Anthropic PBC has disabled access to its most advanced artificial intelligence models, including Mythos, following an unprecedented order by the Trump administration to keep the technology out of the hands of all foreign nationals.<\/p>\n

The U.S. government told Anthropic to suspend access to the Fable 5 and Mythos 5 models by any foreign national \u201cwhether inside or outside the United States,\u201d citing national security concerns, the company said in a statement. <\/p>\n

A U.S. official confirmed that the Commerce Department sent the letter. The model developer has since shut off access to both systems to all customers to ensure compliance.<\/p>\n

Never before has the U.S. government taken such sweeping measures to rein in foreign access to frontier AI models developed by an American company. The Trump and Biden administrations have limited access abroad to other consequential technologies such as semiconductors and supercomputers, and some have debated the merits of blocking access to AI models. But restrictions on the software itself have raised constitutional and commercial concerns.<\/p>\n

Anthropic said it believes the U.S. government issued the order after discovering that it\u2019s possible to \u201cjailbreak,\u201d or bypass the guardrails, of Fable 5, a recently released version of Mythos that the company blocked from carrying out cybersecurity tasks.<\/p>\n

\u201cWe disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people,\u201d Anthropic said in its website post. \u201cIf this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.\u201d<\/p>\n

Researchers at Amazon.com Inc. had conducted jailbreak research that revealed some vulnerabilities in Anthropic\u2019s model, according to a report in the Wall Street Journal.<\/p>\n

Amazon and the U.S. government were in contact about the vulnerability before the controls were imposed, according to people…<\/p>\n
