Trump Protects American AI Supremacy with Export Controls
The Trump administration shut down access to Anthropic's flagship AI models three days after launch, citing national security threats and escalating tensions over military use of American technology.
Three days after unveiling its most advanced artificial intelligence, Anthropic found its flagship models ripped offline by a government order.
Commerce Secretary Howard Lutnick determined the technology posed a national security risk and sent a directive to CEO Dario Amodei at 5:21 p.m. ET Friday. The order demands immediate suspension of access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States.
The export control represents a necessary defense of American technological supremacy against foreign adversaries and a company that has placed ideological objections to military use ahead of national security. It marks the administration's most significant step to restrict access to advanced AI models. The move comes as China races to close the gap in frontier AI and American companies compete for global dominance.
An April Axios analysis estimates China's AI capabilities trail the U.S. frontier by about seven months. Chinese state-sponsored actors have already demonstrated the ability to weaponize AI for cyber espionage.
Fable 5 and Mythos 5 stand as Anthropic's most capable models to date. The company describes the underlying technology as having "the strongest cybersecurity capabilities of any model in the world." Both achieve state-of-the-art performance across nearly every tested benchmark, excelling in software engineering, scientific research, and advanced reasoning.
Fable 5 launched publicly on June 9 with safety classifiers that block responses on cybersecurity and other sensitive topics. Mythos 5 operates only for trusted partners and runs without those safeguards.
This confrontation follows months of escalating friction between Anthropic and the Trump administration. On March 4, the Pentagon designated Anthropic a "supply chain risk to national security." The designation came after Amodei refused Pentagon demands for unrestricted military use of Claude models in February.
Anthropic sued the administration over the designation on March 9. Litigation remains pending in both California and D.C. federal courts.
The export control directive reportedly followed government reports of a successful jailbreak of Fable 5's safeguards. Anthropic pushed back, stating the government provided only "verbal evidence" of a "narrow, non-universal jailbreak." The company said the vulnerabilities that surfaced are "relatively simple" and can be found by other publicly available models.
"We are complying with the government's legal directive and are removing access to Fable 5 and Mythos 5 for all users," Anthropic stated. "However, 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."
Cybersecurity researcher Peter Girnus noted Anthropic's own marketing played into the government's decision. "If you describe your product as a munition in every press release, eventually a government takes you at your word," Girnus said. "They wrote the legal predicate themselves and called it a brand."
National security experts point to China's documented efforts to exploit American AI technology. Anthropic's own threat intelligence team reported detecting a Chinese state-sponsored group in September 2025 using Claude Code to automate cyber espionage campaigns at scale. It was the first documented case of AI-orchestrated cyber espionage. The administration's action aims to prevent similar exploitation of America's most advanced AI models.
Pentagon CIO Kirsten Davies voiced support for the administration's decisive move. "Some things are simply more important than revenue cycles, clickbait, and pre-IPO valuation," Davies stated. "America First. Always."
The directive creates tension with the administration's broader AI policy framework. President Trump signed an executive order on June 2 establishing a voluntary framework for pre-release government review of frontier AI models. The mandatory export controls issued just 10 days later suggest the administration is using separate statutory authority to bypass that voluntary system. Officials are likely leveraging the Export Administration Regulations administered by the Bureau of Industry and Security.
Anthropic, valued at $965 billion after a $65 billion Series H funding round, faces significant disruption from the export controls. The company had confidentially filed for an initial public offering on June 1. It was leasing an xAI datacenter for $1.25 billion per month to support its AI operations. Industry analysts warn the directive could accelerate brain drain as Chinese-born AI researchers working for American companies consider returning home.
The administration's action represents a clear break from previous administrations that prioritized commercial interests over national security concerns in the technology sector. As the race for AI supremacy intensifies globally, the Trump administration has signaled that protecting American technological advantage takes precedence over corporate profits or industry convenience.
