What is the expected behavior?

  • Chat displays files codex is editing and when completed, shows all the files it changed and allows you to view changes.

What do you see instead?

I think this bug is only when you use gpt-5-codex I had it yesterday too but I changed today back to the old gpt-5 and I sow the changed files as before. maybe its related to the model

yup, same here, showing diff on gpt-5 but not on gpt-5-codex.
I need it in the new codex model :\

I think this issue has been addressed. If you are still seeing the issue with the latest version of the codex extension, let us know, and I'll reopen.

I have this issue. Using codex in VScode. In the chat window does not show difference nor options to revert changes. I am working with jupyter notebooks with agent mode and GPT-5.1-Codex model
