Jensen Huang Declares 'AGI Has Arrived' on X, Credits OpenAI GPT-6 Astra Trained on 100K Grace Blackwell Systems

Nvidia CEO Jensen Huang posted on X on Sept. 6: 'From ChatGPT to o1 to Astra in 4 years. AGI has arrived. Congratulations @OpenAI team. 400K GPUs coming online next.' Huang credited OpenAI's GPT-6 Astra as the milestone and noted the model was trained on more than 100,000 Nvidia Grace Blackwell NVLink72 systems. The declaration lands three days after OpenAI's Astra debut and hardens the 'AGI era' framing pushed by OpenAI President Greg Brockman.
