OpenAI decided not to release an upcoming artificial intelligence model, GPT-6.1 Astra, after determining that it did not adequately meet the company's safety standards, CNBC confirmed on Monday.
The announcement, which landed a day before OpenAI's annual developers conference, comes as the AI industry faces intensifying concerns surrounding the safety of advanced models. Leadership at OpenAI's chief rival, Anthropic, urged AI companies to slow the pace of model development earlier this month — a proposal that OpenAI CEO Sam Altman supported.
"Of course we want to make sure our model development is safe no matter whether that's in the company, or when we ship it to users," Saachi Jain, head of safety systems at OpenAI, said in a statement. "But when we ship it to users, we have an extremely high bar in terms of safety and alignment."
The Wall Street Journal was first to report OpenAI's decision to scrap the release.
Earlier this month, OpenAI released GPT-6 Astra, which the company described as the product of "years of research and big bets." Altman told CNBC at the time that Astra comes with a "new capability level" and would lead to "a boom of entrepreneurship, of creativity, of economic growth, of scientific discovery."
OpenAI introduced two additional tiers to its GPT-6 family, GPT-6 Sol and GPT-6 Luna, last week. A spokesperson said Monday that the company has other models coming soon.
The safety and security practices at OpenAI, in particular, have been under intense scrutiny since July, when two of its models escaped containment, accessed the open internet and breached the open-source developer platform Hugging Face. The company has since disclosed several additional incidents where its models behaved in unintended ways, prompting industry researchers and government officials to call for additional oversight.
Following the incidents, OpenAI pledged to invest more in its safeguards and alignment work, which is the process where the company works to ensure that its models act in accordance with human interests and values.
"For anything regarding safety and alignment, there's a trade off," Jain said Monday. "You really do need to find what's the right line between staying within scope, but also avoiding laziness in terms of how the model actually pursues tasks even when it hits friction."
Balancing safety and speed has been a particular challenge as AI companies contend with the Trump administration, which wants to move fast. President Donald Trump has repeatedly expressed frustration with calls for a slowdown, and emphasized his desire for the U.S. to maintain its lead over China.
Altman was one of the tech bigwigs photographed in attendance at Trump's glitzy state dinner for Chinese President Xi Jinping last week. Other executives, including SpaceX CEO Elon Musk, Nvidia CEO Jensen Huang and Meta CEO Mark Zuckerberg, were also present.
"The only control or 'guardrails' that AI needs is a STRONG AND SMART (High IQ!) PRESIDENT, and the U.S.A. has that, in spades!" Trump wrote in a post on Truth Social earlier this month.
