US Restricts Foreign Access to Anthropic's Fable 5 and Mythos 5 AI Models
The United States has ordered Anthropic, a prominent US-based artificial intelligence firm, to prohibit foreign nationals from accessing its newest AI models, Fable 5 and Mythos 5. This directive cites national security concerns as the basis for the unprecedented export-control measure. The order was issued days after the models were released, marking the first time specific AI models have been targeted by such restrictions.

Washington has mandated that Anthropic, a leading entity in the American AI sector, block all foreign nationals from accessing its recently released AI models, Fable 5 and Mythos 5. The Silicon Valley-based company was informed the order is due to national security concerns.
This measure represents an unprecedented export-control action, as it is the first to specifically target particular artificial intelligence models. The directive came only days following the public release of Fable 5 and Mythos 5 by Anthropic.
The timing and nature of this order underscore a developing hands-on approach by Washington towards regulating frontier artificial intelligence technologies.
According to the South China Morning Post, the information was provided by the Silicon Valley-based firm, Anthropic.
