The 82-letter cipher was posted online in 2005 as challenge Nr. 172 and had resisted human cryptanalysts for years. According to the report, Astra selected the target itself, hypothesized a link to another message (Nr. 173, SIPVX), guessed the repeated plaintext \"ROSENOW ROSENOW,\" and wrote its own Python and C++ Enigma simulator and Bombe code to test the hypothesis. The decrypted German text reads \"BTTE UM ANGABE DES MARSQWEGES X BEFINDE MIQ IN X ROSENOW ROSENOW X SOFORT FUNKANTWORT X WASCHBBSCH,\" roughly translating to a request for march route and position at Rosenow with a demand for immediate radio reply. Researchers note the original message contained a spelling error that would have hindered traditional decryption. Crypto Cellar says it is still analyzing Astra's logs to understand the exact reasoning path. Last week, the same model reportedly cracked a 108-year-old WWI ADFGVX cipher.","keyPoints":["ChatGPT-6 Astra decrypted the 1941 MVUEH Enigma message in two days, Crypto Cellar reports","The model chose the target, wrote simulator and Bombe code, and used a \"ROSENOW ROSENOW\" plaintext guess","Decrypted text reveals a German Army position report to the SS-Totenkopf Division"],"whyItMatters":"Shows an LLM autonomously designing cryptanalysis tools and solving a historic cipher that resisted human experts for decades, suggesting new capabilities for code-breaking and historical research.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Crypto Cellar","Tom's Hardware"],"models":["ChatGPT-6 Astra","GPT6-Astra"],"people":["Mark Tyson"]},"firstPublishedAt":"2026-09-26T10:00:00Z","updatedAt":"2026-09-26T10:00:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Tom's Hardware","title":"ChatGPT-6 Astra cracks 1941 Enigma-coded message in two days","url":"https://tomshardware.com/tech-industry/artificial-intelligence/chatgpt-6-astra-cracks-1941-enigma-coded-message-in-two-days-autonomous-ai-coded-its-own-simulator-to-crack-code-that-was-unsolved-since-it-was-shared-online-back-in-2005","publishedAt":"2026-09-26T10:00:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"AI Uncovers Century Old War Cipher","url":"https://digestai.news/thread/chatgpt-6-astra-decodes-108-year-old-wwi-german-cipher","storyCount":3},"cite":{"text":"Digest AI, \"ChatGPT-6 Astra cracks 1941 Enigma message in two days, Crypto Cellar reports\", 26 September 2026, https://digestai.news/story/chatgpt-6-astra-cracks-1941-enigma-message-in-two-days-crypto-cellar-r","publisher":"Digest AI","title":"ChatGPT-6 Astra cracks 1941 Enigma message in two days, Crypto Cellar reports","datePublished":"2026-09-26T10:00:00Z","url":"https://digestai.news/story/chatgpt-6-astra-cracks-1941-enigma-message-in-two-days-crypto-cellar-r"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
