Jev 用法清单：用廉价判断过滤昂贵推理
作者列举 Jev 在代码检索、邮件分流、工具调用、RAG 过滤等场景中先做便宜判断、再决定是否调用大模型的六种用法。
finally got to knw wat is Jev🥳🥳 Jev is getting interesting. Not because it replaces the big models. Because it can make you stop calling them for everything. Imagine: → Your coding agent gets 500 files Jev picks the 8 worth deeper analysis. → Your inbox gets 2,000 emails Jev decides what deserves an LLM. → Your agent wants to call a tool Jev asks: “Is this action actually necessary?” → Your RAG retrieves 50 chunks Jev kills the irrelevant ones before they hit the expensive model. → Your production system throws 10,000 events Jev finds the few that deserve attention. → Your AI memory wants to save everything Jev asks: “Will this matter later?” The pattern is simple: Cheap judgment → expensive reasoning only when needed. Maybe the future isn’t one giant model doing everything. Maybe it’s thousands of tiny decisions deciding when the giant model gets involved.
