Ethan Mollick 指出预分类路由器（pre-classifying routers）会导致糟糕结果，因为路由本身很难，且常低估智能的价值。OpenAI 在 GPT-5 上已吃过亏，如今这类思路又热起来。引用的 @MParakhin 也认为，用预分类器先判断任务是否简单再调用小模型看似省钱省延迟，但可靠执行必须先解决任务本身，唯一可行的是 advisory model approach。
Yes！ Pre-classifying routers are going to going to result in a lot of bad work because routing is hard and tend to underestimate the value of intelligence on many problems. OpenAI learned this with GPT-5， now it seems routers are hot again.
I have this struggle with my own teams, too: many think it is a great idea to save money/latency/sanity by running a pre-classifier: "This task is simple, use a...
