Anthropic suspends latest AI models after US blocks access to foreigners

TL;DR

  • Anthropic suspended its most powerful AI models, Mythos 5 and Fable 5, for all users.
  • The US government directed Anthropic to limit access for foreign nationals due to national security concerns.
  • The directive followed the discovery of a "jailbreak" bypassing the models' safety guardrails.
  • Anthropic stated the order was based on a "misunderstanding" and will halt new model deployments across the industry.
  • The Trump administration had previously experimented with Anthropic's Mythos model.
