Marble

Marble is World Labs’ platform for generating high-fidelity, persistent 3D environments. Users can start with a text prompt, one or more images, video, panoramas, or rough 3D structures and turn those inputs into explorable worlds. Marble also provides editing and studio tools for combining environments, changing scenes, creating cinematic camera movements, and preparing worlds for sharing or downstream use. The platform is designed around spatial intelligence rather than conventional 2D image generation, producing environments that users can move through and continue editing. Generated worlds can also be exported for use in other workflows. This makes Marble relevant to game development, virtual production, visualization, immersive experiences, and creators experimenting with AI-generated 3D environments.
