Marble (World Labs)

World Labs’ Marble is a spatial intelligence model designed to generate and manipulate persistent 3D interactive worlds from 2D inputs.

Founded by AI pioneer Fei-Fei Li, World Labs is building Marble to move beyond flat pixel generation into the realm of spatial intelligence. The system uses Large World Models (LWMs) to create 3D environments that respect physical laws, allowing users to navigate and edit scenes with consistent geometry. By treating the world as a structured 3D space rather than a sequence of frames, Marble provides a foundational tool for developers in gaming, robotics, and professional design. The company secured $230 million in funding from investors like Andreessen Horowitz and Radical Ventures to scale these models for real-world application.
