In my experience gpt5-codex (medium) and codex-cli is notably better than Sonnet 4.5 and claude-code. (note: never tried Opus)

It is slower, but the results are much more often correct and it doesn't rush into half-baked solutions/dumb approaches as eagerly.

I'd much rather wait 5 minutes than have to clean up manually or try to coax a model into doing things differently.

I also wouldn't be surprised if the slowness was partially due to OpenAI being quite resource constrained. They are repeatedly complaining about not having sufficient compute.

Bigger picture: I think all the AI coding environments are incredibly immature. There are many improvements to be unlocked.

Notice how pricing is the top discussion theme. People love free shit and it's hard to deny codex usage limits are more generous. My 2c for someone who uses both tools pretty consistently in an enterprise context:

- Codex-medium is better if you have a well articulated plan you "merely" need to execute on, need help finding a bug, have some specific complex piece of logic you need to tweak, truly need a ton of long range context to reason about an issue. It's great and usage limits are very generous!

- Sonnet 4.5 is better for everything else. That means for me: non-coding CLI ops, git ops, writing code with it as a pair programmer, OOD tasks, big new chunks of functionality that are highly conceptual, architectural discussion, etc. I generally approve every edit and often interrupt it. The fast iteration and feedback is key.

I probably use CC 80% of the time with Codex the other 20%. My company pays for CC and I don't even look at the cost. Most of my coworkers use CC over Codex. We do find the Codex PR reviewer to be the best of any tool out there.

Codex gets a lot of play on twitter also because a lot of the most prolific voices there are solo devs who are "building in public". A greenfield, solo project is the ideal (only?) use case for running 5 agents in parallel or whatever. Codex is probably amazing at that. But it's not practical for building in enterprise contexts IMO.

For larger tasks that I know are parallelizable, I just tell Claude to figure out which steps can be parallelized and then have it go nuts with sub-agents. I’ve had pretty good success with that.

They are similar enough that using one over the other is at most a small mistake. I prefer Claude models (perhaps I'm more used to them?) but Codex is also very good.

Totally agree. A lot of it is simply personal preference at this point.

That’s falsifiable quite easily by measuring tokens per second.

Rather, the real reason codex takes longer is that it does more work to read more context.

IMO the results are much better with codex, not even close
