Building AI-Powered Features with the Vercel AI SDK
Add streaming chat, text completion, and structured data extraction to your Next.js app using the Vercel AI SDK and OpenAI.
The AI SDK Advantage
The Vercel AI SDK provides a unified interface for working with AI models. It handles streaming, structured output, and tool calling — so you can focus on building features, not infrastructure.
Streaming Chat in 20 Lines
Using the useChat hook from ai/react you can build a streaming chat interface in just 20 lines of code.
Structured Data Extraction
Extract typed data from unstructured text using generateObject and Zod schemas.
Tip
Use Zod schemas to get type-safe AI outputs. The SDK validates the response automatically.
Tool Calling
Let the AI invoke your functions with type-safe tool definitions.
Production Considerations
- Rate limiting — protect your API routes
- Streaming — always stream for better UX
- Caching — cache deterministic results
- Cost monitoring — track token usage per user

The structured output with Zod schemas is brilliant. We just used this pattern for our customer support chatbot and the type safety is amazing.
