Runway introduces Praxis-1 world action model for robotics

Runway AI has introduced Praxis-1, an open-weight world action model that uses video pretraining to enable robots to perform tasks. Rather than relying on scarce and expensive robot demonstration data, Praxis-1 learns from abundant third-party video to understand how objects behave and tasks unfold, with performance improving as more video data is available. The company has tested Praxis-1 with early partners across different robot types and is planning to release it publicly with open weights in the coming months. This approach addresses a key limitation in robot training, which has historically been bottlenecked by the scarcity of real-world robotics data.
