Claude Fable 5.1 decoded a centuries-old royalist message hidden in since 1653 (the-decoder.com)

Anthropic's Claude Fable 5.1 has made headlines by successfully decoding the "Cyphral Distich," a royalist message that had remained encrypted since 1653. The AI model solved this intricate number puzzle in just 44 minutes without any human intervention, marking a significant achievement in the field of AI and cryptography. Previous attempts by researchers using other advanced models had failed to yield a verifiable solution, underscoring the innovative capabilities of Claude Fable 5.1 in autonomously navigating complex problems. The breakthrough lies in the clever use of the book itself, where each number corresponds to a word in Sir Thomas Urquhart's text. The initial letters of these words revealed a clear message: a plea for support for King Charles II. Notably, Fable 5.1’s success was attributed to a methodical approach of systematic trial and error, demonstrating that persistence can pay off in AI problem-solving. This development not only highlights the growing potential of AI in tackling historical enigmas but also raises questions about the limits of human and machine collaboration in areas traditionally dominated by human expertise.
