NVIDIA Cosmos 3, an open omnimodal world model released under the OpenMDW-1.1 license, is used with Amazon SageMaker HyperPod to build a Physical AI model factory that runs a continuous pipeline of synthetic data generation, model post-training, and closed-loop simulation on a single persistent GPU cluster, leveraging the model's Mixture-of-Transformers architecture with per-layer joint attention.
