In the thread “Codex vs. Claude Code (today)”
Helped: Strict plans for production work; undirected runs for prototyping.
Got in the way: Codex poor at instruction following, goes off plan.
… At the same time it can go on its own pretty far in an undirected way. The result is when I'm doing serious planned work aimed for production PRs, I have to use Claude. When it's experimental and I don't care about quality but speed and distance, such as for prototyping or debugging, codex is great. Edit: I don't think codex being poor at instruction following is inherent, just where they are today
