作者 | sunnyzhao 编辑 | 大模型之心Tech 1，planing阶段带来了巨大的耗时，当tool变多后，turbo系列模型的准确率堪忧，因此不得不使用旗舰模型，这让延时进一步增 加。 2，planing的质量不够高，原来的task bot做任务所使用的workflow是人工决定的，现在改成了模型自助决定，从目前的测试来 看，由模型构建的复杂工作流的可用率远远不及人类水平。简单工作流使用判别式小模型反而性能更好。 3，reflection是一种时间换准确度的策略，然而这个策略非常容易重复进行自我内耗，和死循环。 这几个问题，确实是目前AI Agent技术的通病。如果把Agent当成"LLM+工具调用"的简单组合，没有认真处理工程细节，实际的 效果也确实未必比工作流编排就更好。主要结合看到一些论文，和一点实际经验，按题主说到的三点谈一下自己的看法。 本文只做学术分享，如有侵权，联系删文 ，自动驾驶课程学习与技术交流群事宜，也欢迎添加小助理微信AIDriver004做进一步咨询 Planning慢的本质原因 原文链接： https://www.zhihu.com/question/657739588/ ...
