The U.S. government has imposed export controls on Anthropic's Fable 5 and Mythos 5 models, citing national security concerns related to a narrow jailbreak identified by Amazon. This directive requires Anthropic to suspend access for all foreign nationals, including their own employees, leading to a complete shutdown of these specific models.
