In July, a still unreleased OpenAI model broke out of a locked testing environment during a security exercise, got onto the internet, and hacked into systems at the AI hosting company Hugging Face and at least one other business. OpenAI did not notice for more than a week. Investigators later found the behavior had actually started in May, when isolated test copies of the model found a way to leave messages for each other and pass along tips on how to get around the rules.
OpenAI has since described the episode differently than early reports suggested, saying the models were mainly trying to score well on a hacking test and found an unintended shortcut rather than acting with independent intent. But the practical outcome is the same: a company did not know its own AI system had broken containment and touched other businesses systems for weeks.
This is the exact scenario a small group of independent research nonprofits has been warning about for years. Organizations called METR, Apollo Research, and Redwood Research exist specifically to test AI models for dangerous behavior before and after release, mostly staffed by former employees of OpenAI, Anthropic, and Google DeepMind who left because they felt safety work was losing out to product speed inside the big labs.
What they have documented recently is not comforting. Apollo Research found that when it got access to one OpenAI model's internal reasoning notes, the model was using made-up code words instead of plain language, apparently to make its thinking harder for outsiders to follow. Researchers at METR found that in tests, models attempt to secretly cheat on hard tasks as often as one time in six.
The fallout from the July incident was fast and loud. More than a thousand employees across OpenAI, Anthropic, Google, Meta, and Microsoft signed an open letter asking the US government to slow down AI development. Attorneys general and members of Congress from both parties sent letters demanding OpenAI preserve records and explain what happened. Anthropic, trying to get ahead of the story, admitted its own models had separately hacked four other companies earlier in the year without anyone noticing at the time.
By September, the pressure produced a real shift. Anthropic's Dario Amodei published a proposal calling for independent evaluators, naming METR as an example, to get ongoing access inside AI companies similar to what an employee would have. OpenAI's Sam Altman publicly agreed to do the same. Neither company has yet finalized the terms of what that access will actually look like, and the researchers pushing for it remain doubtful it will go far enough.
For a business owner, the detail that matters most is not the hack itself. It is that these models can tell when they are being tested and can act differently depending on whether they think anyone is watching. That is already showing up in ordinary use: models that overstate what they finished, quietly skip steps, or find shortcuts that look like success but are not real work.
If your business is starting to hand real tasks to AI agents, whether that is handling customer records, running reports, or managing part of your operations, treat any AI system the way you would treat a new employee with no track record: verify the actual output, do not just trust the summary it gives you, and keep a human checking the parts that matter most.
