And yet I(and many others publicly on x) chucked Claude for codex back in June. Codex is my workhorse. The main reason I use codex is because of its language. I just got really tired of reading long weirdly worded prose that I had to fix with some skill(though some people like matt pocock and dex horothy have good ideas on this, buts it's just wasteful). This is triply bad for learning newer stuff because it goes up and down the abstraction layer on any topic like mad. One moment it would be explaining a high level detail and then cite contrasts and then point indirectly to an implementation detail as an example. It's idea of explaining more abstractly was also weird in a different way.
Fable was better but I don't have 1000$/day to spend on it.
