What is NVIDIA Cosmos3?

On June 1, 2026, NVIDIA launched Cosmos3 — the world first fully open-source, multi-modal physical AI large model. The model represents a disruptive breakthrough in physical AI, capable of visual reasoning, world generation, and action prediction .

Key Capabilities

  • Visual Reasoning: Understand and interpret visual information in physical contexts
  • World Generation: Generate realistic physical environments and scenarios
  • Action Prediction: Forecast outcomes of physical actions in real-world settings
  • Cross-Modal Generation: Naturally understand and generate content across different modalities

Technical Foundation

Cosmos3 is trained on a vast physical AI dataset, enabling industry-leading simulation accuracy. The model can naturally understand physical laws, spatial relationships, and cause-effect dynamics — capabilities essential for robotics, autonomous systems, and industrial automation .

Cosmic Alliance

NVIDIA has joined forces with multiple industry-leading teams to establish the "Cosmic Alliance" — a coalition driving the transformation and development of physical AI. The alliance aims to accelerate adoption of physical AI across industries .

Why Physical AI Matters

As AI moves from chat interfaces to real-world applications, physical intelligence becomes critical. Cosmos3 addresses the gap between language models (which manipulate text) and embodied AI systems (which must understand physics, spatial relationships, and action outcomes).
