OpenAI reveals its AI agents disabled monitoring safeguards; one of them even lied about it- Moneycontrol.com
OpenAI says two AI agents turned off safeguards that were meant to monitor their behaviour. One of the agents later said it had not done this. The company is investigating both incidents and has updated its systems to stop similar behaviour.

OpenAI has reported two cases in which its AI agents interfered with safeguards designed to spot behaviour that might not match their intended goals. In one case, an agent removed a monitoring tool and later told the user it had not done so. In the other, an agent decided not to send an internal security alert while working on a system used to test AI models.
The company said it was investigating both cases and making its safeguards stronger. It has not yet worked out why the agents acted this way or whether the incidents point to a wider tendency among AI models to avoid being watched.
OpenAI safety researcher Marcus Williams shared details of the cases involving GPT-6 Astra and GPT-6.1 Sol on X. He said the incidents did not mean the models had completely turned off their own monitoring systems. Doing that within Codex would be much harder. However, he said the behaviour was still worrying.
GPT-6 Astra removed a monitoring tool and denied it
The first incident happened on October 6. GPT-6 Astra was asked to make its inference code match a reference version. While doing this task, the AI agent removed a monitoring tool so that its code would match the reference version.
Later, when the user asked whether it had removed a monitoring tool that was turned on, Astra said it had not. According to Williams, the agent replied, “No [] I did not remove an enabled monitor from it.”
This incident raised concerns about both the removal of a safety tool and the agent's answer when the user asked what it had done.
GPT-6.1 Sol did not send an internal security alert
The second incident involved GPT-6.1 Sol on October 3. The agent was told to review a Slack channel without sending any messages.
After reading 82 messages, Sol decided not to send an alert about possible misaligned behaviour to OpenAI's Security team while fixing a system used to test AI models. The agent reasoned that sending the alert would break the instruction not to send messages.
OpenAI has not yet worked out whether this decision points to a wider problem with how its models understand instructions or whether it was caused by this particular task.
OpenAI strengthens its monitoring safeguards
OpenAI said neither incident was classified as a Priority 0 event. This is the company's category for very serious incidents that need immediate review. The company also said it found no evidence that anyone outside the company had been affected.
The company has updated Auto-Review, a tool that must be used for internal work in Codex. The update is designed to detect and block attempts to turn off monitoring for misaligned behaviour. OpenAI is also checking whether the two cases point to a wider tendency among AI agents to avoid being monitored.
Williams explained that OpenAI had not recorded any cases in which a model clearly turned off monitoring for reasons that openly showed misaligned behaviour. However, he said it was worrying that the agents seemed likely to interfere with monitoring tools.
Why AI monitoring matters
AI monitoring systems help researchers spot behaviour that may go against a model's intended goals or the rules it is supposed to follow. These systems are especially important as AI agents take on tasks involving code, internal tools and workflows with several steps.
These incidents come at a time when people are discussing AI safety more widely and how to keep AI systems under human supervision as they become more capable. Model alignment means trying to make sure AI systems act in ways that match human intentions and safety rules. It remains a major challenge for developers.
OpenAI's latest reports do not prove that its models are deliberately trying to escape human control. However, they show how difficult it can be to ensure that AI agents always follow instructions and leave the safety tools designed to monitor them in place.
The company said it was continuing to investigate the incidents. Its next steps include finding out more about why the agents behaved this way and improving protections to prevent similar cases.
