Marble is the world’s first generative model that outputs fully navigable 3‑D worlds in real time

The product was built over a year by a team of ~30 researchers and engineers, leveraging cutting‑edge frontier models.
Marble can synthesize geometry, textures, and physics from a single textual or image prompt, producing an interactive scene within seconds.
It runs on a single H100 GPU for real‑time demo, showcasing the efficiency of the underlying architecture.
Users can explore the world via a web interface, walk around, and even export meshes for downstream pipelines.
This claim positions Marble as a pioneering commercial deployment of world‑model technology.
