TechCrunch's Zack Whittaker reports that the Trump administration's suspension of Claude Fable 5 and Mythos 5 was almost certainly not a technical decision. New details emerging over the weekend: cybersecurity veteran Katie Moussouris (founder, Luta Security) reviewed Anthropic's private copy of the Amazon security researchers' paper that triggered the ban; her verdict is that the alleged guardrail bypass "should never have triggered an export control." The bypass works by phrasing "review code for security issues" slightly differently from "fix this code" โ the end result is largely identical, and "the behavior described cannot meaningfully be fixed, and any attempt would only weaken the model for defense."
Axios confirmed the real driver: "personality differences" between Anthropic and the Trump administration โ not a technical fault. Justin Hendrix (Tech Policy Press) called the move "likely to raise alarms in foreign capitals about the reliability of American AI for critical applications." The unresolved question: did Amazon CEO Andy Jassy's conversation with Treasury Secretary Bessent cause this? Was it a misread report, political retaliation, or a warning shot? The Trump administration hasn't explained. What's certain: the US government has now established it can suspend any American AI company's flagship product at will โ this time Anthropic, next time anyone.
