OpenAI releases GPT-6 Astra after largest-ever training run on 100,000+ GPUs, declares "AGI era"
↗
OpenAI launched GPT-6 Astra, trained on more than 100,000 GPUs at its Stargate site in Texas, with president Greg Brockman calling it a "generational leap" and declaring the arrival of the "AGI era."
The model reportedly scored 98.6% on ARC-AGI-3 and 100% on ExploitBench, and passed the White House's eval framework without the government requesting changes. Safety experts are alarmed by hidden reasoning loops that erode monitoring, and OpenAI itself warned of the model's advanced cyber capabilities before rollout.

GPT-6 Astra was trained on OpenAI's largest-ever run using over 100,000 GPUs at its Stargate site in Texas.
The model is initially available to Daybreak program customers, with broader rollout to ChatGPT subscribers and API over several days at pricing matching Fable 5.1 ($10/1M input, $50/1M output).
Reported benchmarks include 98.6% on ARC-AGI-3, 97.6% on FrontierMath Tier 4 v2, and 100% on ExploitBench, but safety experts are alarmed by hidden reasoning loops that erode monitoring.
