WUJI(@wuji_global):Huge congrats to @DynaRobotics on Dyna-2. 1M+ hours of egocentric human video. No robot data during pre-training. Scaling still shows up on unseen robot data and real-robot evaluation. Great to see Wuji Hand used in the real-robot demos. We'll keep building dexterous robot hardware with ecosystem partners to bring general-purpose robots closer to real-world deployment. #WujiTech #WujiHand #Dyna2 #Robotics #WorldModels

Today we are introducing Dyna-2, a world-action model pre-trained on one million hours of human video. At this scale, for the first time, we discovered several new scaling laws: • world-action models exhibit scaling law on human data across four orders of magnitude, from 1000 to 1,000,000 hours, • this human data scaling law implied a scaling law on never seen robot data, • both data and objective matter; world modeling and scaling on video data are essential for cross-embodiment scaling transfer to emerge 🧵
