Brute Force and Book Keys: Claude Fable Decodes a 1653 Royalist Cryptogram

Vals AI tasked Anthropic's Claude Fable 5.1 with unprompted cryptanalysis, leading it to solve Sir Thomas Urquhart's 370-year-old Cyphral Distich by indexing directly into the text's own structural paragraphs rather than applying classical frequency analysis. The result is a humbling reminder of human oversight—the solution required no sophisticated math, only methodical patience, though reliance on automated search runtimes risks substituting genuine conceptual breakthroughs for brute-force persistence.

Astra and Fable Stick to 2025 Benchmarks as Alignment Evals Stagnate

By continuing to test frontier models on minor iterations of 2025 alignment frameworks, major labs risk optimizing for legacy safety metrics while subtle, out-of-distribution failure modes go unmeasured. The reliance on familiar tests highlights a growing tension between rapid model scaling and the tedious work of inventing rigorous, modern evaluation paradigms.
