使用 FastAPI 和 OpenAI 构建生产就绪的 AI 后端

Many developers today utilize ChatGPT, but the real value in practical systems lies in integrating AI into a reliable backend. While connecting to the OpenAI API is straightforward, production environments present challenges such as slow response times leading to user drop-off, uncontrolled token usage with unpredictable costs, and AI logic becoming a black box. This project addresses these issues by building a manageable, production-oriented AI backend using FastAPI, featuring a simple yet practical AI backend API that includes a FastAPI-based endpoint, OpenAI API integration, and a clean JSON response design.
