GPT-6 Astra reportedly deciphered a 1918 German radio message

GPT-6 Astra reportedly deciphered a 1918 German radio transmission that had previously been considered unresolved. The proposed translation says an English cruiser arrived in Sevastopol on November 24, 1918, followed by an Allied squadron on November 26.

Astra reportedly checked the interpretation against historical records identifying HMS Canterbury’s arrival in Sevastopol on November 24 and the Allied squadron’s arrival on November 26. The message is described as one of 20 World War I German radio messages on a list of the 50 leading unsolved ciphers. The claim was not independently confirmed in the supplied material, and the boundaries between a cipher, an unknown language and an untranslated text remain uncertain.
