SuperRouter

Measure your own product, then route each task to the cheapest model that clears your quality bar. Builds an exam from your product (screens, planted faults, ground truth from those faults). Scores catch rate vs false alarms separately, uses confidence bounds, builds a per-task-type routing table, and serves via an OpenAI/Anthropic-compatible proxy (OpenRouter/Ollama/etc.). Python 3.9+, no runtime deps, Apache-2.0. Works; author-only so far. Product-specific numbers, not a universal leaderboard.
