Not possible. GPT-5.1 didn’t exist a month ago. I helped train it.

Double checked when the model started getting worse, and realized I was exaggerating a little bit on the timeframe. November 5th is when it got worse for me. (1 week in AI feels like a month..)

Was there a (hidden) rollout for people using GPT-5-thinking? If not, I have been entirely mistaken.
