### Maintainer results on GPT-4o response pairs

JudgeBench’s paper and maintained leaderboard report judges under different prompts, reasoning efforts, and response-model splits. Accuracy is a percentage. The paper’s 700-pair GPT-4o split is distinct from the 270-pair Claude split. The app appends the same Nemotron CSV to both tabs without specifying a response split; we show that supplement once with its split unresolved. Live one-decimal values and paper two-decimal values are preserved separately.

GPT-4o-2024-05-13 response split. The public app rounds to one decimal; paper tables retain two decimals.
