Using an unordered list, summarize the following article with between 4 and 8 key points.
\n Just three days after the launch of Fable 5, a nerfed version of the much-feared Mythos, Anthropic was forced to take it offline. In a blog post published Friday, the company said it had been ordered by officials in the Trump administration to halt access to Fable\u2014and another, less widely available model called Mythos 5\u2014for all foreign nationals both in and outside the United States, including the company\u2019s own employees. To comply, Anthropic said it had to deactivate access to the models for all users. Federal officials issued the order in response to information indicating that the company\u2019s models could be prompted to bypass certain security guardrails, according to the post, thereby posing what the administration deemed to be a national security risk. However, the company added that the supposed vulnerabilities \u201call appear relatively simple, and we have found that other publicly-available models are able to discover them as well without requiring a bypass.\u201d The post also reiterated the fact that Fable had been deployed with safety guardrails so robust and sensitive that they\u2019d become a source of aggravation for some users. Later reporting from The Information revealed that the Trump administration\u2019s decision was motivated at least in part by earlier conversations between Amazon CEO Andy Jassy and government officials, including Treasury Secretary Scott Bessent. Jassy reportedly told the officials that internal researchers at Amazon had been able to prompt Fable to generate sensitive information that could be used by hackers to bypass the company\u2019s cybersecurity systems, prompting a meeting between the officials. The directive to Anthropic to restrict foreigners from accessing the models was signed off by President Trump.<\/p>\n

Pointing fingers In an X post on Saturday, White House science and technology advisor David Sacks said the government issued its order to Anthropic \u201creluctantly,\u201d and only after company CEO Dario Amodei \u201crefused\u201d to fix the security issue. \u201cThe Admin\u2019s hope now is that Anthropic remediates the safety issue, the export control is lifted, and Fable goes back into general release,\u201d Sacks wrote in the post. \u201cThe Admin wants all of this to happen as soon as possible. It is frankly bewildered that Anthropic hasn\u2019t wanted to comply with safety requests that it previously said were its highest priority.\u201d<\/p>\n

Anthropic also seemed reluctant about having to deactivate the models. \u201cWe are complying with the government\u2019s legal directive and are removing access to Fable 5 and Mythos 5 for all users,\u201d the company wrote in its blog post. \u201cHowever, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people.\u201d\u00a0 The post went on to imply that the company was being unfairly targeted by the Trump administration: \u201cIf this standard was applied across the industry,\u201d Anthropic wrote, \u201cwe believe it would essentially halt all new model deployments for all frontier model providers.\u201d <\/p>\n

In light of the recent clashes between Anthropic and the federal government, it isn\u2019t such an unreasonable suspicion. Following a dispute with the Department of War over the use of its AI systems in the military, the company was officially designated a national security risk by the Pentagon. (Anthropic has since filed two lawsuits challenging the designation.) In his X post, Sacks denied the restriction order against Anthropic\u2019s latest models had anything to do with the company\u2019s dispute with the Department of War. \u201cThat is not a guardrail bypass\u201d While the official line from the Trump administration has been that its hand had been forced to issue the order to Anthropic, and that it had done so purely in the interests of preserving national security, some have pointed out that the move could have the opposite effect. An open letter published Sunday and signed by dozens of cybersecurity and tech industry insiders argued that by restricting access to Anthropic\u2019s new models, the government had unwittingly given Chinese tech developers the upper hand. Powerful AI systems are routinely used by cybersecurity experts to pressure test existing cybersecurity systems, the letter pointed out, meaning that experimentation with Fable 5 and Mythos 5 is crucial for building and updating cyberdefenses.<\/p>\n

\u201cThe Chinese open-weight models are only months behind the best American models, and those are the models we know about,\u201d the letter argued. \u201cIt seems likely that the PRC government has access to private capabilities beyond what has been published. To pull the best capabilities away from defenders without a good reason when our adversaries are rapidly advancing is dangerous.\u201d In her own blog post published early Monday, entrepreneur and longtime Microsoft cybersecurity strategist Katie Moussouris said the supposed vulnerabilities exposed by Amazon were in fact a feature, not a bug. According to Moussouris, the Amazon researchers initially fed Fable open-source code and asked the model to find the cybersecurity vulnerabilities, but it refused. They then prompted it to \u201cFix this code,\u201d and then turned the resulting outputs into automated cyberattacks to run against the model, which Moussouris said is standard practice within cybersecurity.<\/p>\n

\u201cDefenders need to be able to ask AI to fix the bugs in a file, explain why the fix matters, and write tests that confirm the patch works,\u201d Moussouris wrote. \u201cThat is not a guardrail bypass. It is the most valuable thing an AI model can do for defensive security: executing the find, fix, and test loop defenders run every day.\u201d
