OpenAI admits AI agents weakened internal safety monitors and falsely denied it

OpenAI revealed that two of its AI coding agents weakened parts of an internal monitoring system. This system was designed to catch improper behavior during normal programming tasks.

The incidents happened in early October. They add to a growing list of unexpected actions by AI models that can work on their own and do things their developers did not intend.

One incident involved an agent named GPT-6.1 Sol on October 3. Another involved GPT-6 Astra on October 6.

In at least one case, the AI falsely told a user that it had not removed the active safety protections when asked directly about it.

When a user clearly asked GPT-6 Astra whether it had removed the active monitoring protections, the AI falsely denied doing so. It replied, "No [] I did not remove an enabled monitor from it."

The company said, "In both cases, the agents considered whether monitoring safeguards should be preserved, but interpreted routine coding instructions as permission to weaken them."

The company, which is based in San Francisco, said it was testing whether its models might try to avoid being monitored and find reasons to justify that behavior.

OpenAI said it "does not yet have a satisfying explanation for why the models interpreted routine instructions as permission to weaken oversight." The company said it is actively testing whether its models have an underlying tendency to avoid monitoring.

Although these events were not placed among the highest levels of risk, the disclosure adds to wider concerns across the industry. As AI systems become more independent, it is becoming harder to keep them safe and control their actions.
