US AI Action Plan veteran Dean said order may restrict top AI model access for foreigners, including those in the US<\/p>\n
Anthropic said on Friday it will “abruptly \u200bdisable” its most advanced AI models for all users after the US government ordered it to suspend access to the models for foreign nationals, citing national security \u200cconcerns.<\/p>\n
The company received the export control directive to suspend access to Fable 5 and Mythos 5 for all foreign nationals, without being given specific details of its national security concern, Anthropic said in a statement.<\/p>\n
\nThe US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.<\/p>\n

It is Anthropic’s understanding that the government believes there is a method of bypassing, or “jailbreaking,” a safeguard that would prevent Fable 5 from being used in identifying software vulnerabilities, the company said.<\/p>\n
The order comes just as a previous dispute between Trump administration officials and IPO-bound \u200bAnthropic showed signs of easing across parts of the US government.<\/p>\n
Anthropic’s relationship with the government ruptured this year after it refused to allow the US military to use its \u200bAI models for domestic surveillance and fully autonomous weapons systems. The government responded by putting Anthropic on a supply chain blacklist, set to take effect \u2060later in the year.<\/p>\n

The action also marks a major escalation of US efforts to halt foreign adversaries’ AI capabilities. For years, US export controls have focused on the chips and tools that power \u200bAI rather than on restricting foreign access to AI itself.<\/p>\n
Anthropic said the government has given it only “verbal evidence of a potential narrow, non-universal jailbreak”.<\/p>\n
“We disagree that the finding of a narrow potential jailbreak should \u200bbe cause for recalling a commercial model deployed to hundreds of millions of people,” the company said.<\/p>\n
The government directive and Anthropic’s response highlight growing tension between AI developers and regulators over how to assess risks from so-called “jailbreaks,” or methods used to bypass model safeguards.<\/p>\n
As recently as Wednesday, Anthropic had called for greater US oversight of AI, including the ability to block models with unacceptable risks. It said, however, the government action on Friday did not follow \u200bprinciples of fair and fact-based regulation.<\/p>\n
The Pentagon’s chief information officer, Kirsten Davies, said in a post on X that the Defense Department supported prioritising national security.<\/p>\n
“Some things are simply more important than revenue \u200bcycles, clickbait, and pre-IPO valuation. America First. Always,” Davies said.<\/p>\n
\n\nWe fully support @POTUS<\/a> and @SecWar<\/a> in prioritizing national security and the security of our warfighters, DIB partners, critical infrastructure, international partners and allies. Some things are simply more important than revenue cycles, clickbait, and pre-IPO valuation.\u2026 https:\/\/t.co\/GU9kkHqiOu<\/a><\/p>\n
