GWM Worlds 2 is Runway’s research preview for interactive worlds. The autoregressive diffusion model generates continuous 720p video at 24 frames per second with synchronized 48,000 Hz audio. Text actions change the scene, subjects, and camera motion during the simulation.
Runway describes a continuous world without a fixed clip duration. Its video and audio input claims are contradictory. One demonstration continues an eight-second video with audio, while the limitations section rules out those inputs. Image references beyond the first frame are unsupported. General API access is not confirmed.
Specifications and access

|---|---|
| Model class | Interactive audio-video world modelSource |
| Video | Continuous 720p video at 24 frames per secondSource |
| Audio | Generated audio at 48,000 HzSource |
| Interaction | Text actions control the scene, subjects, and camera motion in real timeSource |
| Access | Research preview with a contact form, no confirmed general API accessSource |
| Limitations | No image references beyond the first frame; imperfect long-term memory and detail degradation with fast camera motionSource |
| Video and audio inputs | Provider claims are contradictory. Runway demonstrates continuing an eight-second video with audio, but lists prefilled video and audio as unsupported in its limitations. The exact scope remains unresolved.Source |
