OpenAI released GPT‑6 Astra, built with its largest-ever training run using over 100,000 GPUs at the Stargate site in Texas.
OpenAI unveiled GPT‑6 Astra on Thursday, describing it as a “generational leap” that pushes the company into what president Greg Brockman called the “AGI era.” According to the firm, Astra was trained in its largest‑ever run, harnessing more than 100,000 GPUs at the new Stargate super‑computing site in Texas. The model also marks OpenAI’s first use of other AI systems to supervise the training process, a step the company says improves both scale and reliability.
Astra is initially being rolled out through the Daybreak Access program, which limits early use to select organisations. Early benchmarks cited by OpenAI show the model completing tasks on the Mind2Web suite 1.9 times faster than the previous Sol‑based setup, and it is engineered to run larger, more capable autonomous agents. The announcement follows OpenAI’s earlier launch of Astra, reported on 3 September, and builds on the company’s rapid expansion of high‑performance hardware.
The significance lies in the sheer compute investment and the shift toward model‑in‑the‑loop training, both of which signal OpenAI’s ambition to close the gap to artificial general intelligence. At the same time, the scale has already prompted safety concerns: CEO Sam Altman disclosed that the Astra run was frozen for two weeks after internal metrics flagged a “Critical” danger level, the first such pause for the firm’s flagship development.
Going forward, observers will watch how OpenAI balances the promised performance gains with robust oversight as Astra moves beyond the limited Daybreak cohort. Regulatory scrutiny, competitive responses from other AI firms, and the rollout of Astra‑powered agents to broader markets will shape whether the model lives up to its AGI‑era branding or encounters new safety and governance hurdles.
