Anthropic Disables Claude Fable 5 and Mythos 5 After US Government Order

Anthropic has disabled the Claude Fable 5 and Mythos 5 models following a US government export control directive related to national security. The remaining models, including Opus 4.8, continue to be available, which may impact practitioners relying on the disabled models for their applications. This action underscores the regulatory challenges in deploying AI technologies, particularly in sensitive areas.
