About jev-codex-router

Jev Codex Router Per-turn model routing for Codex, driven by Jev (TypeSafe System One). Every turn is classified by Jev and served by the cheapest model that can handle it, at a thinking depth adapted to the task — instead of running everything on the frontier model. The decision costs ≈ $0.00003 and ≈ 0.6 s per turn. Measured savings: ≈ −60 % vs a full-frontier baseline on a 7-day replay of 237 real turns — protocol, tables and limitations in BACKTEST.md.
