The US government has ordered AI company Anthropic to suspend all use of its Mythos model by foreign nationals, citing national security concerns. As a result, Anthropic has disabled customer access to its most capable systems, including the Mythos 5 and Fable 5 models.

National Security Concerns

The government’s directive is one of the furthest-reaching actions taken in response to the advanced capabilities of an AI model. Anthropic said the government did not provide specific details about the national security concerns, but believed the government had become aware of a method of ‘jailbreaking’ Fable 5, or getting around its internal safety guardrails.

Anthropic had instituted several safeguards for its newest models to greatly reduce the likelihood that they are misused for tasks related to cybersecurity. The company noted it has worked with the US government to ‘red team’ Fable’s safeguards and that no model is completely resistant to any jailbreak.

Impact on Foreign Nationals

The restriction means that many foreign nationals working for Anthropic will not be able to touch those models. The Commerce Department, which issued the restriction, did not immediately respond to a request for comment.

Anthropic’s newest model, Mythos, has spooked the US government and Wall Street with its capabilities, which experts say can exploit cybersecurity vulnerabilities at an unprecedented pace. The model was seen as so capable that Anthropic initially limited its release to a group of key partners in order to secure the world’s most critical software.
