Pro2Bench - Intervention Timing: leaderboard

Metric: Geometric mean of the interrupt-class and silent-class F1 (G-Mean F1, 0-1 scaled to %) for deciding when to speak; zero-shot monolithic assistant (8 uniformly sampled frames per clip, greedy decoding for the interrupt or silent decision), mean over the six evaluation sets (EgoExo4D, EPIC-KITCHENS, HowTo100M, Ego4D, HoloAssist, EgoProactive); higher is better. Source: arxiv.org. Saturation forecast: Around 2030. 6 models tracked.
