Fei-Fei Li on World Labs' Marble: the first public 3D world generation model and the spatial intelligence frontier

Fei-Fei Li's World Labs has released what it claims is the world's first publicly available 3D world generation model, branded Marble. The model goes beyond static generation, allowing users to interact with, create, and edit 3D environments in real time, positioning it as a foundational tool for spatial intelligence applications.

World Labs has raised more than $240 million in publicly disclosed funding. Li describes the company as still capital constrained, signaling further fundraising is likely. Her framing of being 'just getting started' suggests the Marble release is an early commercial anchor rather than a mature product.

“One of the things we just have done is really putting out the world's first 3D world generation model that is available to everybody. And not only is it generative, it allows users to interact and create and edit... We've raised more than $240,000,000 publicly. We are capital constrained. I'm just getting started.”
