Vercel 推出 AI SDK 3.0：支援 Generative UI，讓 AI 直接生成 React 元件

Vercel has officially launched AI SDK 3.0, a major version update that introduces the groundbreaking concept of "Generative UI." Previously, when building AI chat interfaces, large language models (LLMs) could only return plain text or Markdown. To render complex UI elements — such as charts, cards, or interactive forms — developers had to instruct the model to output structured JSON data, then have frontend code parse that JSON and manually render the corresponding components.
