Runway releases open-source Praxis-1 robot control model

Runway has released Praxis-1, a robot control model built on video pretraining, with open weights and source code under the Apache 2.0 license. The model takes camera images, text instructions and robot position data, predicts how the scene will change and derives matching robot movements, and it scored a 46.2 percent success rate on Nvidia's RoboLab-120 leaderboard, ahead of FLUX 3 Action at 42.9 percent. Runway ran all tests itself and the results have not been independently verified; the base model needs an 80 GB GPU and further training before working with new robot systems.
