MMPCBench - Diagnostic Precision: leaderboard

MMPCBench (arXiv 2608.29286v1, Table 2): proactive critique of flawed multimodal inputs for 14 MLLMs; a judge panel of GPT-5.2, Gemini-3-Pro and Claude-Sonnet-4 scores the responses, and two of those judges are also evaluated. Mean judged precision of the diagnosed root cause on detected errors only, 0 (irrelevant) to 2 (precise); higher is better.

Metric: Judge-panel score (0-2; detected errors only). Source: arxiv.org. Saturation forecast: Estimated already saturated. 14 models tracked.
