Testing a Multi-Model Router: Fallback Chains, Quality-Cliff Detection, and Per-Request Cost Telemetry
pr0h0•
A hands-on walkthrough for testing a multi-model inference router: building ordered fallback chains, detecting the eval-pass-rate quality cliffs where cheaper models silently degrade, and instrumenting per-request token cost and latency telemetry before shipping to production.
