K9-Bench - Open-Ended Overall Quality: leaderboard

K9-Bench also scores free-form answers to its canine video questions with a GPT-4o judge, which rates overall response quality on a zero to ten scale that is rescaled to 0-100. The judge sees the question, the reference answer and the model answer, and also rates logic, factuality, conciseness and accuracy separately.

Metric: Overall response quality (0-100): GPT-4o judge rating, on a 0-10 scale rescaled to 0-100, of the overall quality of each free-form answer to the K9-Bench video questions; 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. Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
