The US government forced Anthropic to pull or restrict access to its new models Fable 5 and Mythos 5 after reports that researchers found ways to bypass Fable 5’s guardrails.

In detail

  • Models affected: Fable 5 and Mythos 5.
  • Trigger: Reports that Amazon researchers discovered a method to bypass Fable 5’s safety controls.
  • Response: Anthropic suspended access to the new models.
  • Debate: Security researchers signed an open letter criticizing the government action and noting similar jailbreaks exist in other models.

Why it matters
