World Labs, the AI startup founded by computer scientist Fei-Fei Li, has raised **$1 billion** in a fresh funding round to advance "spatial intelligence," AI that can understand and operate in the 3D world. Investors named across reports include Autodesk, Nvidia, AMD, Andreessen Horowitz, Emerson Collective, Fidelity Management & Research Company, and Sea. Autodesk invested **$200 million** and will serve as an adviser. The funding arrives as AI investment becomes more selective, with interest shifting toward "world models" that can navigate and make decisions in three-dimensional space. World Labs' spatial intelligence refers to AI that can reason about 3D reality rather than relying mainly on 2D inputs. Late last year, the startup launched its first product, Marble, a model that can generate 3D worlds from image or text prompts. With the new funding, World Labs is focused on improving applications for areas including robotics and scientific discovery. World Labs did not disclose a valuation, but sources say the startup was in funding discussions at a valuation of about **$5 billion**.
