Metric: pairwise accuracy (%) on the 238 pairs where the rejected chain has an injected logical-reasoning fallacy but the same correct final answer, M-JudgeBench (3,712 multimodal judge pairs from MMMU, MMMU-Pro, MMStar, MMReason, M3CoT, MathVision and MathVerse; the model sees the image, question and two responses and outputs its choice directly, open-source judge models with their own prompts); higher is better.
