Brockman says Astra trained on more than 100,000 GPUs

OpenAI president Greg Brockman gave a specific compute figure for Astra in an interview with Stratechery. Astra trained on more than 100,000 GPUs, he said, its first run at that scale. He called it OpenAI's most aligned model yet.

Brockman argues computer use marks the break from what he termed the connector era. A model that can drive software with no API doesn't need a company to build an integration first, since it just needs a screen. For builders, that means an agent can act on whatever it can reach, without a human confirming each step.

Pressed on why security hardening lagged before a Hugging Face incident forced the issue, Brockman didn't dodge it. He conceded the field's default reflex is to restrict access massively rather than defend it properly. That default still holds now. Safety trails capability as the norm, not the exception.

Brockman gave no timeline for proactive defense becoming the default, and he didn't say whether the 100,000-GPU figure is a peak or a sustained count. Read it as an order of magnitude.
