Anthropic multi-model pipeline: Jev gate kills bad forks in 3 ms
A leaked internal setup uses Opus as orchestrator, Haiku scouts and Sonnet fixers, with a Jev gate routing micro-forks in 3 ms and cutting Opus context from 340k to 2.1k on a 40k-line repo.
Anthropic engineers run Opus 5.5 like this, and it's pure f*cking treasure a leaked internal setup: 1 Opus orchestrator, 12 Haiku scouts, 4 Sonnet fixers, 3 Sonnet breakers and a JEV gate that kills bad forks in 3 ms → Opus 5.5 writes the workflow, then goes idle → Haiku 5.5 audits every module in parallel → Sonnet 5.5 patches each finding in its own isolated copy → Sonnet breakers try to destroy every fix before it's reported → JEV routes the micro-forks, Opus only sees the ones that split the result on a 40k-line repo: 38 findings → 31 survived → 7 refuted Opus context: 2.1k instead of 340k = 162x less the loop: map → scout → patch → break → judge → merge Opus plans. Haiku scouts. Sonnet ships. Nothing merges unbroken. save it, you'll need it ↓
