Marble

Marble is the consumer product from World Labs, the spatial-intelligence company co-founded by Fei-Fei Li. Where image and video models produce a picture of a place, Marble produces the place: a spatially consistent, persistent 3D world you can move through, edit, expand and export — the same geometry every time you re-enter it, rather than a fresh hallucination per frame.

Massively multimodal input. A text prompt, a single photo, several photos of the same space, or a video. You can also hand it structure directly: Chisel lets you block out a coarse 3D layout — rooms, volumes, where things go — and have Marble generate detail into that arrangement, which is the difference between describing a floor plan and drawing one.

Editing, expansion and composition. Worlds are editable after generation, from local tweaks to major restructuring. Expand fills a selected region with more world, so a room becomes a floor becomes a building. Compose joins separate worlds into a single extremely large space. Generated video output supports pixel-accurate camera control, so a shot can be re-run along the same path after an edit.

Exports that land in a real pipeline. Gaussian splats (SPZ and PLY) at the highest fidelity, triangle meshes in both low-poly collider and high-quality textured form, 360° panoramas, and rendered video. That set is aimed squarely at Unreal, Unity, Blender and Houdini users — a collider mesh plus a splat is a workable game-engine handoff, not a demo artefact.

Plans. Free gives 7,000 credits and up to four world generations but no export. Standard at $20/month raises that to 20,000 credits and twelve generations and unlocks splat, panorama and low-resolution collider-mesh export, community asset downloads, draft mode and credit top-ups. Pro at $35/month gives 40,000 credits, twenty-five generations, high-resolution textured mesh export, enhanced rendered video and commercial rights. Max at $95/month gives 120,000 credits and seventy-five generations. Note the shape of that: exporting anything at all is a paid feature, and commercial use starts at Pro.

Marble launched publicly in November 2025. In September 2026 World Labs announced Atlas, an omni world model generating 3D images and video at 1440p and up to a minute long, currently in early access with selected partners and slated to power future versions of Marble.
