Cosmos is infrastructure for physical AI, not a Marble alternative.
NVIDIA launched Cosmos as a world foundation model platform for physical AI: synthetic data, simulation, robotics, vehicles, and embodied reasoning. Cosmos 3 arrived as a March 2026 preview direction across generation, reasoning, and action simulation.
The public GitHub organization is the inspectable surface: Predict, Transfer, Reason, Curate, Evaluator, RL, Cookbook, and related repos. That is a platform catalog, not a single consumer demo.
Cosmos dossierPhysical-AI world foundation model platform.
The word world here means a trainable environment, not a shareable scene.
A Cosmos workflow can matter enormously to a robotics team and still be the wrong click for a game artist. This site keeps NVIDIA in the adjacent-progress lane so that physical-AI progress does not get sold as an explorable 3D product.
Hardware, SDK, and enterprise context still matter. Preview and available components should be named from current NVIDIA posts and the GitHub stack, not flattened into one ship date.
How to verify
Use NVIDIA Newsroom plus the Cosmos GitHub org.
Launch posts, Cosmos 3 coverage, the Physical AI Data Factory Blueprint, and the GitHub organization are the primary sources. NVIDIA's world-models glossary is useful framing, not a product spec.
If the reader wanted Gaussian splat export or a 360 skybox, send them back to Marble or Skybox AI.
