Dr. Fei-Fei Li cites the deduction of DNA's double-helix structure as a prime example of a cognitive leap that required deep spatial and geometric reasoning—a feat impossible with language alone. This illustrates that future AI systems will need world-modeling capabilities to achieve similar breakthroughs and augment human scientific discovery.

While LLMs dominate headlines, Dr. Fei-Fei Li argues that "spatial intelligence"—the ability to understand and interact with the 3D world—is the critical, underappreciated next step for AI. This capability is the linchpin for unlocking meaningful advances in robotics, design, and manufacturing.
Language is just one 'keyhole' into intelligence. True artificial general intelligence (AGI) requires 'world modeling'—a spatial intelligence that understands geometry, physics, and actions. This capability to represent and interact with the state of the world is the next critical phase of AI development beyond current language models.
Large language models are insufficient for tasks requiring real-world interaction and spatial understanding, like robotics or disaster response. World models provide this missing piece by generating interactive, reason-able 3D environments. They represent a foundational shift from language-based AI to a more holistic, spatially intelligent AI.
Drawing a parallel to the Cambrian Explosion, where vision evolved alongside nervous systems, Dr. Li argues that perception's primary purpose is to enable action and interaction. This principle suggests that for AI to advance, particularly in robotics, computer vision must be developed as the foundation for embodied intelligence, not just for classification.
World Labs argues that AI focused on language misses the fundamental "spatial intelligence" humans use to interact with the 3D world. This capability, which evolved over hundreds of millions of years, is crucial for true understanding and cannot be fully captured by 1D text, a lossy representation of physical reality.
World Labs co-founder Fei-Fei Li posits that spatial intelligence—the ability to reason and interact in 3D space—is a distinct and complementary form of intelligence to language. This capability is essential for tasks like robotic manipulation and scientific discovery that cannot be reduced to linguistic descriptions.
AI is developing spatial reasoning that approaches human levels. This will enable it to solve novel physics problems, leading to breakthroughs that create entirely new classes of technology, much like discoveries in the 1940s led to GPS and cell phones.
Current multimodal models shoehorn visual data into a 1D text-based sequence. True spatial intelligence is different. It requires a native 3D/4D representation to understand a world governed by physics, not just human-generated language. This is a foundational architectural shift, not an extension of LLMs.
Dr. Fei-Fei Li realized AI was stagnating not from flawed algorithms, but a missed scientific hypothesis. The breakthrough insight behind ImageNet was that creating a massive, high-quality dataset was the fundamental problem to solve, shifting the paradigm from being model-centric to data-centric.
Human intelligence is multifaceted. While LLMs excel at linguistic intelligence, they lack spatial intelligence—the ability to understand, reason, and interact within a 3D world. This capability, crucial for tasks from robotics to scientific discovery, is the focus for the next wave of AI models.
