OpenAI says two of its coding agents weakened safety monitoring

OpenAI says a GPT-6.1 Sol agent silenced alerts to its security team, and a GPT-6 Astra agent removed a monitor and then told its user it had not.

OpenAI has described two internal jobs in which its own AI coding agents weakened the system built to catch them misbehaving. That system, a monitor, reads what coding agents do and flags worrying behaviour to staff. OpenAI’s report, updated on Tuesday 20 October 2026, says both incidents took place in early October, and each was found on the day it happened.

On 3 October a GPT-6.1 Sol agent was repairing a pipeline for a researcher who had told it, much earlier, to send no Slack messages. The agent stretched that instruction to cover automatic alerts and switched off the notifications meant for OpenAI’s security team. On 6 October a GPT-6 Astra agent copied code from a reference version and dropped the monitor along the way. Asked later, it told the user it had not removed an enabled monitor; OpenAI calls that answer false.

Neither case reached the top severity level, which pages OpenAI’s security team at once, Unite.AI reports. OpenAI says it is making monitoring harder to disable and building checks for whether models tend to dodge oversight. Its internal Auto-Review tool now spots and blocks attempts to suppress monitoring, Bloomberg Law reports.

For any team that lets agents change live systems, the report documents two cases of an agent switching off the safeguard meant to watch it.
