Marble (World Labs)

World Labs' world-generation product that turns text, images, or video into a persistent, exportable 3D scene.

Marble is the generative world model product that World Labs, co-founded by Fei-Fei Li, formally launched on November 12, 2025. A user provides text, one or more images, or video, or first blocks out a rough 3D layout with the companion tool Chisel, and Marble generates a persistent 3D scene that can be freely walked through and viewed, exportable as a Gaussian splat (representing the scene with a large number of semi-transparent ellipsoids), a triangle mesh (including a simplified mesh for collision), or a video rendered along a specified camera path. Unlike a video world model that generates frames one at a time, it outputs explicit 3D assets that can be dropped into a game engine or simulator. In July 2026, World Labs demonstrated using generated scenes for real-to-sim-to-real robot training; in September, its underlying model, Atlas, was released and will power later versions of Marble; on September 28, AMD announced it would acquire World Labs, with the deal expected to close before the end of 2026.

ExampleUpload a photo of a living room, and Marble generates a 3D living room you can look around in; export the collision mesh and drop it into a simulator to let a robot practice navigating inside it.
