What was announced
Runway introduced GWM Worlds 2 as a research preview on September 3. The company describes responsive generation at 720p and 24 fps with 48 kHz audio, using scene instructions, subject actions and camera inputs. These figures are the developer’s claims. I have not tested the system.
What it means for direction
Runway’s research page also acknowledges imperfect long-term memory and degradation during difficult camera movements. These limitations affect the consistency of the generated world over time. A responsive image and a persistent environment are related but distinct achievements; the preview does not establish that both have been solved.
