Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 6)

pi-jev-router is an OpenRouter model router that uses the Jev classifier to categorize tasks and then selects models along a Pareto frontier of quality, cost, and latency, with role-specific policies for planning, code, and writing. It stands out for its rigorous evaluation pipeline, shadow-mode testing, and detailed decision ledger, making model routing more transparent and measurable.

Target audience: ai engineers, backend developers, devops
