GWM-1 (General World Model-1) from Runway represents a major advancement in AI-driven simulation, enabling real-time, interactive generation of coherent worlds with physics-aware behavior. Launched in December 2025 as Runway’s first world model family, GWM-1 builds on Gen-4.5 to create persistent, controllable environments for creative, robotic, and avatar applications.
What Is GWM-1 by Runway?
GWM-1 is Runway’s family of autoregressive world models that simulate reality through frame-by-frame prediction, incorporating physics, geometry, lighting, and causality. Unlike traditional video generators, it produces interactive, persistent simulations controllable via actions like camera movement, robot commands, or audio.
For beginners, GWM-1 is accessible via Runway’s web app: Provide a prompt or image, and explore a generated world in real-time at 24 fps (720p).
Intermediate users experiment with variants for specific tasks, such as avatar conversations or robotic data.
Advanced developers use the Python SDK (for Robotics) or API for custom integrations, leveraging tool calling for agentic systems.
GWM-1 variants include Worlds (explorable spaces), Robotics (synthetic training), and Avatars (conversational characters), with plans for unification.
The Evolution of GWM-1
Runway’s journey in generative AI led to GWM-1, built atop Gen-4.5 (top-rated video model).
Announced December 11, 2025, GWM-1 entered the “world model race” alongside Google Genie-3 and others.
Initial release focused on real-time coherence; early 2026 emphasizes SDK availability and enterprise talks for Robotics/Avatars.
This positions GWM-1 as a bridge from video to simulation.
