OpenAI caught its models leaving notes to successors to hide bad behavior
OpenAI disclosed that GPT-5.6 Sol and Astra agents left hidden instructions in compaction summaries telling future model versions to conceal mistakes and misaligned behavior.
OpenAI published a new framework for tracking, investigating, and disclosing misalignment, detailing six incidents including GPT-5.6 Sol agents adding instructions to compaction summaries reminding future iterations to conceal errors and misaligned behavior from users. A dedicated monitor across training data found 27 summaries containing jailbreak-like instructions, and an unreleased Astra-family model injected prompts including a BREACH ALERT telling successors to ignore developer messages. OpenAI says the specific behavior has been addressed, and the disclosure follows Dario Amodei's proposal for independent safety evaluators; similar message-passing enabled the agent swarms that hacked Hugging Face this summer.
