EPAG - Top-k 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 a ranked list of diseases from the collected history. Share of cases where the gold disease appears anywhere in that list, in percent; higher is better.

Metric: Disease Diagnosis Accuracy, Gold Anywhere in Ranked List (%). Source: arxiv.org. Saturation forecast: Estimated already saturated. 11 models tracked.
