DYNA-2 is Dyna Robotics' world-action model pre-trained on over 1 million hours of egocentric human video (~170 years), using a human-to-robot transfer scaling law to achieve an 87% zero-shot pass rate at customer sites versus 46% for Dyna-1. It enables robots to complete end-to-end workflows in hospitality, logistics, and factory operations, with each deployment strengthening the fleet and scaling from one site to hundreds.
