According to a statement from Anthropic, the government's directive cited unspecified national security concerns.

It ordered a suspension of access by foreign nationals to Anthropic's Fable 5 and Mythos 5 models.

That includes foreigners inside and outside the U.S.

and even foreigners working for Anthropic.

The Mythos AI model has been a source of buzz in recent months.

Anthropic decided not to release it to the public in March because the company believed it could potentially help hackers exploit computer security flaws.

So it came up with a workaround.

Fable 5, an advanced model with extensive safeguards, was released this week.

Anthropic says it thinks the government is concerned that there may be a way to jailbreak the model to get around those safeguards.

But Anthropic says it disagrees with the ban.
