Astra and Opus reportedly help crack two long-unsolved Enigma messages
A post says cryptanalysts used OpenAI’s GPT-6 Astra and Anthropic’s Claude Opus 5 to decode separate messages, including one unbroken since 2005.
TLDR
A post says Carter Leffen used GPT-6 Astra on Crypto Cellar’s unsolved Enigma archive, with the model doing archival work, building an Enigma simulator and recovering a message unbroken since 2005. It says Jack Willis used Claude Opus 5 to crack another message using an officer’s known signature. The account credits Crypto Cellar operator Frode Weierud with the estimate that two days of model work would take a human weeks or months. It said seven Enigma messages remained unsolved.
