Act2Answer - Attribute: leaderboard
Act2Answer (Kachaev, Moskalenko et al., 2026) turns two-option knowledge questions into short Simpler tabletop episodes in which a vision-language-action policy answers by placing a cube on one of two image tiles; each item runs in its original and left/right-swapped layout. This category compares a visual attribute of the objects in two photos, from MLLM-CompBench: 150 items, 300 episodes. The score is the percentage of episodes ending on the correct tile (chance 50); higher is better.
Metric: Soft success rate (%; 150 binary-choice items from MLLM-CompBench, 300 episodes; answer by placing a cube on the chosen image tile in a Simpler tabletop episode, original and left/right-swapped layouts, chance 50).
