Dyna Robotics Releases Dyna-2 World-Action Model Pre-Trained on 1 Million Hours of Video

Dyna Robotics unveiled Dyna-2, a world-action model for robot manipulation pre-trained on over 1 million hours of egocentric human video—equivalent to approximately 170 years of continuous waking experience. The model demonstrates a scaling law for human video data and represents the first successful transfer of such scaling to unseen robot data, with evidence that video prediction drives this transfer. Dyna-2 is deployed as a vendor-operated system through Dyna robot cells rather than as downloadable weights or an API, addressing the traditional bottleneck of action-labeled training data by leveraging ordinary human video to train robots for manipulation tasks.
