GPT-6 Astra cracks a WWI German ADFGVX cipher and cross-checks its own work against naval logs

GPT-6 Astra Solves a WWI German Radio Cipher

GPT-6 Astra decoded a WWI German ADFGVX radio message that had been unsolved for over a decade. It used the key TRUPPENVERSCHIEBUNG to recover a plaintext reporting a British cruiser arriving at Sevastopol on Nov 24, 1918, and an allied squadron following on Nov 26. The model then cross-checked its output against HMS Canterbury's original logs and confirmed the dates. The post doesn't disclose which Astra version was used, token count, or how long the solve took.
