Runway GWM Worlds 2 is a research preview from Runway of a real-time, interactive world model that generates a steerable environment as you play it. You define the scene, subjects, visual style, and physical rules, then drive the world with text actions aimed at any character or the scene itself, alongside continuous camera motion. Unveiled on September 3, 2026, it is not a clip generator, because sessions have no preset length and the world evolves from your input.
Core Features
- Generates continuous 720p video at 24 fps with synchronized 48,000 Hz audio, live.
- Uses a WorldPrompt format splitting persistent scene context from a timestamped event stream.
- Supports agent control: give a goal and an agent steers a subject to achieve it.
- Demonstrates real-time multiplayer, with different users steering different subjects.
- Can prefill from an existing video and continue playing with consistent world and audio.
Use Cases
- Game and virtual-production teams prototyping explorable environments fast.
- Previz artists testing camera and lighting ideas inside a reactive scene.
- Robotics and embodied-agent researchers using it as a simulated training world.
Pricing
GWM Worlds 2 is a research preview with access gated behind a contact form while Runway validates it with select partners. It is not a self-serve paid product yet, so treat pricing as available on request rather than a published tier.
Pros and Cons
- Pro: Real-time, steerable worlds with native audio are a genuine step past clip generation.
- Con: Access is gated and on-the-fly rendering still shows fidelity trade-offs, so it is a preview, not production.
Our Take: Best for studios exploring interactive, playable worlds; the trade-off is that fidelity and consistency still vary because everything renders on the fly, so it is a capability preview, not a shipping production tool.
