MotionHalluc - Attributional Hallucination: leaderboard

Choosing which of two corrective instructions names the right joint and direction of the motion difference (600 questions). MotionHalluc (Guo et al., 2026) tests whether multimodal models compare a query and a reference fitness-exercise video (553 pairs from Fit3D) without hallucinating motion differences; open models decode greedily and API models are averaged over three runs. Accuracy in percent; higher is better.

Metric: Accuracy (%; choose the one of two corrective instructions that names the right joint and direction; 600 questions). Source: arxiv.org. Saturation forecast: Around February 2027. 5 models tracked.
