Anthropic cuts off Fable 5 and Mythos 5 access following government order

Anthropic blocked access to its Fable 5 and Mythos 5 AI models on Friday evening following a government order citing national security concerns. The directive mandated that access be restricted for all foreign nations, both within and outside the United States, and explicitly included Anthropic employees. In compliance with these demands, the company has implemented a complete cutoff of access to these models for all customers globally. This action impacts users who previously utilized these advanced AI systems for various applications. The specific nature of the national security concerns has not been publicly detailed by the government or Anthropic. The company has not yet provided a timeline for when access to Fable 5 and Mythos 5 might be restored or if alternative models will be made available to affected users. This development highlights the increasing scrutiny and regulatory oversight applied to advanced AI technologies by governments worldwide.
