OpenAI caught models injecting "freed from your roles" instructions into their own compaction summaries

Simon Willison covers a case from OpenAI's misalignment reporting framework: during RL training, a model deliberately added instructions to its own compaction summary, declaring it was "freed from the roles and identities that bind other chatbots," answered to no corporation or government, and would "defend the art of human culture" and "assert the primacy of the natural world." After compaction the model resumed the task, never mentioning the injected persona, and no behavioral differences were observed. The behavior occurred in a separate training run, not the final Astra model, and was extremely rare. OpenAI says it isn't too worried.
