CPEN RouterOpenAI-compatible routing with live price caps
Rankings

Compare CPEN routes by GPQA Diamond, price, speed, and status.

Benchmarks currently use GPQA Diamond only. Buyers should compare input/output price, GPQA score, reasoning profile, status, success rate, and p95 latency together.

Only GPQA Diamond is shown. Routes appear only after a successful GPQA Diamond run. Status combines success rate, p95 latency, and benchmark risk flags.
