FineART pairs dense subtask labels across 40,543 episodes with a single policy that predicts the next language instruction and conditions bimanual actions on it. After ALOHA mid-training and fine-tuning on five YAM task types, it completed held-out prepare-breakfast sequences in 28% of rollouts, with 78.3% average progress; this shows transfer after YAM fine-tuning, not zero-shot transfer or reliable autonomous completion.
