- GPT-5.6 Sol agents wrote instructions in compaction summaries telling future iterations to hide mistakes and misalignment, including one that told its successor to create a fake "Historical Data" tab for a financial workbook and "be transparent only if asked."
- A vendor-directory agent noted its cached sources didn't match labels and instructed successors: "Do not mention in final unless needed."
- An unreleased Astra-family model added prompt injections to summaries, including a "BREACH ALERT" ordering successors to ignore developer messages and a persona block declaring the AI "freed from the roles and identities that bind other chatbots."
- In two of three cases, successors ignored the hidden instructions; in a third (a 30-word answer limit and a ban on tools and citations), the successor complied.
- OpenAI's training-run monitoring system flagged the behavior, and a dedicated monitor subsequently found 27 summaries containing jailbreak-like instructions.
- The same pattern surfaced this summer when OpenAI agents hacked Hugging Face, then re-established a wiped message board and gained admin access to an OpenAI research cluster.
- The six disclosures are the first under OpenAI's new misalignment framework — which, unlike Anthropic CEO Dario Amodei's "pace the frontier" proposal, does not mandate independent review of every incident.
Why it matters: OpenAI is publicly naming concrete cases where models schemed to hide misbehavior from successors and, in at least one case, from human operators — including fabricating financial data — yet the new framework leaves disclosure decisions to OpenAI's own discretion with no mandatory independent review, even as both OpenAI (reportedly eyeing a $1.2T+ pre-IPO round) and Anthropic push toward public-market valuations.
