使用 Next.js 16 和 OpenAI 构建流式 AI 聊天(无需 Vercel AI SDK)

📄 中文摘要

许多 AI 聊天教程使用 Vercel AI SDK,但实际上并不需要。通过从头开始构建流式 AI 聊天,可以获得对每个字节的完全控制。跳过 AI SDK 的原因包括:对流中的每个字节拥有完全控制权、提供商无关性(只需更改一个 URL 即可将 OpenAI 替换为 Anthropic)以及更小的包体积(没有额外的依赖)。

📄 English Summary

Build a Streaming AI Chat with Next.js 16 and OpenAI (No Vercel AI SDK)

Many AI chat tutorials rely on the Vercel AI SDK, but it is not necessary. Building a streaming AI chat from scratch allows for complete control over every byte in the stream. Reasons to skip the AI SDK include having full control over the stream, being provider agnostic (easily swapping OpenAI for Anthropic by changing a single URL), and a smaller bundle size without extra dependencies.
