Vision language models answer 168 multiple-choice problems from the 2025 Math Kangaroo, given as screenshots across six grade groups. Many problems need reading a diagram.

Models score lower on problems for grades 1 to 6 than on those for grades 7 to 12. MathArena ran 23 models and later marked the set deprecated.

GPT-5.5 leads with 94.9% among models released by July 2026

Best score per model from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best. Every run is in the next chart.

GPT-5.5 leads with 94.9%, claims included

Best score per model from every source, including labs’ own numbers and claims Epoch AI collected from reports and papers. Labs pick their own settings, so a claim can beat an independent run of the same model.

The newest model with a score here came out in July 2026, and nobody has tested a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:
