CPEN RouterOpenAI-compatible routing with live price caps

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

Input value score = GPQA² ÷ input $/1M, normalized so the best row in this table is 100. Success rate, output price, and total token cost are excluded from the score.

Filters narrow the table and chart together.

GPQA 80+ input-cost frontier

High-range price frontier for GPQA 80+. Higher is smarter; further left is cheaper input cost.

1M / 10M / 100M = monthly input tokens used for the X-axis cost estimate.
