Dyna-2 Proves Scaling Laws for Robotics: 1 Million Hours of Human Video Unlocks Zero-Shot Dexterity (4 minute read)
Dyna-2 is a world-action model (WAM) pre-trained on over one million hours of human video data. Its existence proves that scaling human video data predictably improves zero-shot performance on unseen robot hardware. Dyna-2 achieved an 87% pass rate in real-world zero-shot deployments at customer sites, vastly outperforming the 46% pass rate of its VLA predecessor, Dyna-1. The model uses a new one-step video generation distillation pipeline that drops inference latency by two orders of magnitude for downstream planning.
