Runway’s WorldPrompt and the Engineering of Real-Time Worlds
Runway details WorldPrompt in GWM Worlds 2, a real-time 720p interactive world model at 24 fps.
Runway's research preview GWM Worlds 2 turns its audio-video model into a real-time interactive simulation streamed at 720p and 24 fps with 48 kHz audio. WorldPrompt lets users lock a first frame and issue timestamped actions, including live prompts, without a game-style scripting layer. Runway fine-tunes the base model, converts bidirectional diffusion to autoregressive generation, and uses distillation to cut denoising steps for real-time playback. Executives cite error accumulation and context/memory limits; competitors discussed include DeepMind Genie 3, Odyssey-2 Pro, and World Labs RTFM. Runway was valued at $5.3 billion after raising $315 million.
