MMRareBench - Diagnosis: leaderboard

Metric: Diagnosis track (T1) score: open-ended primary diagnosis from a masked rare-disease case narrative and its medical images, graded 0-100 by a Qwen3-VL-235B judge with a strict track-specific rubric that awards credit only when a criterion is fully met (exact match weighted three times disease category and specificity, capped at 20 without an exact match); higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 23 models tracked.
