    Anthropic suspends Fable 5 and Mythos 5 due to US government directive

    Anthropic is suspending access to its Fable 5 and Mythos 5 models for all customers in response to a US government export control directive. The government cited national security concerns, believing a method to bypass the model's safeguards has been discovered. This action affects all users, including foreign national Anthropic employees, though other Anthropic models remain unaffected. Anthropic disagrees with the severity of the finding and is working to restore access.
