MoHallBench - Scene-Action Hallucination: leaderboard
Tests whether video LLMs affirm an action that the scene makes likely but that does not occur in the clip, using bias-aware paired yes/no queries; from MoHallBench (2026). Q-PairAcc in percent, higher is better.
Metric: Q-PairAcc (%; share of adversarial pairs in which the model answers both the positive and the negative (reversed) yes/no query correctly; 32 uniformly sampled frames, temperature 0; scene-action co-occurrence hallucination, Charades). Source: arxiv.org. Saturation forecast: Around February 2027. 10 models tracked.
