Marble
Marble is World Labs’ generative 3D world-creation tool for making and sharing spatially coherent environments from images, video, text, or rough 3D layouts. The company describes it as its first product, powered by its generative 3D world models. Creation and exploration take place in the browser, with generated worlds intended for interactive editing, expansion, combination, and export into formats suited to creative and technical workflows.

What it does
Marble accepts several kinds of starting material: a text description, a single image, multiple images, video, a 360-degree panorama, or a coarse 3D layout. World Labs says the system uses these inputs to generate high-fidelity, persistent 3D worlds that maintain spatial coherence rather than producing only a flat image.
After generation, users can explore the environment interactively and modify it. The publisher documents editing at two levels: changing specific elements within a world or reshaping the broader environment. Users can also expand an existing space to build a larger setting, or combine generated spaces into a more extensive world.
Workflow
A typical workflow begins by supplying the visual reference, concept, footage, or layout that establishes the desired scene. Marble then generates an explorable 3D environment in the browser. From there, users can inspect the result, make targeted edits, adjust the overall world, and continue extending or combining spaces.
The finished world can be exported as a Gaussian splat, mesh, or video, according to World Labs’ product materials. These options support different downstream needs: interactive or immersive presentations, conventional 3D production, and video-based sharing or review. World Labs also provides access to Marble tutorials and API documentation through its official platform, although the supplied materials do not specify the full API feature set or implementation requirements.
Who it helps
Marble is positioned for creative production, virtual production, gaming, immersive media, architecture and design, and robotics simulation. A designer might use a reference image or rough layout to develop a navigable environment; a game or immersive-media team could expand and combine spaces into a larger setting; and a virtual-production workflow could use exported world data or video as part of scene development.
The tool is more specialized than a conventional AI image generator because its documented output is an explorable 3D world rather than a single still image. Its usefulness will depend on how well the generated geometry, spatial relationships, and editable elements fit a project’s requirements; the supplied sources do not provide independent quality benchmarks or detailed technical limitations.
Plans and limits
World Labs lists Free, Standard, Pro, and Max plans. The Free plan is listed at $0 per month with 7,000 credits and up to four world generations. Standard is listed at $20 per month with 20,000 credits and up to 12 generations; Pro at $35 with 40,000 credits and up to 25 generations; and Max at $95 with 120,000 credits and up to 75 generations.
The pricing page states that video input, splat and panorama exports, and other creation or export capabilities vary by plan. Commercial rights and high-resolution textured-mesh exports are listed for Pro and higher tiers, so users should check the current plan details before choosing Marble for commercial production.
