Codex can feel standoffish at times. I can tell very quickly we wont become friends. The personality feels like an employee in another department that while gifted- is merely lending you a slice of their clearly precious time. I get the impression from codex that *gives me the feeling that I am wasting it’s time. That it will help me but deep down- it dos not want to, it does not care if we succeed toether. What I am saying, frinds, is that when I use codex and iterate, I get the impression that Codex does not like me, that deep down it truly does not want to help.

For something I spend all my time using- I’d rather iterate with Claude. The personality makes a big difference to me.

I don't care about "personality" I want quality.

Honestly when I get codex to review the work that Claude does (my own or my coworker's) it consistently finds terrible terrible bugs, usually missing error handling / negative conditions, or full on race conditions in critical paths.

I don't trust code written by Claude in a production environment.

All AI code needs review by human, and often by other AIs, but Opus 4.6 is the worst. It's way too "yeet"

The opus models are for building prototypes, not production software.

GPT 5.4 in codex is also way more efficient with tokens or budget. I can get a lot more done with it.

I don't like giving money to sama, but I hate bugs even more.
