GroupToM-Bench - Intention: leaderboard
GroupToM-Bench (2026) tests group-level theory of mind in multimodal models: 240 expert-seeded multi-agent scenarios, each a scene image with dialogue, are probed along a seven-level audit from individual mental states to collective outcomes. This board is level 3 intention prediction. Scored by strict exact-match accuracy in percent on multi-select multiple choice (random 6.7); higher is better.
Metric: strict exact-match accuracy (%) over multi-select options (random 6.7) on Level 3 intention prediction (the behavioural strategy an agent will adopt), multiple choice; 240 multimodal multi-agent scenarios (scene image plus dialogue); higher is better.
