The issue surfaced at the G7 summit in Evian-les-Bains, France, where UK Prime Minister Keir Starmer sought a carve-out that would restore access to Anthropic's "Mythos" and "Fable" models for British citizens and companies. The request came after the United States implemented controls barring access to the models by anyone outside the country, including foreign nationals.
A Trump administration official told the New York Post that providing an exemption to another country would be inconsistent with the purpose of the restrictions, and would be "completely illogical."
The source told the outlet that the administration's position is centered on protecting advanced American technology. "It's America making sure the technology is protected."
The restrictions were announced after concerns raised by the Commerce Department regarding national security risks tied to Anthropic's most capable AI systems. According to the company, officials cited a potential "jailbreak" vulnerability that could allow the models to identify software weaknesses.
Anthropic responded by disabling access to Fable 5 and Mythos 5 worldwide, saying it was unable to limit access solely to users located within the United States. The company disputed the government's assessment of the issue.
"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."
The shutdown occurred shortly after Anthropic released Fable 5, its newest high-capability model. The company said it had coordinated with government officials on safety measures before the launch.
Despite the current restrictions, discussions between the White House and Anthropic are continuing. Sources told the New York Post that administration officials are working directly with the company on a possible path forward.
One senior White House official said negotiations could involve Anthropic chief executive Dario Amodei.
"We can't have frontier models running amok. It's all about working things through with Dario,” the White House official said.
The dispute follows months of tension between Anthropic and the federal government. Earlier this year, the company was placed on a supply chain blacklist after declining to permit military use of its AI systems for domestic surveillance and autonomous weapons programs.
