Following on others solving Ciphers with frontier LLMs, I wanted to give it a try. While I can't validate a new math proof, I can understand translated Ciphertext since its legible (numbers into readable text that makes sense).

So far I've solved or made significant contributions to 6 'unsolved' ciphers, with more in my crosshairs.

Mostly solved with Fable 5.1 and Opus 5.

I've worked on a few 'famous' ones, seemingly finding that there is no message in the Chinese Gold Bar problem.
