Runway introduces Praxis-1, an open-weight world action model for robots

The Robot Report reported on 2 October 2026 that Runway has introduced Praxis-1, an open-weight world action model that turns its large-scale video pretraining into robot control. Runway's CTO said the model learns mostly from third-person video rather than scarce robot demonstrations. Runway says it is still testing across embodiments before general availability.

What it means If video-pretrained policies scale as claimed, the robot-data bottleneck eases, and open weights let labs test that claim themselves.
