Runway and NVIDIA just previewed a real-time HD video model running on Vera Rubin at GTC, pushing time-to-first-frame latency under 100 milliseconds. The speed is aimed at powering Runway's General World Model, GWM-1, pointing toward truly instant and interactive AI simulation, though it is currently strictly a research preview.
Runway just announced GWM-1, its first family of general world models built on Gen-4.5 that generates frame-by-frame simulations in real time. It reacts to camera movements, audio, and robot actions across three specialized versions for explorable worlds, interactive avatars, and robotics. Why it matters: robotics teams can now test policies and generate counterfactual data inside a video diffusion simulator before touching physical hardware.
