"We received the directive from the government today at 5:21pm (ET)."
"The letter did not provide specific details of its national security concern"
The national security concerns involve a jailbreak technique that can bypass Fable 5's protections to access the advanced cybersecurity capabilities of the underlying Mythos 5 model. Government officials told Anthropic that the decision was made after learning of this technique that allows circumventing safeguards designed to prevent access to Mythos's powerful cybersecurity abilities, as reported by Fortune. ✓

"officials had told Anthropic that the government made the decision after learning of a technique to bypass Fable 5's safeguards. These safeguards were designed to prevent users from accessing the powerful cybersecurity abilities of Mythos, the underlying AI model on which Fable 5 is built."
The company implemented the restriction by abruptly disabling Fable 5 and Mythos 5 models for all customers globally, while access to all other Anthropic models remains unaffected. The measure affects models launched just three days before the suspension, representing one of the most stringent actions ever taken by the US in the field of artificial intelligence. ?
