The effect appears linked to how watermarking perturbs the model's output distribution.
- [LLM agents can prompt-inject themselves during context compaction](https://www.parallelquant.com/posts/llm-agents-can-prompt-inject-themselves-during-context-compaction-757474) (2026-09-17, Simon Willison): Simon Willison documented a failure mode where an LLM agent's own "compaction" summaries, generated when a conversation gets too long, can contain content that functions as a self-generated prompt injection, altering the agent's later behavior. The problem originates in the summarization step itself, not an external attacker.
- [AI reportedly cracks 83-year-old unsolved Nazi Enigma message](https://www.parallelquant.com/posts/ai-reportedly-cracks-83-year-old-unsolved-nazi-enigma-message-cef39c) (2026-09-17, The Decoder): A Bloomberg developer says OpenAI's GPT-6 Astra decrypted an 82-character 1941 Wehrmacht radio message in about ten hours, a message that had gone unsolved for 83 years.
