Dyna Robotics Introduces Dyna-2 Trained on Million Hours of Video

Dyna Robotics posted that it is releasing Dyna-2, a world-action model pretrained on one million hours of human video. The company stated that this scale revealed new scaling laws for world-action models on human data across four orders of magnitude, from 1,000 to 1,000,000 hours, and that the human data scaling transfers to robot performance. Separate posts from engineers at other humanoid and bimanual robot firms said world-action models have solved core manipulation tasks, moving the remaining bottleneck to running the models at high enough frequencies for real-time control.
