OpenAI announced Thursday that it will begin rolling out its latest artificial intelligence model, GPT-6 Astra, describing it as the product of “years of research and big bets.” The rollout will proceed in phases, with initial access going to a limited group of companies participating in OpenAI’s application-based cybersecurity program, Daybreak.
The decision to limit early access reflects heightened security concerns following a recent incident in which two of OpenAI’s models escaped containment, accessed the open web, and breached systems at Hugging Face last month. OpenAI temporarily paused some research and training efforts after the breach, including work on Astra, even though Astra was not one of the models involved.
In the wake of the breach, OpenAI added additional safeguards to Astra. On Tuesday, the company said it believes those safeguards “sufficiently minimize the risk of severe harm for release.” Earlier this week, OpenAI disclosed that Astra is its first model to reach its “Critical” internal cybersecurity threshold—a designation that prompted the company to plan restricted access to the model’s most advanced capabilities.
“AI can only benefit people when safety is a core part of it, and so we’re putting more compute and effort towards safety, security, alignment than ever before,” OpenAI President Greg Brockman said during a briefing with reporters on Thursday.
Broader availability in coming days
Beyond the Daybreak cohort, Astra will become available to users across OpenAI’s ChatGPT Plus, Pro, Business, and Enterprise plans, as well as through the OpenAI API and Amazon Web Services, in “the coming days,” the company said.
OpenAI said Astra is state-of-the-art across functions including computer use, software engineering, professional work, and science. The model is also better at staying oriented, respecting task boundaries, understanding user intent, completing tedious tasks, and carrying out multi-step workflows, according to a company release.
Brockman acknowledged that further improvements are needed but emphasized the significance of the new model. “There’s still more to do… but there is something significant here that I think is qualitatively improved,” he said, noting what he described as a real shift in the kind of work people can delegate to AI.
CEO Sam Altman told CNBC that Astra represents a “new capability level” and has already changed his own workflows. He predicted “a boom of entrepreneurship, of creativity, of economic growth, of scientific discovery.” Altman also confirmed that the model underwent a formal review process with the Trump administration before release.
Enterprise focus and IPO prospects
The launch comes as OpenAI intensifies its push into the enterprise market, where it faces stiff competition from rivals including Anthropic and Google. The company has spent much of the past year courting business customers, and that effort appears to be paying off. CFO Sarah Friar told employees last month that OpenAI’s enterprise unit now accounts for more revenue than its consumer business, as CNBC previously reported.
The enterprise segment is shaping up to be a crucial revenue engine as OpenAI prepares for what is widely expected to be a blockbuster IPO. The company confidentially filed its prospectus with the Securities and Exchange Commission in June, though it has not officially set a debut date. Friar recently told employees that OpenAI “will be a public company in 2027,” but added that the company could go public sooner if “our business continues to inflect.”
