Marble is World Labs' first commercial product: a world model that turns text, images, video, 3D layouts and panoramas into persistent, downloadable 3D worlds, with the Chisel editor for modifications, expansion and composer modes, and exports to Gaussian splats, meshes and video. Pricing is freemium — Free (4 generations), Standard $20/month (12), Pro $35/month (25), Max $95/month (75) — with commercial rights starting at the Pro tier.

That spatial intelligence — models that understand 3D space, not just words and pixels — is AI's next platform, and Marble's editable, downloadable worlds are the wedge.

$230M raised out of stealth in September 2024, then a $1B round announced February 2026 with $200M from Autodesk and participation from AMD, Nvidia, Emerson and Fidelity — over $1.2B total.

Founded in 2024 by Fei-Fei Li (Stanford professor and former Google Cloud AI chief), Justin Johnson and Ben Mildenhall, World Labs came out of stealth in September 2024 with $230M and a December 2024 demo that turned a single image into a navigable 3D world, which went viral.

On November 12, 2025 World Labs shipped Marble to general availability: multimodal inputs (text, image, video, 3D layout, panorama), persistent downloadable worlds, the Chisel 3D editor, expansion and composer modes, and exports to Gaussian splats, meshes and video — with freemium pricing from free to $95/month and commercial rights from Pro up. TechCrunch and The Verge covered the launch the same day; competitors Decart, Odyssey and Genie were still demos or previews. In February 2026 World Labs raised $1B, with Autodesk investing $200M to bring world models into 3D design workflows.

The bet is scaling fast: Marble is a paid product with four tiers, and on September 1, 2026 the company announced Atlas, its next-generation omni world model — up to one minute of 1440p camera-controlled video, spatial reconstruction, and early access with partners — saying it will power future versions of Marble. With over $1.2B raised and reports suggesting a $5B valuation target, World Labs is the best-capitalized pure world-model company, though rivals are shipping their own releases.

World Labs bet that spatial intelligence — understanding 3D space, not just language and pixels — is the next platform after text and image models, and that a world model company could own it.

It chose a commercial wedge over a demo: Marble launched with real pricing, downloadable worlds, an editor and exports, so gaming, VFX and design teams could actually ship with it.

The funding validates the platform bet: Autodesk, AMD and Nvidia put $1B behind world models in February 2026, a year after rivals were still showing previews.

Atlas shows the roadmap is still active: a next-gen omni world model announced September 2026 will power Marble, keeping the product and the research bet on the same track.

Ship the wedge before the demo fades: World Labs turned a viral preview into a paid, downloadable, editable product within a year, while rivals stayed in demos — timing made the bet a business.

As of September 2, 2026 World Labs is live and scaling: Marble is a paid product with four tiers, Atlas was announced September 1, 2026 in early access with partners, and the company has raised over $1.2B — including $200M from Autodesk, plus AMD, Nvidia, Emerson and Fidelity — with reports suggesting a $5B valuation target. The open question is whether Marble converts attention into durable revenue before rivals; the launch HN threads (48 and 64 points) show interest, not scale. World Labs went from stealth to its first paid product in 14 months — a fast path for a model bet.
