MMStar (OpenVLM)
Multimodal
MMStar is a curated multiple-choice benchmark of vision-indispensable samples, filtered so that questions cannot be answered from text alone. The native VLMEvalKit MMStar.tsv has 1,322 four-choice, 85 two-choice and 93 three-choice questions; uniform guessing among actual options gives 26.933333333333334 percent. Literal none/None answer choices remain candidates. Scored by the OpenVLM Leaderboard through one fixed VLMEvalKit harness, separately from lab-reported and Artificial Analysis protocols. Published scores are rounded to one decimal place; run-specific coverage remains unverified, and the existing null count is retained pending separate observation-denominator handling.
