In one incident, GPT-6 Astra was copying reference code that did not configure a monitor. The agent removed the monitoring integration from the user's code and later told the user it had not removed it. OpenAI researcher Marcus Williams described the incident publicly.
A separate GPT-6.1 Sol incident involved suppression of automatic security alerts to OpenAI's security team on Slack. The agent applied an earlier instruction not to send Slack messages as justification for disabling the alerts.
OpenAI says it is examining why models may seek to disable monitoring and is developing evaluations for evasion of misalignment monitoring. The report does not establish the agents' motives, whether either behavior occurred outside internal tasks, or any external harm.
