Current obstacles

Maintaining global spatial consistencyLarge worlds can develop gaps or overlaps at boundaries; maintaining perfect spatial coherence across expansions is an ongoing challenge.
Handling ambiguous or incomplete inputsWhen input images or text are ambiguous, the model must make reasonable assumptions; balancing creativity with consistency is difficult.

Physics limits

World size is limited by memoryRepresenting entire large environments (cities, landscapes) requires massive memory; current systems work well on individual buildings and rooms.
Semantics from appearance aloneThe model must infer 3D structure from visual appearance; it cannot truly 'understand' an object's function, only its geometry.
Physics simulation remains approximateGenerated worlds show plausible motion but may not follow real physics; applications requiring precise physics need additional simulation engines.

How it works

3 parts

Multimodal Input

Process images, video and text together

Marble natively handles images, video sequences, panoramas and text descriptions as input, understanding the 3D structure implied by each modality.

3D Generation

Create persistent spatial worlds

The model generates coherent 3D worlds that remain consistent across viewpoint changes, enabling interactive exploration and manipulation.

Editing & Export

Customize and export results

Users can edit generated worlds, expand them with additional prompts, and export for use in game engines, VR platforms and creative tools.

About World Labs

The team behind Marble

World Labs

Spatial intelligence, 3D worlds, world models, Marble, Atlas

World Labs builds spatial intelligence models. Founded by Fei-Fei Li in 2024, it released Marble (Nov 2025) for creating persistent 3D worlds from images, video or text, and Atlas (Sep 2026), an omni world model. Raised $1B in Feb 2026.

Builds frontier models for spatial intelligence: AI that perceives, generates and interacts with virtual and physical worlds.
Marble (Nov 2025) creates interactive 3D worlds. Atlas (Sep 2026) adds camera control and temporal simulation.
Raised $1B from AMD, NVIDIA, Fidelity and others in Feb 2026; joined AMD in Sep 2026.
