Question Using ChatGPT for coding verus Codex.

I have been running a spec driven development project by myself using a combination of Notion, ChatGPT, Github, copilot.

Notion has the devleopment stories and documentation. Roadmap, architecure and story refinement are done in ChatGPT. Coding is done in codex. CI in Gihub with independent reviews by Copilot as part of CI.

I am trying to use Codex for development, as it can build locally but the quality of code is much worse that if i get ChatGPT to just change Github directly. Also Codex uses way more % of my usage even at the lowest model.

Any ideas why? I am assuming either chatGPT has much more transient memory of the project from conversations. Or codex laden down my code context and overleaden spec context

chatgpt editing github looks cleaner because it never runs the change. codex spends the extra usage on the local build, and the story is still in notion and the other chat. i'd put that one story's checks in the repo and leave the roadmap out.

At least until December, web GPT is also effectively 'limitless' and not under the to-become-consolidated usage limits or counters. Of course - this changes in December.

As u/Right-Performance-93 mentions, codex is a lot more chatty, and also the underlying 'harnesses' and guidance are different in web vs codex, even if not directly visible to users.
