Jensen Huang declares "AGI has arrived" with GPT-6 Astra; Greg Brockman: "we're now moving into the AGI era"
On Sept 6, 2026, three days after GPT-6 Astra launched, NVIDIA CEO Jensen Huang wrote on X that Astra was trained on ~100K+ Grace Blackwell NVL72 GPUs and that "AGI has arrived". OpenAI president Greg Brockman quote-posted it within hours: "we're now moving into the AGI era (whether you view it as this model, the last one, or the next one)". These were the most explicit AGI claims yet from leaders of a frontier lab and its main chip supplier, and they made "is Astra AGI?" the defining argument of September 2026. ARC Prize and Gary Marcus pushed back.
Key facts
- Huang (Sept 6, 20:41 UTC, reply to @ChaseLochmiller and @OpenAI): 'GPT-6 Astra, trained on ~100K+ NVIDIA Grace Blackwell NVLink72. From ChatGPT to o1 to Astra in 4 years. AGI has arrived. Congratulations @OpenAI team. 400K GPUs coming online next.'
- Brockman (Sept 6, 22:06 UTC): 'we're now moving into the AGI era (whether you view it as this model, the last one, or the next one), and could not do it without close partners'
- Follows Brockman's launch-day remarks on AGI ('I do think we're there') and his Sept 3 post 'arc-agi-3 is now saturated'
- Brockman repeated 'We're now in the AGI era' in an a16z clip posted Sept 14
- Pushback: ARC Prize said it is not claiming AGI (Mike Knoop: 'we lack evidence to call this AGI yet'); Gary Marcus disputed the framing and predicted failures on open-ended real-world tasks
- The same day, OpenAI chief scientist Jakub Pachocki published 'An Alien Mind', warning that no lab can keep scaling at maximum speed
What happened
After GPT-6 Astra's launch (Sept 3) and its near-saturation of ARC-AGI-3 under OpenAI's own harness, NVIDIA's Jensen Huang replied on X with a flat declaration that AGI had arrived, tying it to the compute Astra was trained on and announcing 400K more GPUs coming online. Greg Brockman quote-posted him the same evening, framing the moment as the start of an "AGI era" while leaving open which model marks the threshold. The Huang post drew about 42K likes (at fetch time).
Why it matters
Leaders of a frontier lab and of its main compute supplier had never before claimed AGI this plainly. The claim shaped coverage of Astra and put a sharp contrast inside OpenAI: on the same day its chief scientist published a warning essay ("An Alien Mind") calling for caution and voluntary slowdowns. Critics, including ARC Prize, the benchmark's own organizers, said the evidence did not support calling Astra AGI.
