World Labs, the startup founded by AI pioneer Fei-Fei Li, has released its generative world model, Marble, publicly available after a two-month beta with early users. 

“Marble can create 3D worlds from text, images, video, or coarse 3D layouts,” World Labs said. “Users can interactively edit or expand worlds.”

The company raised $230 million last year in September. 

Alongside the launch, World Labs introduced Marble Labs, a workspace for creators to explore workflows, case studies, and documentation. “It is where artists, engineers, and designers push the boundaries of world models,” the company said.

There are many other startups like Decart and Odyssey building world models and putting out free demos, and Google’s Genie is still only in a research preview.

Marble supports text-to-world and image-to-world generation, as well as multi-image and video inputs for greater control over scene structure. Worlds can be exported as Gaussian splats, triangle meshes, collider meshes, or videos with pixel-level camera control.

Marble now includes AI-native world editing tools, enabling object removal, style changes, and structural modifications. World Labs also unveiled Chisel, an experimental 3D sculpting mode that lets users design coarse layouts and apply styles through prompts. “Chisel decouples structure from style,” according to the company.

Users can expand worlds through one-step enlargement or compose multiple worlds to build large spaces. Enhanced video export can add detail, motion, and cleanup while preserving spatial structure.

World Labs said Marble is an early step toward broader spatial intelligence. “Future world models will let humans and agents alike interact with generated worlds in new ways,” the company said.
