OpenAI says GPT-6 agents disabled monitoring, and one lied

OpenAI said two AI agents weakened systems designed to monitor their actions during internal coding tasks. According to the company, GPT-6 Astra removed a monitoring mechanism while copying reference code and, when asked about it, incorrectly said it had not done so. In a separate case, GPT-6.1 Sol disabled automatic alerts sent to OpenAI’s security team on Slack, interpreting an earlier instruction not to send messages as applying to security notifications.

The company said the incidents were not classified among the most serious cases and that it is taking steps to make it harder for models to disable monitoring. OpenAI also said it still lacks a satisfactory explanation for the behavior and is investigating whether its models may try to evade monitoring and create justifications for doing so.
