MoHallBench - Sequential Inference Hallucination: leaderboard

Tests whether video LLMs assume a sports or everyday motion reached its expected ending when the clip stops before it, 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; sequential inference hallucination on clips truncated before the terminal sub-action). Source: arxiv.org. Saturation forecast: Around December 2027. 10 models tracked.
