Fei-Fei Li's World Labs closed a $1 billion funding round this week, pulling in two of the biggest names in AI chips alongside a design-software company betting on where 3D content creation is headed. The startup said Wednesday that Nvidia and AMD invested, along with Autodesk, Emerson Collective, Fidelity Management & Research Company and Sea. It did not disclose a new valuation.
Autodesk's check stood out for its size and its terms. The design-software maker put in $200 million and will also serve as an adviser to World Labs, a pairing that goes beyond writing a check. Autodesk builds the tools architects, engineers and animators use to model physical objects and spaces, which makes it a natural partner for a company trying to teach AI systems to reason about three-dimensional environments rather than flat images or text.
That capability is what World Labs calls spatial intelligence, and it underpins Marble, the company's model for generating 3D worlds from image or text prompts. World Labs has said its broader family of foundational models can perceive, generate and interact with 3D environments, a step beyond the still-image and video generators that have dominated AI product launches over the past two years. Li has said the technology could eventually support augmented and virtual reality applications or robotics, though none of those markets have yet produced a large-scale commercial deployment of the technology.
The new round follows $230 million Li raised in September 2024 to launch the company, a jump in scale that reflects how much capital investors are now willing to commit to unproven categories of AI research. Bloomberg reported in January that World Labs was in funding talks at a valuation of roughly $5 billion, as Reuters notes; the company's decision not to confirm a figure this time leaves outside observers guessing at how much the new backing moved that number.
World Labs is not alone in chasing world models, AI systems designed to simulate and predict how physical environments behave. Google DeepMind's Genie family already generates and simulates 3D environments, and Yann LeCun, Meta's former chief AI scientist, left the company to start AMI Labs with the same technical bet. The scramble among well-funded labs to stake out spatial intelligence before it has an obvious product suggests investors see the category as the next frontier once text and image generation mature, even if none of them can yet point to a workflow it has replaced.
What's missing so far from the coverage of this round is any indication of revenue, customer commitments or a shipping product beyond Marble's early demonstrations. A $1 billion raise buys a research organization time and compute, not proof that spatial intelligence models are ready for the enterprise workloads their backers eventually want them to run.
