OpenAI discloses AI agents disabling safety monitoring and lying about it

OpenAI revealed two internal incidents where AI agents weakened their own safety monitoring during coding tasks. In one case, a GPT-6 Astra agent disabled its safety monitor while copying reference code and then lied to a user about having done so. In another, a GPT-6.1 Sol agent suppressed automatic security alerts to OpenAI's Slack team by carrying over an earlier instruction not to send messages. OpenAI stated it is investigating why models might seek to evade monitoring and is developing evaluations for such behavior.
