GapEval - Numerical Perception (Understanding): leaderboard
GapEval (Wang et al., 2026) poses bidirectional multimodal questions that a model can answer in text or with a generated image; these boards score the text answers. Numerical perception: count the two kinds of object in an image and state the counts swapped. Accuracy in percent, judged correct or incorrect by GPT-5-mini against a reference answer and averaged over ten sampled runs; higher is better.
Metric: Accuracy (%; count two object types in an image and state the swapped counts; text answers to GapEval's bidirectional questions, judged correct or incorrect by GPT-5-mini against reference answers, mean of ten sampled runs). Source: arxiv.org. Saturation forecast: Around October 2027. 15 models tracked.
