Pairs are drawn from the top 50 models by Known Good Index and every pair has exactly one page, ordered alphabetically by slug. Figures on each page are aggregated from published sources — pricing and provider telemetry from OpenRouter, metadata from models.dev, evaluation scores from their publishers. We do not run our own evaluations.
