Runway
GWM Worlds 2
Released Sep 3, 2026
Runway's real-time interactive world model that turns video-and-audio generation into a steerable simulation: users define environment, subjects, style, physical rules and ambience, then steer with free-form text actions and continuous camera motion.

Strengths & weaknesses
Strengths
- Continuous 720p video at 24 fps with generated 48 kHz audio, including matched speech and lip movement
- No preset session length; Runway says it 'can generate indefinitely'
- Free-form text actions addressed to subjects or the scene, bindable to keys
Weaknesses
- Research preview gated behind a contact form; no pricing or API
- Runway notes real-time generation trades fidelity for speed; fast camera rotations degrade detail
- Long-term memory is imperfect
maxSessionSec null because Runway states sessions have 'no preset length' rather than a cap. Image input = a first frame (image references beyond the first frame not supported). Builds on GWM-1 (2025-12-11; GWM Worlds/Avatars/Robotics variants) — GWM Worlds v1 not added separately; its current availability is not stated on Runway's pages. openWeights false = none mentioned.
