  "account": "Building a Physical AI system requires a continuous pipeline that generates synthetic data, trains perception and policy models, and evaluates them in closed-loop simulation. This continuous process is facilitated by a Physical AI model factory. One way to implement such a factory is by using NVIDIA Cosmos 3 on Amazon SageMaker HyperPod. Cosmos 3 is a Mixture-of-Transformers (MoT) design with per-layer joint attention and a deliberate train-versus-inference asymmetry. The architecture integrates video, image, action, and sound into a single token stream, treating them all as a unified sequence. This integration enables Cosmos 3 to function both as a video generator for synthetic data and as an action policy for deployment. The model utilizes a single transformer trunk to manage both generation and evaluation tasks.",
  "summary": "Building a Physical AI system takes a continuous pipeline, not a single training job. This post shows how to run that model factory (synthetic data generation, post-training, and closed-loop evaluation with NVIDIA Cosmos 3) on a persistent, resilient Amazon SageMaker HyperPod cluster on Amazon EKS, with GPU goodput as the metric that matters.",
