Jev takes over Opus 5.5 branch decisions, cutting daily cost from $110 to $4
The author says letting Jev rank notes, hand off easy steps, pick recovery paths and choose tests while Opus handles hard reasoning saves about $106 a day on the same work.
Jev + Claude Opus 5.5 is a f*cking goldmine... i can't understand why everyone isn't wiring this up yet the forks alone drop from about $110 a day to $4 once Jev takes them over. right now it's the best way i know to run Opus where Jev steps in: -> ranks which project notes matter before the context loads -> passes the easy steps to a faster worker -> chooses a recovery path when a tool fails, so nothing retries blind -> runs the targeted checks before the full test suite Opus does the hard reasoning. Jev chooses between options the harness already built and checked every choice comes back with a probability, so the harness can set a confidence floor and push anything below it back up to Opus Jev engineering fits in one line: the expensive model reasons, the cheap one decides $106 a day saved on the same work ends up in your performance review start with the paper, then the full Jev guide below
