US Order Forces Anthropic to Disable Fable 5 and Mythos 5 for All Users

Anthropic has been compelled by a US government order to disable two of its frontier AI models, Fable 5 and Mythos 5, for all users. The directive, citing national security concerns related to a potential jailbreak that could allow the models to identify software vulnerabilities, required Anthropic to block access for foreign nationals. Due to the complexity of implementing such a restriction rapidly, Anthropic chose to suspend access for all customers to ensure compliance, impacting users globally. This action highlights how geopolitical and national security concerns can now directly influence the availability of advanced AI models, shifting procurement considerations beyond typical vendor reliability.
