Model Routing Guardrail
Queries over-spending on premium models. Routes to the cheapest that clears the bar.
A workload runs on a premium model while a cheaper one clears the quality bar on that workload in the eval harness.
Routing policy updated in the Ward layer against the workload; eval results and the promotion decision logged.
Every write is gated on an approver role you name. Nothing runs unattended.
- Score every candidate model against the workload on your own evaluation cases, not on public benchmarks.
- Find the cheapest model that clears the quality bar for that specific workload, which varies by workload far more than by vendor.
- Shadow the change before promoting it, so the comparison is on live traffic rather than a fixture.
- Promote through the same review as any other config change, with the eval delta recorded.
- Close when cost falls and eval scores hold for a full week of live traffic.
Cost per query for the workload with the eval score held within tolerance. A cost win with a quality loss is a rollback.
The case closes on this number, not on the action being taken. A playbook without a close condition is a dashboard.
