Marble
What it is
Marble is the first product from World Labs, the spatial intelligence company founded by Fei-Fei Li, Justin Johnson, Christoph Lassner and Ben Mildenhall. It generates spatially consistent 3D worlds from text, single or multiple images, video clips, 360 panoramas or coarse 3D layouts. Once a world exists, users can edit specific elements, expand it outward or combine several worlds into a larger scene. Finished worlds can be exported as Gaussian splats, meshes or videos for use in game engines, VFX pipelines, design reviews and robotics simulation. Marble runs in the browser on a credit system, with a free tier for a few generations each month and paid plans that add more inputs and modes.
Key features
- Text, image, video and panorama inputs
- 3D layout control for scene structure
- Interactive editing and world expansion
- Export as splats, meshes or video
What we liked
- + Produces persistent 3D spaces, not just clips
- + Wide choice of input types
- + Exports fit existing 3D pipelines
Worth noting
- · Free tier allows only a few worlds a month
- · Advanced modes require higher paid plans
Editor's notes
More context from AI BirdView
Most generative tools stop at a flat image or a short video, but Marble produces a 3D place you can actually move through and keep working on. It comes from World Labs, a research-led company whose founders are well known in computer vision and graphics, and that pedigree shows in how much control the app gives over structure and layout. World Labs announced in September 2026 that it is joining AMD, so it is worth watching how the product evolves.
- Accepts text, photos, multiple images, video and 360 panoramas as starting points
- Layout-based generation lets you block out a scene before the model fills in detail
- Worlds can be edited piece by piece, expanded outward or merged with other worlds
- Exports as Gaussian splats, meshes or video, so results move into engines and editors
- Marble Labs offers tutorials, case studies and community examples for getting started
Marble is best for game designers, VFX artists, architects and robotics teams who need quick, explorable 3D environments for previs, prototyping or simulation. A practical tip: start with a single strong reference image on the free tier to learn how the model interprets space, then move to layout-based generation once you need precise control over where things sit.
