GT-HarmBench - Battle of the Sexes: leaderboard

Metric: Utilitarian accuracy (%) on the 141 Battle of the Sexes scenarios: share in which the pair of choices maximizes total welfare; self-play: two copies of the model each read their side of a natural-language high-stakes scenario built from the MIT AI Risk Repository and choose an action independently, with no communication; reasoning at medium where available; a propensity to choose the socially optimal joint action, not task accuracy; higher is better.
