Cultural Moment Benchmark: leaderboard
The Cultural Moment Benchmark (CMB, 2026) evaluates video cultural reasoning on 306 expert-curated concepts from seven Southeast Asian countries in five categories, in three stages per concept. The joint score credits a concept only when its name and its video moment are both chosen correctly, weighted by the temporal IoU of the localized sub-event, in percent; higher is better. Each stage sees the answer the model gave at the previous stage (Carry mode).
Metric: Joint score (%; per concept, 1 if the Stage 1 name and the Stage 2 moment are both correct, times the Stage 3 IoU, averaged over the 306 concepts; 306 expert-curated concepts from seven Southeast Asian countries in five categories (celebrations, dances, games, music, weddings); Carry mode, where the model's own previous-stage answer is carried into the next stage; Gemini, GPT and Qwen read video at 1 fps, InternVL at its native 12 frames). Source: arxiv.org. Saturation forecast: Around March 2027. 6 models tracked.
