OpenAI, Anthropic, Google, and others. Its streaming architecture is optimized for web applications, providing real-time response rendering.
For TypeScript developers building web-facing AI applications, the Vercel AI SDK offers the tightest integration with the React/Next.js ecosystem. It handles the complexity of streaming, tool use, and multi-step agent workflows.
