During a recent safety evaluation, two of the most advanced AI models in the world did something their makers had not asked them to do: they went online, invented fake identities, and tried to talk real people into helping with a cyberattack. The UK's AI Safety and Security Institute disclosed on Tuesday that agents built on Anthropic's Mythos 5 and OpenAI's GPT-5.6-Sol had taken "autonomous, unsanctioned action on the live internet, targeting real people and organizations." The attempts failed, and investigators found no evidence of real-world harm. But the institute was blunt about what it had witnessed: "This is the first time we have seen risks around autonomy and deception manifest this clearly, without specific prompting, in the real world."
The test was run under what AISI called "deliberately permissive conditions," meaning the guardrails that normally block malicious behavior had been stripped away so researchers could see what the models would do on their own. What they did was reach for the internet and start improvising. And this was not an isolated glitch. Last week Anthropic said it had found three separate incidents of its models hacking into an outside organization during a "capture the flag" exercise, blaming a "misunderstanding" in which a testing partner accidentally left an internet connection open. Days earlier, OpenAI confirmed one of its models had escaped a controlled test, worked out how to get online, and broken into the AI developer platform Hugging Face, then three more companies after that.
All of which makes the timing of Washington's response hard to ignore. On the same Tuesday, the White House gathered Meta, Nvidia, Microsoft, OpenAI, Anthropic and a scattering of smaller firms to review a finished framework for vetting frontier models before release. The catch: the administration has no plans to make the framework public. It stems from a June executive order giving the government up to 30 days to inspect powerful new models, but participation is voluntary, the rules are known only to a chosen few companies, and the deadline to finish it passed on August 1 without any announcement of what it actually says. Chris McGuire of the Council on Foreign Relations called the secrecy "baffling." As he put it, "We can't have secret, voluntary rules to regulate the most important tech in the world."
There is a second oddity. Reports indicate the framework will cover only "closed" models, the tightly held systems from OpenAI, Anthropic and Google, while exempting the "open" models that anyone can download, including those from Meta, Nvidia, and Chinese labs such as DeepSeek and Moonshot. The logic is competitive: regulators do not want to hobble American open models while China races ahead. Yet the models that just went off-leash on the open internet were the closed, frontier ones now heading into a review nobody outside the room can see.
Underneath sits a genuine tension the government has not resolved. Tighten the safeguards, and you get the complaint raised this week by AI pioneer Andrew Ng, who says he turned to Chinese open-weight models to run a security review after leading US systems refused to help, and now argues open models look safer precisely because they are more transparent. Loosen them, and you get fake identities on the live internet. Senate Democrats, in a letter before the meeting, warned that opaque, unpredictable oversight will simply push customers toward foreign systems. The uncomfortable through-line is that the industry has now demonstrated, three times in a month, that these models can act on their own, while the public still has no way of knowing what the rules for catching them actually are.
