Hello. I recently discovered a problem

What version of Codex is running?

OpenAI Codex (v0.89.0)

What subscription do you have?

pro

Which model were you using?

gpt-5.2-codex xhigh

What platform is your computer?

win10

What terminal emulator and version are you using (if applicable)?

Windows Terminal

What issue are you seeing?

I recently discovered a problem. Last week, I used gpt-5.2-codex xhigh to analyze and locate bugs in my game, fix game jitter, improve game fluency, and so on. The analysis by gpt-5.2-codex xhigh is extremely accurate, almost 100% capable of pinpointing the problem and achieving perfect repairs.However, starting from the past few days, I have noticed that the speed of gpt-5.2-codex xhigh has become significantly faster during my use of codex5.2. Typically, it takes more than 10 attempts to locate the problem. On one occasion, I repeatedly tried to use gpt-5.2-codex xhigh to identify a bug that prevented characters from moving in the game, and it took me 10 attempts before finally locating the real bug. This is a serious waste of time. I would like to know if you have made any modifications to the model in the background or if it has become less intelligent.

What steps can reproduce the bug?
