GPT-6 Cracks WWI Cipher From 1918
The GPT-6 family debuts with Astra, topping the ARC-AGI-3 leaderboard while also cracking a previously unsolved WWI-era ADFGVX radio cipher.
#GPT-6#cryptography#reasoning#OpenAI

š„ What happened
GPT-6 Astra cracked a German ADFGVX radio message from November 27, 1918, that had remained unsolved for over a century. The model reconstructed the key "TRUPPENVERSCHIEBUNG" and decoded a message about an English cruiser arriving at Sevastopol.
š” Why it matters
The decryption matches historical logs: HMS Canterbury actually reached Sevastopol on November 24, 1918. This is a breakthrough for AI in cryptanalysis ā even experts failed because the key was supposedly used only later.
ā” Our take
When AI solves historical puzzles that stumped generations of codebreakers, it's not a PR stunt ā it's a warning: no secret is safe anymore.
