Vercel AI SDK 3.1: ModelFusion joins the team

This post introduces Vercel AI SDK 3.1, which includes AI SDK Core, AI SDK UI, and AI SDK RSC. AI SDK Core provides a unified, ORM-style API for LLMs, abstracting provider differences and supporting text generation and structured object generation with Zod schemas. AI SDK UI offers framework-agnostic hooks for building chat interfaces quickly. AI SDK RSC introduces `streamUI` for generating component-based interfaces beyond text, building on the AI SDK Core's capabilities and supporting tools and tool calling.
