Original: The US banned Anthropic’s Fable 5 release, but the numbers don’t seem to care

The US government forced Anthropic to pull Fable 5 and Mythos 5 over a reported guardrail bypass, but adoption metrics appear unfazed.

The US government compelled Anthropic to withdraw its two newest models, Fable 5 and Mythos 5, citing national security concerns after Amazon researchers allegedly found a way to bypass Fable 5's safety guardrails.
