Jev is literally the FASTEST model ever built I built a stack that runs agents 200x faster and 400x cheaper than the standard Claude Code loop. Not average. Best case, on the tasks where a $9 model was doing $0.0004 work the whole time. Split reasoning from decision making, put Jev in front of every classify, route, or approve call, and only let Claude Code touch the tasks that actually need it to write something. How to build it from scratch, the full architecture, the PR review example that dropped from 24 seconds to 11.8, the exact confidence thresholds I use. Full breakdown below. follow @cyrilXBT
