MathVista (OpenVLM)
Multimodal
MathVista's testmini split, mathematical reasoning over figures, charts, and diagrams, mixing multiple-choice and free-form numeric answers. Scored by the OpenVLM Leaderboard, which runs every model through OpenCompass's VLMEvalKit under one fixed harness. That is a different measurement protocol from the lab-reported and Artificial Analysis runs of the same underlying benchmarks, so it forms its own factor group. No evaluation_item_count is declared: the leaderboard publishes scores to one decimal place, which is coarser than the item lattice, so the denominator cannot be confirmed from the numbers and a binomial noise model is not claimed.
