KnowHal: leaderboard

KnowHal (Shandong University, 2026) evaluates hallucination in multimodal LLMs with paired questions over 1,800 entity images in 10 domains: a positive question about evidence that is present and a negative question carrying a false premise, across entity, attribute, relation and knowledge dimensions. The overall score is the mean of positive and negative accuracy in percent; higher is better.

Metric: Overall score (%; mean of the positive-question and negative-question average accuracies; 1,800 entity-image samples in 10 domains with paired positive and false-premise negative questions; positive answers scored by standard VQA answer normalization and soft matching, negative answers by a GPT-4o-mini judge (option matching for relation questions); zero-shot).
