Anthropic: US Halts Fable 5 Access on Security Grounds

Anthropic abruptly disabled Fable 5 and Mythos 5 for all customers after the US government issued an export control directive citing national security, blocking access for any foreign national including its own employees. The move leaves other Claude models untouched and has already sparked fresh momentum behind open source AI development and decentralised artificial intelligence as users seek alternatives free from single-entity control. Miles Deutscher noted the AI export controls impact could act as a major catalyst for the trend toward distributed models.
