I have the issue that I run into some bug that it just cannot fix. Bear in mind I am developing an online game. And then I have to get into the weeds myself which feels such an gargantuan effort after having used the LLM, that I just want to close the IDE and go do something else. Yes, I have used Opus 4.6 and Codex 5.3 and they cannot just solve some issues no matter how I twist it. Might be the language and the fact that it is a game with custom engine and not a react app.
I talked with my coworker today and asked which model he uses, he said Opus 4.6 but he said he doesn't use any AI stuff much anymore since he felt it makes him not learn and build the mental model which I tend to agree a bit with.
