Praxis-1 turns video pretraining into an open robot-control model
Runway is testing Praxis-1, an open-weight model that lets robotics developers train control policies from large-scale video instead of relying only on scarce, costly teleoperated robot data; a public release is planned for the coming months. The model uses video-learned physics and object behavior to choose actions across different robots and environments. In Runway's tests, simulated robot policies predicted real-world results with 0.95 correlation.
