Vercel AI SDK

The toolkit for building AI-powered web applications

Vercel's AI SDK makes it easy to build streaming AI interfaces in web apps. If your product needs a ChatGPT-like streaming response UI (and it might), this is one of the easiest ways to build it. It handles the annoying parts: token streaming, state management, model switching.

Use Cases

Streaming chat interfaces

That character-by-character typing effect you see in ChatGPT. Users expect this now.

Generative UI

AI responses that include interactive components — not just text, but buttons, forms, charts.

Multi-model applications

Switching between OpenAI, Anthropic, Google, and others without rewriting your code.

AI-powered forms

Structured data extraction from natural language input.

Key Features

  • Works with Next.js, Nuxt, SvelteKit, and more
  • Unified API for OpenAI, Anthropic, Google, Mistral, etc.
  • Built-in streaming support
  • React hooks for chat, completion, and object generation
  • TypeScript-first with full type safety

Why This Matters for PMs

If your product is a web application and you're adding AI features, Vercel AI SDK significantly reduces development time. As a PM, the key thing to understand is that it handles the UX layer of AI — the streaming, the state management, the model abstraction. Your team can ship AI features faster, and you can switch models without a major rewrite if OpenAI gets expensive or Anthropic gets better.
