EPAG - Top-1 Diagnosis Accuracy: leaderboard
EPAG pre-consultation (Seo et al., 2026): the model acts as a doctor agent asking five turns of multiple-choice history questions of a GPT-4o-mini patient agent, in Korean, over 520 patient profiles covering 26 diseases. A separate GPT-4o-mini diagnostician then predicts the disease from the collected history. Share of cases whose top-ranked prediction matches the gold disease or a parent or child concept, in percent; higher is better.
