I just don't find the benchmarks on the site here at all believable. codex for me with gpt-5 is so much better then claude any model version. I mean maybe it's because they compare to gpt-5-codex model but they don't mention is that high, medium, low, etc... so it's just misleading probably... but i must reiterate zero loyalty to any AI vendor. 100% what solves the problem more consistently and of a higher quality and currently gpt-5 high - hands down

It’s so funny to me but ever since they fixed that claud bug my experience has consistently been the exact opposite. Only thing I use codex now for are quite standard things it can solve end to end (like adding new features to my crud app) anything non standard iterating with Claude yields much better results.

Out of curiosity, what kind of work do you use them for? I did a comparison of a few different models for setting up a home server with k3s and a few web apps in nextjs. Claude was my favorite for both tasks, but mainly because it seemed to take my feedback a lot better than others.

Working on a series of applications, from rails, nodejs interfacing with twilio's api's to salesforce api's - also C/C++ libraries. The example that stood out the best to me was implementing fiber support in the http library i maintain for ruby. Initially i prompted claude to implement fiber support. It started to write a few thousand lines of code for what codex rightly identified was to use a different IO selector library. The problem did end up being a bit more complex but gpt-5 overall in my experience has better knowledge of what is really available vs claude which not only ends up writing way more code to solve a problem that requires just knowing the libraries better... all of this is super subjective but my main reason for saying - "I have no loyalty to any AI, just the solution"
