It looks the same, but for some reason Claude Code is much more capable. Codex got lost in my source code and hallucinated bunch of stuff, Claude on the same task just went to town, burned money and delivered.
Of course, this is only my experience and codex is still very young. I really hope it becomes as capable as Claude.
Part of it is probably tgat claude is just better at coding than what openai has available. I am considering trying to hack in support for gemini into codex and play around with it.
