US bans foreign access to Anthropic’s Mythos and Fable

A ‘trusted partner’ of Anthropic and US government reportedly raised security concerns around Mythos and Fable.

Countries across the world are reeling from the effects of an abrupt suspension of two of Anthropic’s most advanced AI models following an order from the US government late on Friday (12 June).

Now, senior technical staff from the AI giant are reportedly in Washington to meet with White House officials to try and resolve their second major dispute in months, according to Axios.

In a surprise statement on Friday, Anthropic said that the US government issued an export control directive, ordering the company to suspend access to Claude Fable 5 and Claude Mythos 5 by “any foreign national, whether inside or outside the US, including foreign national Anthropic employees”.

Anthropic stated that it has disabled both Fable 5 – which released last week – and Mythos 5 for all of its customers to ensure compliance with the order.
