Act2Answer - Traffic: 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 asks the policy to pick the board whose traffic sign matches the instruction, from VL-Think (24 concepts): 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 VL-Think, 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). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 6 models tracked.
