Integrates 3D spatial supervision into continual pre-training for robot vision-language-action policies, helping spatial understanding transfer to downstream tasks. Across eight real-world deployment conditions, it improves average success over π0.5 by 24 percentage points.
Predicts structured geometry such as bounding boxes and robot trajectories in parallel, rather than generating coordinates one at a time. It reduces errors on evaluated robot-planning tasks while cutting decoding time.
A realistic video is not proof of a modeled world. The paper defines world models through persistent state, intervention-conditioned dynamics, and feedback, then presents infrastructure for reproducible inference and evaluation across video, 3D/4D, and embodied systems.
