NVIDIA has released its Isaac GR00T open models for physical AI, enabling robots to understand natural language instructions and execute complex, multi-step tasks using vision-language-action reasoning. Released during National Robotics Week, the models represent a pivot from AI as a software phenomenon to AI as a physical one — machines that see, reason, and act in unstructured environments.
