K9-Bench - Cause-Effect Analysis: leaderboard
K9-Bench tests video understanding of domestic dogs: five-option questions about canine posture, action order, scene context, cause and effect, and interaction with people and other dogs, built from real-world web videos with an expert-grounded behaviour ontology. This board covers the questions about what caused a behaviour and what followed from it. Models answer in free form and an answer counts as correct when its embedding is closest to the gold option.
Metric: MCQ accuracy (%; the Cause-Effect Analysis category of K9-Bench, 4,744 five-option questions on 907 real-world dog videos; the free-form CoT answer counts as correct when its Qwen3-Embedding-8B similarity to the gold option exceeds 0.5 and no wrong option is closer; 32 uniformly sampled frames for GPT-4o and the open models, the full video at 1 FPS for Gemini 2.5 Pro and Qwen3-VL-235B-A22B).
