VidPair-Halluc (2026) probes hallucination in video-language models with adversarial pairs of generated videos that share a near-identical background but differ in foreground actions, attributes or event order. This board is the open-ended description score in percent, judged by GPT-4o; higher is better.
Metric: Open-ended description score (%) judged by GPT-4o on VidPair-Halluc adversarial video pairs (generated clips with near-identical backgrounds and different foreground semantics). Source: arxiv.org. Saturation forecast: Around August 2027. 15 models tracked.
