The next frontier of AI isn't just about understanding words—it's about comprehending the 3D world we live in
The Dawn of Spatial Intelligence
Imagine an AI that doesn't just read text or recognize images, but actually understands how objects exist and interact in three-dimensional space. This isn't science fiction—it's the emerging field of spatial intelligence, and it's poised to transform everything from filmmaking to robotics.
World Labs has introduced Marble, the first commercially available world model designed to give AI the ability to perceive, predict and interact with the physical world. Founded by AI pioneer Fei-Fei Li—the creator of ImageNet and often called the "Godmother of AI"—World Labs represents a fundamental shift in how we think about artificial intelligence.
What is Spatial Intelligence?
While large language models like ChatGPT excel at processing text, they fundamentally lack understanding of the physical world. Spatial intelligence is the scaffolding upon which human cognition is built, driving our reasoning, planning, and how we interact with our environment.
Think about how easily you navigate a room, predict where a ball will land, or imagine what the back of a building looks like from seeing only the front. These capabilities require spatial intelligence—the ability to understand geometry, motion, scale, and how objects relate to each other in three-dimensional space.
For AI systems, developing this capability has been elusive. Until now.
Enter Marble: The Game-Changing Platform
Marble is a state-of-the-art generative world model that creates 3D worlds from diverse input types, allows users to edit and expand them, and export them in various formats. Unlike previous attempts at world generation, Marble creates persistent, stable environments that don't morph or degrade as you explore them.
How Marble Works
The platform accepts multiple types of input:
- Text descriptions: Simply describe your vision and watch Marble generate a complete 3D environment
- Single or multiple images: Transform photographs into explorable 3D spaces
- Video clips: Upload short videos to provide rich spatial information
- 360° panoramas: Maximum control over world layout
- 3D structures: Use Marble's built-in editor to block out geometric layouts
Marble creates persistent, downloadable 3D environments rather than generating worlds on-the-fly as you explore, resulting in less morphing or inconsistency. This fundamental difference makes Marble suitable for professional applications where consistency matters.
The Chisel Editor: Separating Structure from Style
One of Marble's most innovative features is Chisel, an AI-native 3D editor that decouples spatial layout from visual appearance. Users can block out coarse spatial layouts using simple shapes, then add text prompts to guide the visual style—similar to how HTML provides website structure and CSS adds styling.
This approach allows architects to prototype buildings in minutes, game designers to rapidly create levels, and VR creators to define spaces without manual asset creation.
Real-World Applications Transforming Industries
1. Entertainment and Creative Media
Creative studios and VFX teams are using Marble to streamline 3D world production, transforming concept art into complete environments for films and games. What once required teams of 3D artists working for weeks can now be accomplished in minutes.
Film directors can visualize scenes before building physical sets. Game developers can prototype entire worlds to test gameplay mechanics. Virtual production teams can create immersive backgrounds for LED volume stages.
2. Robotics and Automation
Spatial intelligence is essential for robots to comprehend their physical environment, enabling them to navigate, manipulate objects, and interact with humans safely. Without understanding 3D space, even the most advanced AI robots remain fundamentally limited.
Researchers are using Marble's generative worlds to accelerate robot training, testing real-to-sim transfer scenarios. Instead of training robots in expensive physical environments, companies can generate unlimited virtual training scenarios.
3. Architecture and Urban Planning
Architects can transform rough sketches into detailed 3D walkthroughs for client presentations. Urban planners can visualize development projects in context. Interior designers can let clients explore spaces before construction begins.
4. Virtual and Augmented Reality
AR glasses, AI-powered headsets and wearable devices allow AI to interpret gestures, movement and environments more naturally through spatial awareness. Spatial intelligence is the foundation for the next generation of immersive computing.
5. Scientific Research and Simulation
Spatially intelligent systems can simulate experiments, test hypotheses in parallel, and explore environments inaccessible to humans—from deep oceans to distant planets. This technology transforms computational modeling in fields like climate science and materials research.
The Technology Behind the Magic
Marble uses Gaussian splats for rendering, a technique that enables high-fidelity, real-time 3D representation. This architecture permits precise camera control, interactive scene editing, and runs across diverse platforms from phones to VR headsets.
Generation times are remarkably fast—approximately 30 seconds to create a panoramic world from text, image, or 3D structure. Users can then expand these worlds by telling the model to generate more detail in specific regions, or combine multiple worlds using "composer mode."

They excel at rapid prototyping, exploration, and generating base environments, but professional projects still benefit from human artistic direction, refinement, and creative decision-making.
What's the difference between "world models" and large language models?
Large language models (LLMs) understand and generate text based on patterns in language. World models understand and generate three-dimensional spaces, including geometry, physics, and spatial relationships. While LLMs work with sequential, symbolic data, world models work with spatial, continuous data representing the physical world.
Can Marble generate animated or moving scenes?
Currently, Marble generates static 3D environments that you can navigate. While you can render camera movements through these worlds as videos, the objects within the worlds don't have animation. Dynamic scene generation is an active area of research in spatial intelligence.
How accurate are the 3D reconstructions from photos?
Accuracy depends on input quality and complexity. Single images require the AI to infer unseen areas, which may not match reality perfectly. Multiple images or 360° panoramas provide more information and result in more accurate reconstructions. For critical accuracy needs, traditional photogrammetry methods may still be preferable.
