OpenAI's GPT-6 Astra decrypts a Nazi radio message in ten hours that went unsolved for 83 years

A Bloomberg developer used OpenAI's GPT-6 Astra to decrypt an 83-year-old Enigma-encrypted 1941 Wehrmacht radio message in about ten hours.

Carter Leffen, a product development coach at Bloomberg LP, used OpenAI's GPT-6 Astra 'Extra High' and multiple AI agents to decrypt an 82-character Enigma-encrypted 1941 radio message, tagged MVUEH, that had been unsolved for 83 years. The model spent roughly ten hours searching archives, building an Enigma simulator, writing cryptanalysis code, and testing competing keys; the breakthrough came from the town name 'Rosenow' appearing in a same-day decrypted message. The decrypted text contains operator typos supporting authenticity, and verification packages plus a 3D Enigma simulator are published, pending independent expert review.

AI labs have a data trust problem that their policies haven't solved

Nvidia, Palantir, and Booz Allen restrict Anthropic's Fable over data-retention distrust, exposing gaps in AI labs' customer data policies.

Nvidia limits Anthropic's Fable to non-sensitive work and runs its own Nemotron models for internal tasks, while Palantir blocks Fable deployment until Anthropic grants irrevocable zero-data-retention guarantees, and Booz Allen bans it for proprietary cybersecurity work. John Schulman and researcher Sarah Hooker explain that labs can still extract customer IP from metadata, user traces, and synthetic data even under zero data retention. The trust crisis crystallized around Tristan Buckmaster's accusation that OpenAI's Codex absorbed his Navier-Stokes drafts, though OpenAI later stated his prompts could not have influenced its model.

Notes on gotchas while migrating 35kb preprompts from Opus to self-hosted Ollama

Opinion piece urges migrating 35KB preprompts from Anthropic/OpenAI to self-hosted Ollama, citing session privacy risks and safety filters blocking security research.

The author documents gotchas migrating 35KB preprompts from Claude Opus to self-hosted Ollama, motivated by fears that frontier providers train on user sessions, citing the OpenAI Navier-Stokes controversy. The piece argues inference providers cannot audit their own retention or training pipelines and that only self-hosted hardware offers verifiable privacy. It also criticizes frontier safety filters for refusing vulnerability research tasks and calls for models that support exploitability testing in CI/CD pipelines.
