Why

The SDK gives Go applications one API for model calls, streaming, tools, structured output, and multi-step agents across supported providers. It follows the design of Vercel’s AI SDK and stays wire-compatible with its TypeScript frontend hooks. A Go endpoint can stream Server-Sent Events (SSE) directly to hooks such as useChat.

   Go backend                          React frontend
   ──────────                          ──────────────
   aisdk.StreamText(...)   ── SSE ──▶  useChat({ transport })
   aisdk.WriteUIMessageStream(w, …)    // same protocol
