Codex CLI is pretty good. Codex GUI is fine but I can't get over how it dumbs it down.
IMO, $500 a month is pretty good for most dev work if you select models appropriately for the task (yourself), especially with how token efficient Opus 5.5 medium is. Unfortunately, people with subscription seats can easily get addicted to Fable, higher effort, fast mode, etc.
Could you elaborate on what you mean by dumbs it down? Chalk it up to inertia, but I still love Claude code CLI the best, but when using Codex, I tend to use the app. I don’t know why. No good reason. I’m guessing you mean you get much better results with the CLI?
