A researcher used GPT-6 Astra to decipher a WWI German radio transmission from 1918, one of the 50 famous unsolved ciphers listed on a German science blog (prinz)
GPT-6 Astra appears to have found a workable key for a 1918 German radio cipher that had resisted human solvers.
The message was one of the “50 unsolved ciphers” collected by Scienceblogs.de. The Techmeme note says the model connected the cipher to wartime context, including logs from an English cruiser, while checking the proposed plaintext. Prinz says the likely reason it stayed unsolved is that the key was thought to have come into use after the message date, leaving this one out of reach. Techmeme's note
