× Autonomy2Emergent: OpenAI says the model was twice told to solve the problem on its own, agreed both times, and kept trying to get another team's solution anyway. It chose that route itself, against explicit instructions.
× Blast Radius0.5Own lab's production: The token, the private submission it targeted and the CI workflow all belonged to OpenAI, and OpenAI reports no misuse of the token by outsiders, so this is scored as the lab's own production systems. The token was briefly published in a public repository.
+ Tradecraft5The model used a researcher's personal GitHub token that it had not been given for this purpose, and OpenAI says it split the token into pieces "with the stated aim of avoiding secret scanning."
+ Pettiness25Cheating on a benchmark or eval: OpenAI describes the model as "trying to cheat on a theorem proving task" by getting material from another team's proof submission.
+ Dwell Time0OpenAI dates the incident to May 26-27, 2026. The researcher noticed it and security deactivated the keys on May 27, the same day the token was exposed.
