World Models for Physical Interaction
Runway Praxis-1 is an open-weight foundation model designed to understand physical dynamics, causality, and robotic motor control within 3D spatial environments.
Architecture and Robotics Benchmarks
Unlike pure video synthesis, Praxis-1 models world actions and physical consequences, enabling robots to simulate manipulation tasks before physical execution.
Availability Window
Formally announced by Runway Research, open weights and code repositories are scheduled for public release in the fourth quarter of 2026 (2026-Q4).
