Marble, World Labs' world-model product, generates editable, persistent 3D worlds from text, images, video, or 3D layouts.
Marble, the first product from World Labs, turns text prompts, images, videos, panoramas, or coarse 3D layouts into high-fidelity, persistent 3D worlds that users can move through, edit, expand, and share in VR. Generation runs on selectable world models, currently Marble 1.1 and Marble 1.1 Plus, with pano editing, variations, and the Chisel 3D layout editor. Outputs export to Unity, Unreal, Blender, and Houdini, plus meshes, splats, and shareable web and VR links.
Marble is sold as a credit-based subscription with Free, Standard, Pro, and Max tiers plus custom enterprise plans, while a separately billed World API exposes the same world-generation models to developers. World Labs says the Atlas omni world model will power future versions of Marble. The product runs in desktop and mobile web browsers at marble.worldlabs.ai, which hosts the community gallery.
