Jev plus Opus 5.5 cuts daily fork cost from $110 to $4
A case study says Jev handles forks like picking which notes to load, delegating trivial steps, choosing recovery paths and ordering checks, while Opus only does hard reasoning, saving about $106 a day.
a Google engineer runs his whole day's work in 2 hours instead of 6-8 with this setup Jev + Claude Opus 5.5 forks go from $110 a day to $4 the moment Jev takes them over what Jev lifts off Opus: -> picks which project notes are worth loading -> hands the trivial steps to a faster worker -> chooses the recovery path when a tool breaks -> fires the narrow checks first, saves the full suite for last Opus stays on the hard reasoning Jev only picks between options the harness already built and tested every call lands in about 100 ms, output tokens are free Jev engineering in one line: the expensive model thinks, the cheap one decides $106 a day saved and 4 hours of your life back is the number your manager remembers at review read the paper, then the full Jev guide below
