Worldbuilding

Google previewed Genie 4 demos of explorable worlds with sound, responsive characters and live scene direction. API access is coming soon; early-access users report about 30 seconds of setup for two minutes of exploration.

Creators prompted Claude Opus 5.5 to build 3D scenes in code, score individual visual elements, and revise them iteratively. Reported outputs include a Three.js ship scene and an explorable Atlantis world built in about two hours.

Runway says GWM Worlds 2 generates continuous interactive 720p video at 24 fps with 48 kHz audio. WorldPrompt separates persistent world rules from changing actions and events.

Hailuo says a team adapted MiniMax H3 into a world model that controls characters and cameras. The team says it used 8K samples while training 0.199% of the parameters.

World Labs says Atlas generates consistent worlds from text, images, and camera paths. Creator demos show sparse photos or phone-video captures reconstructed for reframing from new viewpoints.

SpAItial is recruiting creative partners for a beta that turns simple iPhone recordings into consistent multi-room 3D worlds. The company describes the system as a generative world model.
