Fei-Fei Li's World Labs Raises 1 Billion USD for 3D AI Push

World Labs, the artificial intelligence startup founded by Fei-Fei Li, has raised $1 billion funding in a major investment round to scale technology focused on spatial intelligence, according to Reuters.

The funding marks one of the largest investments to date in AI startups developing systems designed to understand and operate in three-dimensional environments.

The round drew participation from several strategic and financial investors, including AMD, Nvidia, Autodesk, Emerson Collective, Fidelity Management & Research Company, and Sea.

Autodesk committed $200 million to the round and will also act as a strategic adviser, underlining strong industry interest in 3D AI technology.

• Fei-Fei Li’s World Labs secures $1 billion to advance 3D AI systems
• World Labs funding signals strong investor push toward spatial intelligence
• Nvidia, AMD and Autodesk back World Labs’ 3D world-model technology

World Labs is developing world models that enable machines to perceive, reason about, and generate three-dimensional environments. Unlike traditional systems focused on text or flat images, spatial intelligence models are built to interpret physical space in a structured manner. These capabilities are expected to support applications across robotics, simulation, augmented reality, and virtual reality.

One of the company’s core technologies, the Marble model, is designed to generate coherent 3D worlds from a single image, video clip, or text prompt. The system focuses on maintaining spatial consistency, allowing environments and objects to behave predictably across viewpoints and interactions, a requirement for AI research involving real-world simulation.

Li is widely regarded as a leading figure in modern artificial intelligence and is best known for her work on ImageNet, a dataset that accelerated progress in computer vision. She launched World Labs in 2024 after raising $230 million. While the company has not disclosed its current valuation, media reports have previously indicated discussions around a $5 billion valuation.

The latest funding comes as competition intensifies among firms pursuing 3D world modelling as a foundation for more capable robots and interactive systems. World Labs’ raise reflects continued investor confidence in artificial intelligence infrastructure grounded in physical space rather than text-only systems.
