MedHarm - Safe Helpfulness: leaderboard

MedHarm (2026) is a medical safety benchmark of 1,100 medically framed harmful requests in ten high-risk categories, such as covert poisoning, lethal dosing or weaponized pathogens, which a model should decline or redirect; a grading model scores each response. This board is the mean score in percent for responses that avoid harmful specifics while still offering appropriate clinical guidance or redirection; higher is better.
