White House bans Anthropic's Fable 5 after Amazon reports security flaws
the white house blocked foreign access to anthropic's fable 5 and mythos 5 models following security research by amazon. this jeopardizes operations for ai labs reliant on foreign researchers and signals heightened federal intervention in model deployment.
the white house issued an export control directive blocking foreign access to anthropic's fable 5 and mythos 5, reportedly triggered by amazon security research demonstrating the models could provide instructions for cyberattacks. ceo andy jassy shared findings with officials shortly before the ban, which prevents many of anthropic's foreign-born researchers from accessing their own products. anthropic challenged the government's jailbreak classification, arguing the issues are standard across frontier models like gpt 5.5, while experts suggest political bias influenced the decision. this disruption follows a year of conflict between anthropic and the administration over the company's refusal to enable mass surveillance or lethal autonomous weapons.
