What is Vercel AI SDK?

Vercel AI SDK is a TypeScript toolkit designed for developers building web applications with AI features. It provides libraries and utilities to integrate large language models, handle streaming responses, and manage AI interactions within your application. The SDK works across multiple AI providers, allowing you to switch between different models without rewriting core logic. It's particularly useful if you're building with Next.js or other modern JavaScript frameworks, though it works in any TypeScript environment. Since it's open source, you can inspect the code, contribute improvements, and use it without licensing costs.
