FeynmanBench - Propagator Inventory: leaderboard
Metric: CP2 pass rate (%), the complete list of internal lines with particle types and multiplicities, checked by rule-based scripts, on FeynmanBench's Feynman-diagram tasks (a rendered diagram plus minimal conventions; Standard Model QED, electroweak and QCD diagrams from tree level to two loops), API models at temperature 0, mean of five runs; four models ran on subsets of 165 to 742 items, the others on about 2,000; higher is better. Source: arxiv.org. Saturation forecast: Not forecast. 19 models tracked.
