No it wasn't, Fable is a general purpose model for use in regular chat, analysis, as well as coding.
And yes, the parent poster is accurate, Fable is just as prone to moronic mistakes as Opus was. Stop being so AI-pilled.
Codex is still a better model, and yes, for the hardest engineering problems. I use Claude for UI/GUIs and Codex for all my backend, because I have 20 years of experience of actual hard engineering, and I can see that Codex writes, cleaner code, and is far more steerable.
Bad engineers think Claude is better because it writes more lines of code and is more "proactive", but lines of code doesn't make a better system.
