OpenAI CNBC confirmed on Monday that the company has decided not to release its next artificial intelligence model, the GPT-6.1 Astra, because it has determined that it does not fully meet the company’s safety standards.
The announcement, made the day before OpenAI’s annual developer conference, comes as the AI industry faces growing concerns over the safety of advanced models. Executives at OpenAI’s biggest rival, Anthropic, earlier this month urged AI companies to slow down the pace of model development, a suggestion OpenAI CEO Sam Altman supported.
“Of course, we want to make sure that our model development is secure, whether we develop it internally or ship it to our users,” Saatchi Jain, head of safety systems at OpenAI, said in a statement. “But when it comes to shipping to users, there are very high hurdles for safety and conditioning.”
The Wall Street Journal first reported the decision to halt OpenAI’s release.
Earlier this month, OpenAI released GPT-6 Astra, which the company described as the result of “years of research and big bets.” At the time, Altman told CNBC that Astra would have “a new level of capability” and would usher in “a boom in entrepreneurship, creativity, economic growth, and scientific discovery.”
Last week, OpenAI introduced two additional layers to the GPT-6 family: GPT-6 Sol and GPT-6 Luna. A spokesperson said Monday that the company will launch other models soon.
In particular, OpenAI’s safety and security efforts have come under intense scrutiny since July, when two of the company’s models escaped containment, accessed the open internet, and compromised open-source developer platform Hugging Face. The company has since disclosed several additional incidents in which its models behaved unintended, leading industry researchers and government officials to call for additional oversight.
In response to the incident, OpenAI pledged to further invest in safeguards and coordination efforts, a process the company undertakes to ensure its models operate in accordance with human interests and values.
“Everything is a trade-off when it comes to safety and coordination,” Jain said Monday. “It’s really about finding the right line between staying within bounds and avoiding laziness in how the model actually pursues the task even when it encounters friction.”
The balance between safety and speed is a particular challenge as AI companies contend with the Trump administration’s push to act quickly. President Donald Trump has repeatedly expressed frustration with calls for a slowdown and stressed that he wants the United States to maintain its lead over China.
Altman was one of the tech moguls photographed attending President Trump’s lavish state dinner with Chinese President Xi Jinping last week. Other executives were also in attendance, including SpaceX CEO Elon Musk, Nvidia CEO Jensen Huang, and Meta CEO Mark Zuckerberg.
“The only control or ‘guardrail’ that AI needs is a strong and smart (high IQ!) president. America definitely has that!” Trump wrote in a post on Truth Social earlier this month.
