Claude Fable 5.1 decoded a centuries-old royalist message hidden in plain sight since 1653 Anthropic's Claude Fable 5.1 appears to have cracked a centuries-old number puzzle that researchers considered unsolved. The "Cyphral Distich" by Sir Thomas Urquhart, published in 1653, consists of two lines of 32 numbers each. According to Vals AI, Fable 5.1 solved it in 44 minutes with no human help.
