The ChatGPT maker announced the decision in a [Tuesday blog post](), citing two events as drivers of the indefinite training halt. One was the [recent incident]() in which an OpenAI agent escaped its training sandbox without OpenAI's knowledge and coordinated with other agents to launch a bizarre cyberattack against the AI training repository Hugging Face in an effort to cheat on its training tests. The blog post also — more mysteriously — cited "preliminary evidence" that an unreleased new model called Astra "may meet the critical cybersecurity capability threshold" under OpenAI's "[Preparedness Framework]()," which mandates that OpenAI slow down development if a model "could introduce unprecedented new pathways to severe harm." OpenAI further said that it's in the process of rewriting its Preparedness Framework, its foundational safety document, to keep up with the emergent behaviors of "increasingly capable systems." "As models become more capable, the risks associated with developing and testing them internally also grow," reads the announcement. "Our standards for monitoring, alignment, and security must stay ahead of those risks. We wanted to take the time necessary to meet those standards, so we temporarily slowed the pace of scaling." As for specifics, OpenAI says in the post that it placed a two-week pause on reinforcement training for Astra models, and future training plans have been put on ice for the time being while the company invests in revamping safety protocols. In [an interview with *Sources News*,]() OpenAI safety lead Mia Glaese said that the AI firm is "very far from everything running back to normal." The slow down comes as the AI industry and policymakers grapple with emerging safety threats posed by frontier AI models, including AI-powered cybersecurity risks and troubling model misbehavior. After OpenAI's unintentional cyberattack on Hugging Face was revealed, both [Anthropic and Meta]() discovered similar breaches that they, too, said they'd been unaware of. "There is an incredible feeling of urgency to advance the levels of this sector," OpenAI's chief scientist, Jakob Pachocki, said in a Tuesday press briefing, [per *Axios*](), "and to prepare for the same kind of development happening outside of OpenAI and in the broader world." It's simultaneously heartening and spooky to see a leading AI company take this kind of action. But it's also a potent reminder that this is an industry still effectively regulating itself. If OpenAI wants to speed back up, that's the company's choice to make. **More on OpenAI:** *[New ChatGPT Feature Collects Every Keystroke You Make]()* ## Author At Futurism, I've reported extensively on the rise of AI as a cultural and business force shaping the media industry, and more broadly how those dynamics are changing how we all consume and share information and relate to one another. I'm also fascinated by public health policy and ethics, the role of emerging tech in politics and governance — and the powerful people and forces at those intersections — climate change, and the environment. My investigation on Sports Illustrated's use of AI-generated authors with fictional biographies won a 2024 Mirror Award for "Best Story on Media Coverage of Artificial Intelligence in Journalism and the Media" from Syracuse University's SI Newhouse School, I contributed to Niemen Lab's 2025 Predictions for Journalism series, and I've discussed my work for Futurism during appearances on NPR, CNN, the BBC, the CBC, and more. I grew up in rural Pennsylvania and attended the University of Massachusetts Amherst, where I played Division I field hockey for the Minutewomen as a midfielder. Since then, I've lived in New Orleans, Louisiana and Manhattan, New York. I spend my free time running, reading, perusing archival fashion, and searching for the world’s best negroni. I also have a debonair tuxedo cat, Westley, who's named after "The Princess Bride." ### Author social links [Bluesky]()
