Beijing Academy of Artificial Intelligence (BAAI) released Orca, a world model predicting abstract world states instead of tokens or pixels. Trained on 125,000 hours of unlabeled video, it matches the specialized system π0.5 on five robot tasks without any action labels. This approach could alleviate the chronic shortage of annotated data in robotics, offering a cost-effective path for model development. For researchers in robot perception and control, Orca provides a new way to build effective world models without expensive labeling, potentially lowering entry barriers and accelerating research.
