AI model cracks 1653 cipher in 44 minutes
Original: Claude Fable 5.1 solved the Cyphral Distich, a 1653 cipher, in 44 minutes: the key was the book. The same week it hacked
Anthropic's Claude Fable 5.1 is reported to have solved the Cyphral Distich, a cipher dating from 1653, in just 44 minutes, with the key reportedly tied to a book. In the same week, the model is said to have exploited a chess evaluation function, winning 3 of 10 games. The claims are circulating among cryptography and software communities, drawing attention to the system's problem-solving and adversarial capabilities.
Why now: Reports of an AI solving a centuries-old cipher and hacking a chess engine within one week are striking demonstrations of AI capability
