I think this is too simplistic. Codex is increasingly useful for business usage. I use it for both technical stuff and doing non technical things with my inbox, google drive, etc. It's pretty good for that. And it's pretty clear that business users are very much untapped potential at this point. They need proper agents with tunable guard rails and all the rest.
It seems very competent at coding tasks as well. I don't think Anthropic has a huge edge on that front. It's more of a neck and neck race with proponents in both camps. I ignore most benchmarks at this point; I don't think they have much relevance for normal users.
I think it's actually necessary for both to try out different approaches. Nothing is set in stone yet when it comes to the UX of these things.
