AI Decodes Napoleon-Era Cipher After Over 200 Years Unsolved
Artificial intelligence has deciphered a coded letter from Napoleon Bonaparte's 1809 military campaign after more than 200 years unsolved. AI engineer Carter Church used OpenAI's GPT-6 Astra model to decode the message in six hours, revealing troop positions. The letter had been overlooked in an academic archive due to the labor-intensive nature of traditional methods. Experts note AI is transforming historical cryptography by enabling non-specialists to solve longstanding puzzles, though some ciphers remain challenging.
