Assumes eval-gated routing: the cheaper model must clear a per-workload quality floor before traffic moves. Where evals fail, the spread narrows — this is an estimate, not a quote.

This delta is an estimate until it's verified against your own traffic.

A shadow-mode audit mirrors a week of real traffic and returns a verified per-use-case number — nothing changes in production.
