NVIDIA previews Cosmos 3 as a unifying physical-AI world model

What changed

GTC materials linked Cosmos 3 to a physical-AI data-factory blueprint.

Context summary

Cosmos 3 to unify world generation, physical-AI reasoning, and simulation.

Why visitors should care

This remains a meaningful primary-source product update rather than a vague platform claim. The March 16, 2026 press materials established Cosmos 3 and the physical-AI data-factory blueprint together, and NVIDIA's still-active public GitHub surface makes the stack easier to verify as an ecosystem of world generation, curation, evaluation, and robot-training tools rather than a single demo video.
