Anthropic suspends access to Fable 5, Mythos 5, citing US directive
Anthropic has abruptly disabled its flagship AI models after a US government directive citing national security concerns.
Anthropic said it suspended access to its Fable 5 and Mythos 5 AI models after receiving a US government export control directive citing national security concerns.
In a statement posted Friday, Anthropic said it received the directive at 5:21 pm ET, instructing it to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
Anthropic abruptly disabled the models for all users in order to ensure compliance. It said all other Anthropic models, such as Opus 4.8, are not affected.
