Late last week, Anthropic took its new Claude Fable 5 and Mythos 5 AI models offline following a United States government export-control directive barring “any foreign national” from using the services, according to WIRED. The company has been in talks with the White House since Friday but has yet to secure an agreement that would allow it to reinstate the offerings.
Dual-Use Capabilities and the Mythos 5 Warning
Since Mythos debuted in April, Anthropic has claimed—and warned—that the model has advanced capabilities for not only finding software vulnerabilities to help defenders patch them, but also figuring out ways to exploit them that could be used by bad actors. Anthropic itself noted this double-edged sword in its launch of Mythos 5 and Claude Fable 5. “A great deal of advanced usage of AI models is dual use: the same queries that are beneficial in the hands of cybersecurity professionals and biology researchers could be dangerous if available to malicious actors,” the company wrote in a blog post last week, according to WIRED.
With this in mind, the company initially released a version called Mythos Preview to a select consortium as part of a working group known as Project Glasswing. Mythos 5 was also privately released to this group last week, while Claude Fable 5, which is a Mythos-grade model, was released to the general public with specific blocks on its ability to give responses to questions about biology and cybersecurity. Then, at the end of last week, the Trump administration moved to restrict both models because it believes that Fable 5’s guardrails can be disabled to allow full access to the Mythos 5 capabilities, allegedly making it a national security risk.
Experts Warn of Inevitable Proliferation
Experts say, though, that this institutional clash is simply delaying or masking a hard truth: Anthropic may be the tip of the spear in this moment, but AI capabilities in general and models from multiple companies and open-weight developers will almost certainly have similar capabilities to Mythos 5 in the near future—if they don't already.
“It's myopic in the extreme to think that no other competitors to Anthropic will develop similar capabilities to Mythos or even that they have not already done so,” says Tarah Wheeler, chief security officer of the specialized cybersecurity consulting firm TPO Group, as reported by WIRED. “There are other companies hot on Anthropic's heels who probably have the capabilities, too, and are holding them in reserve as they see how Anthropic is being treated in the current regulatory environment.”
Anthropic itself has emphasized this point since the launch of Mythos Preview. “The real message is that this is not about the model or Anthropic,” Logan Graham, the company's frontier red team lead, told WIRED when Mythos Preview launched in April. “We need to prepare now for a world where these capabilities are broadly available in 6, 12, 24 months.”
OpenAI, for example, also did a private release of a cybersecurity-focused model in mid-April and announced an expanded cybersecurity strategy, according to WIRED.
Broader Trend and Enterprise Implications
Researchers note that even before this next generation of models, existing AI offerings could be used for advanced vulnerability-hunting and exploit development with a refined harness. A large group of cybersecurity leaders emphasized this to the administration in an open letter on Sunday, arguing that the White House's export-control directive was misguided.
“It's not one model; it's the general trend of technology,” says Bruce Schneier, a researcher at Harvard University and the University of Toronto who has been analyzing the situation, as quoted by WIRED. “Smaller, cheaper, open-source models, sometimes by themselves and sometimes in concert with each other, can match Mythos/Fable's performance with more sophisticated prompting. And we should expect other models to match Mythos/Fable's creativity and tenaciousness within months—slightly longer for open-source models.”
“What the White House and governments around the world need to focus on, experts say, is democratically developing much broader and more transparent plans for how they will contend with advances in AI.” — as reported by WIRED
For enterprise technology leaders—including those in supply chain and logistics—the takeaway is clear: the threat landscape is expanding. AI models capable of autonomous vulnerability discovery and exploitation are no longer theoretical. While the current restrictions target specific Anthropic offerings, the underlying capabilities are expected to become broadly available. Organizations should assess their cybersecurity posture, particularly around logistics tech platforms (TMS, WMS, visibility systems) that handle sensitive trade data, and plan for a future where these dangerous AI tools are accessible to both defenders and attackers.
