Vercel released AI SDK 5, a major update to its open-source TypeScript/JavaScript AI toolkit. The release introduces fully typed chat integrations for React, Svelte, Vue, and Angular, with separate UI and model message types and customizable data parts for streaming arbitrary data.

## Evidence

Verbatim from https://vercel.com/blog/ai-sdk-5:

> With AI SDK 5, we've rebuilt chat from the ground up. We took the powerful primitives that developers love for working with LLMs and built a world-class UI integration on top, with end-to-end type safety across your entire application.
