别再混用这三个术语了。这篇文章清晰拆解提示工程、循环工程和图工程各自管哪一层，面试和写简历都能用上。
文章对比了提示工程（Prompt Engineering）、循环工程（Loop Engineering）和图工程（Graph Engineering）三种AI工程方法。循环工程于2025年末进入AI词汇，到2026年6月主导开发者讨论，图工程约六周后出现。三者并非竞争技术，而是在不同抽象层次上改变AI工作流。提示工程聚焦单次指令优化，循环工程引入多步迭代，图工程构建结构化依赖关系。
Prompt Engineering vs Loop Engineering vs Graph Engineering: What Changes at Each Layer
Three terms now compete for the same line in AI engineering job descriptions. Prompt engineering is the established one. Loop engineering entered the AI vocabulary in late 2025 and dominated developer discussion through June 2026. Graph engineering followed roughly six weeks later. They get used interchangeably. Should they be? The three are not competing techniques. […] The post Prompt Engineering vs Loop Engineering vs Graph Engineering: What Changes at Each Layer appeared first on MarkTechPost .
