What is Nvidia's Cosmos model and how does it represent a breakthrough in robotics technology?

Nvidia's Cosmos is a World foundation model specifically designed to help robots understand and interact with the physical world. The model comes in three tiers - nano, super, and Ultra - all of which are openly licensed and available on GitHub for developers and researchers. This technology represents what Nvidia calls a "ChatGPT moment for robots," meaning it could be as transformative for robotics as ChatGPT was for conversational AI. The Cosmos model aims to bridge the gap between artificial intelligence and real-world physical interaction, potentially revolutionizing how robots navigate and respond to their environments. The announcement was part of Nvidia's broader showcase of cutting-edge AI infrastructure, including their powerful NV72AI racks that contain 130 trillion transistors and draw 120,000 watts of power, demonstrating the massive computational resources behind these robotic advancements.
