I know that these types of comments are not really popular here, but this struck a chord with me because I feel the same. They aren't remotely close.

I have codex right now purely because they gave me a month free of ChatGPT Pro, so I have been using it in between my usage resets with claude. Since it's "free money" for me I have been using it exclusively on xHigh.

One of my most frequent prompts is "hey codex worked on ____, but it didn't quite hit the mark, can we review the work..."

Yes, part of this is normal even within the same model -- you have the highest power model review the work for correctness, refactoring opportunities, and so on, but man I tell you, I don't know what it is about codex, this is obviously one guy's anecdote -- same prompting style, same repository documentation ala MD files, same skills, way different results.

All that to say, maybe the bug report is on to something here, and it can be fixed.
