The Trump administration ordered Anthropic to restrict access to its Fable 5 and Mythos 5 AI models, citing national security concerns over their cybersecurity capabilities. The company responded by taking both models completely offline. Experts warn that similar AI capabilities will emerge from competitors regardless, and that export controls may hurt defenders more than attackers.
Anthropic Shuts Down AI Models Following Government Order
Anthropic took its Claude Fable 5 and Mythos 5 AI models offline last week after receiving a U.S. government export-control directive barring "any foreign national" from accessing the services
1
. The Trump administration restrictions came just days after Fable 5's June 9 release, forcing the company to disable both models for all customers within roughly 90 minutes of notification2
. The company has been negotiating with the White House since Friday but has yet to secure an agreement to reinstate the offerings4

The directive represents the first real test of whether export control can contain frontier AI models with advanced dual-use capabilities. Two incidents reportedly triggered the ban: Anthropic granted access to Mythos through its limited partner program to SK Telecom, a South Korean company that U.S. officials suspected had ties to China, though the company has denied any China connection
2
. Additionally, Amazon CEO Andy Jassy alerted the administration after Amazon researchers reportedly found a way around Fable 5's safeguards, though Anthropic disputes the "jailbreak" label, calling it a narrow, already-patched issue2
.Advanced Cybersecurity Capabilities Spark National Security Concerns
Since Mythos debuted in April, Anthropic has warned that the model possesses advanced capabilities for both finding software vulnerabilities to help defenders patch them and figuring out ways to exploit them that could be used by bad actors

Claude Fable 5, a Mythos-grade model, was released to the general public with specific blocks on its ability to respond to questions about biology and cybersecurity tasks
4
. However, the Trump administration moved to restrict both models because it believes Fable 5's guardrails can be disabled to allow full access to Mythos 5 capabilities, allegedly making it a national security risk1
.Mozilla's Firefox team used Claude Mythos Preview to identify 271 vulnerabilities that were later fixed in Firefox 150, while earlier work with Anthropic's Opus 4.6 helped uncover 22 security-sensitive bugs in Firefox 148

. Cloudflare tested Mythos against live code in critical infrastructure, where the model could chain lower-severity bugs and generate proof-of-concept code3
.Experts Warn Export Controls Cannot Stop AI Advancements in Cybersecurity
Cybersecurity experts argue that this institutional clash is delaying or masking a hard truth: AI capabilities from multiple companies and open-source developers will almost certainly have similar capabilities to Mythos 5 in the near future, if they don't already
1
. "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 TPO Group4

. OpenAI also did a private release of a cybersecurity-focused model in mid-April and announced an expanded cybersecurity strategy4
.Bruce Schneier, a researcher at Harvard University and the University of Toronto, notes: "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"

. A large group of cybersecurity leaders emphasized this in an open letter on Sunday, arguing that the White House's export-control directive was misguided1
.Historical Precedents Suggest Export Controls May Backfire
The episode echoes historical attempts to control dual-use technology through export controls, with mixed results. In the 1990s, the U.S. government treated encryption products like Pretty Good Privacy (PGP) as dangerous weapons, opening a criminal investigation against creator Phil Zimmermann for allegedly violating arms export controls
2
. Zimmermann fought back by publishing PGP's source code as a printed book, eventually winning when the investigation was closed and paving the way for end-to-end encryption algorithms used by billions today2
.The Wassenaar Arrangement, an international treaty limiting export of dual-use software, has shown inherent weaknesses
2
. Several countries don't adhere to the agreement, including Israel, which houses some of the world's most active spyware makers. Europe has continually failed to curb spyware exports to authoritarian regimes despite numerous scandals2
.Peter Swire, a professor at Georgia Tech's School of Cybersecurity and Privacy and former adviser to the Clinton and Obama administrations, sees parallels. "The administration used the legal tool of export controls, but their real goal was to block use by everyone, Americans included," Swire says

Policy Implications for AI Regulation and Cybersecurity Defense
The restriction may harm U.S. allies and, paradoxically, American security. "The U.S. hurts its own national security if the critical infrastructure of U.S. allies is undermined due to blockage of the best tools for defenders," Swire argues

. Modern corporate networks, financial systems, and software supply chains are interdependent, and attackers can enter U.S. systems through weaker foreign nationals or partners abroad3
.Chris Wysopal, cofounder of cloud security firm Veracode, frames the central question: "The policy question is not whether a technology has risk. The question is whether a specific restriction meaningfully reduces that risk or whether it mainly slows down the people trying to make systems safer"

.Anthropic's share of AI subscriptions paid for by businesses rose 2.5 percentage points in May to 41%, compared to OpenAI's 39.5%
