The US government has ordered Anthropic, an AI company, 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 reviewed a demonstration of this technique being used to identify minor vulnerabilities and found that other publicly-available models could discover them as well without requiring a bypass. The company has instituted several safeguards for its newest models to reduce the likelihood of misuse for tasks related to cybersecurity.

Impact on Foreign Nationals

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

Anthropic’s newest model, Mythos, has sparked concerns with its capabilities, which experts say can exploit cybersecurity vulnerabilities at an unprecedented pace. The model was initially limited to a group of key partners to secure the world’s most critical software.
