Summary
The article criticizes export control directives targeting AI models like Fable 5 and Mythos, arguing they harm US cyber defense capabilities while failing to impede attackers. The author claims to be one of the few outside experts who has actually read the underlying research paper, and explains that the study used open-source code with known vulnerabilities plus deliberately planted flaws to test AI code review capabilities. When Fable 5 refused to participate, it highlighted the unintended consequence of export controls weakening defensive cybersecurity tools without affecting malicious actors who already have access to the technology.

· 5 pulledThe heavy-handed and hasty export control directive was misguided.
The behavior described in the paper cannot meaningfully be fixed, and any attempt would only weaken the model for defense.
Since I appear to be the only outside expert who has actually read the paper, I can separate the technical facts from the speculation.
Restricting Fable and Mythos has the same unintended consequence of harming defense while doing nothing to impede attackers.
We can't export control our way to cyber resilience.
