GPT-6 Astra Solves a WWI German Radio Cipher

GPT-6 Astra reportedly solved a World War I German radio cipher from a list of 50 unsolved ciphers on Scienceblogs.de. The cipher involved arranging the word "TRUPPENVERSCHIEBUNG" horizontally, with encrypted message letters written below in rows of 19. This method, demonstrated by calculating the positions of letters like 'T' and 'R' to reveal 'A' and 'V' respectively, allowed for the decryption of the message.

This marks the first time GPT-6 Astra has publicly demonstrated its ability to solve a historical military cipher, unlike previous AI decryption attempts on simpler codes.
