About the Vercel AI SDK

The Vercel AI SDK is an open-source TypeScript toolkit designed to simplify the integration of large language models (LLMs) and AI capabilities into web applications. It provides a unified API to interact with various AI model providers (e.g., OpenAI, Anthropic, Google, Mistral, xAI, Amazon Bedrock) and offers framework-agnostic hooks for building conversational, streaming, and generative user interfaces. Key features include streaming-first UI helpers (like useChat and useCompletion), support for text generation, structured data generation (JSON), and tool calling (for interacting with external systems). The SDK is optimized for modern web frameworks like Next.js, React, Svelte, Vue, and runtimes like Node.js, enabling developers to build rich, interactive AI experiences with less boilerplate code.
