Vercel AI SDK 3.1: ModelFusion joins the team

Vercel has released AI SDK 3.1, which includes ModelFusion joining their team. This release brings them closer to delivering a complete TypeScript framework for building AI applications. The AI SDK is organized into three main parts: AI SDK Core, AI SDK UI, and AI SDK RSC. AI SDK Core provides a unified API for generating text, structured objects, and tool calls with large language models (LLMs). AI SDK UI offers framework-agnostic hooks for quickly building chat interfaces. Lastly, AI SDK RSC is a library to stream generative user interfaces with React Server Components (RSC). The release also includes support for OpenAI, Anthropic, Google Gemini, and Mistral model providers.
