把 Jev 接进探索步骤做元素选择
作者把 Jev 用于遍历实时应用、选择下一个交互元素，路由、筛选、压缩取舍这类分类任务不再走语言模型，更快也更便宜。
JEV MADE A WHOLE CATEGORY OF PROMPT ENGINEERING POINTLESS IN A WEEK not the hard parts. the parts nobody should have been paying a frontier model for in the first place. routing. picking. filtering. deciding what survives a compaction. every one of those is a classifier we dressed up in a system prompt because that was the only tool on the desk. a model that cannot write one sentence does them 200x faster, 400x cheaper. we wired it into our explore step this week - it walks a live app and chooses the next element, no language model in the loop. it got faster and it got more boring, which is the point. the uncomfortable part: it is right more often and it can never tell you why. would you let something that cannot explain itself decide what your agent touches next?
