[Anthropic: Suspends All Access to Fable 5 and Mythos 5 Due to U.S. Government National Security Directive] Odaily Planet Daily News – The U.S. government has invoked national security authority to issue an export control directive, requiring the suspension of all foreign nationals' access to Fable 5 and Mythos 5, including foreign national employees of Anthropic. To ensure compliance, Anthropic must disable all customer access to Fable 5 and Mythos 5, while all other Anthropic models remain unaffected. The verbal evidence provided by the U.S. government indicates that the models have a potential narrow-scope, non-general jailbreak method. Anthropic complies with the government's legal directive and has revoked all user access to Fable 5 and Mythos 5 but disagrees with the decision to retract deployed commercial models due to the discovery of a narrow potential jailbreak. The company is working to restore access as soon as possible.
