Anthropic confirmed tonight that it has disabled access to Claude Fable 5 and Claude Mythos 5 to all customers, following an export control directive from the US government.

“The government believes it has become aware of a method of bypassing, or ‘jailbreaking’ Fable 5,” the company said in a blog post.
