❯ Jensen Huang confirms Astra trained on over 100,000 Grace Blackwell chips, with 400,000 more coming

the specPer Jensen Huang’s public remarks, GPT-6 Astra was trained on more than 100,000 Nvidia Grace Blackwell NVLink72 systems, and he says another 400,000 come online soon. OpenAI had previously given only a vague figure — “over 100,000 GPUs at the Stargate site in Texas” — making this the first time both the part number and the size of the next batch have been stated together.

three framingsHuang added something heavier: AGI has arrived. For contrast, OpenAI president Greg Brockman hedged on September 5 — “we’re now moving into the AGI era, whether you view it as this model, the last one, or the next one” — while Wharton’s Ethan Mollick pushed back that this is at most “jagged AGI”, and that beating human experts at most tasks is the bar, which has not been cleared. OpenAI’s own disclosure was a single number about the Stargate site, and 3 people have now given 3 framings.

what the scale meansA chip supplier vouching for a customer’s training scale is itself unusual. The ramp from 100,000 to 400,000 says the compute bar for the next model generation is beyond anything a new entrant can assemble; it also writes Nvidia into the narrative, as both the seller of the cards and the party with the most reason to declare that AGI has arrived. That last part is exactly what needs discounting.

▪ SIGNALThe man selling the cards announced AGI has arrived — discount the claim by the speaker’s position.
