VERHallu - Causal QA: leaderboard

VERHallu (Zhang et al., 2026) probes event-relation hallucination in video LLMs with clips from Mr. Bean films and episodes, whose counterintuitive event chains defeat language and vision-language priors. The 497 causal questions ask why a person performs an event, with seven options including distractors built from language and vision-language priors; accuracy in percent, higher is better.

Metric: Accuracy (%; 497 seven-option questions on why an event happens, distractors from language and vision-language priors; random 14.3; each model's own frame sampling and default settings, answer given as the option number). Source: arxiv.org. Saturation forecast: Around February 2027. 18 models tracked.
