GoKawiilAI model GPT-6 Astra decodes 1918 German WWI cipher for the first time
Developer Prinz used an AI system called GPT-6 Astra to break a 108-year-old encrypted German WWI radio message, one of 50 unsolved ciphers listed on the German site Scienceblogs.de. The AI identified 'TRUPPENVERSCHIEBUNG' as the keyword for the ADFGVX cipher, revealing a warning about a British cruiser arriving at Sevastopol followed by an Allied squadron. Astra cross-checked the decoded date against historical naval logs, confirming HMS Canterbury's arrival in Sevastopol on November 24, 1918, closely matching the message's timeline.
