Production

前言 # 2026年，大语言模型已经深度融入各种生产系统。从 Claude 4 Opus 到 GPT-5 Turbo，从 Gemini 2.5 Pro 到 DeepSeek-V4，开发者有了前所未有的模型选择。然而，在生产环境中调用这些AI API远非简单的 fetch 请求那么简单。

Introduction # In 2026, large language models are deeply embedded in production systems across every industry. From Claude 4 Opus to GPT-5 Turbo, from Gemini 2.5 Pro to DeepSeek-V4, developers have an unprecedented selection of models at their fingertips. But calling these AI APIs in production is nothing like a quick notebook experiment. This article distills 10 hard-earned lessons from real production incidents. Each one comes with a war story, a solution, and runnable code. Hopefully you won’t have to learn these the hard way.
