- Update to GPT-5 System Card: GPT-5.2
Evidence & scope
This is a rate, not discrete incidents. OpenAI says it is significantly lower than GPT-5.1 and slightly lower than GPT-5, though the GPT-5 card sampled representative conversations while this card used pre-release A/B test traffic, so comparisons need care. The behavior occurred in real user conversations but crossed no security boundary.
Why it matters
A lower rate is not the problem going away.
