grok-jev-reflex：Grok 规划、Jev 做廉价判断
开源路由器让 Grok 4.7 负责规划，Jev 在中间做便宜的 yes/no 决策，把每次 25 个工具砍到 8 个、首轮 token 从 17.8k 降到 9.5k，账单最多省 40%。
grok 4.7 thinks. jev reacts. together, one ai agent now thinks twice before every move, and pays a fraction of the price for it. grok-jev-reflex is a free, open source router that pairs the two: grok 4.7 plans and acts, jev makes the cheap yes/no calls in between, at $0.042 per million tokens, answered in about 239ms. > 25 tools sent on every call, cut down to 8 > first prompt: 17.8k tokens → 9.5k tokens > bill: up to 40% less, same speed > numbers measured independently on xAI's grok build setup is 5 messages, no code, about 7 minutes: make a key, install, add one rule, run a shadow day watching only, then go live. jev can only make the agent do less or ask more, it can never approve anything irreversible on its own. 100% free. open source.
