ATOM-Bench - Single-Arm Composition: leaderboard

Held-out compositional manipulation on a real Franka Panda arm from ATOM-Bench (Wu et al., 2026): 12 tasks that each combine motor skills (pick-and-place, reorienting, pushing, stacking, pouring, opening a drawer) with two or more language constraints (color, shape, size, count, exclusion, spatial relation, destination), none of them demonstrated during fine-tuning. The policy is fine-tuned only on the benchmark's atomic tasks; success rate in percent over 10 fixed physical test seeds per task, macro-averaged over tasks; higher is better.

Metric: Success rate (%; held-out Composition Set, 12 tasks x 10 fixed physical test seeds on the Franka Panda single-arm track, macro-averaged over tasks; one policy fine-tuned on the 15 atomic tasks of the track). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 5 models tracked.
