Anthropic, the company behind the popular Claude chatbot, has suspended its new AI models, Fable 5 and Mythos 5, following a directive from the US government. The government instructed Anthropic to prevent any foreign national from accessing the AI company’s latest and most powerful models, citing national security authorities.

National Security Concerns

The US government’s directive was issued by Commerce Secretary Howard Lutnick, with the help of officials from the Commerce Department’s Bureau of Industry and Security. Anthropic said it had to disable access to Fable 5 and Mythos 5 for all customers, not just foreign nationals, to comply with the directive.

Anthropic released Fable 5 and Mythos 5 on Tuesday, trumpeting the new models as the most powerful AI systems it had ever shared. The company said that these AI models are powerful enough to merit strict safety guardrails to prevent malicious or dangerous use.

Company Response

Anthropic said it believed the government’s directive stemmed from “a misunderstanding” and hoped to reinstate access to Fable 5 and Mythos 5 as soon as possible. The company disagreed with the government’s decision, stating that the finding of a narrow potential jailbreak should not be cause for recalling a commercial model deployed to hundreds of millions of people.

The directive is the latest development in a tumultuous relationship between Anthropic and the federal government. In February, President Donald Trump and Defense Secretary Pete Hegseth moved to bar Anthropic’s products from federal agencies after the company sought stronger guardrails on how the Pentagon used its technology.
