Someone was asking the same on a Telegram channel I'm on, so yes.

Personally, I'm currently using a free trial of Codex, and I'll just quote what I wrote on that channel:

  I have some stupid with Codex and GPT-5.4, FWIW, even on extra high.

  Like, I tell it to "use TDD" and then I find more than zero of the tests open the source code and do a regex to confirm only the existence of substrings within the source code, which obviously misses all questions of functionality

Haven't we moved past using derogatory and offensive words like the one in the title?
