On September 7, Nvidia CEO Jensen Huang took to X to praise OpenAI's new model, GPT-6 Astra, claiming it was trained on over 100,000 Nvidia Grace Blackwell NVLink72 systems. "From ChatGPT to o1, and then Astra — it only took four years. AGI (artificial general intelligence) has arrived. Congratulations to the OpenAI team."
