Yet all the people OpenAI bought out recently say Codex is “the future”
I've used/use both, and find them pretty comparable, as far as the actual model backing the tool. That wasn't the case 9 months ago, but the world changes quickly.
I did notice that codex - like Claude - is now better about auto delegating to agents for keeping the context focused and agents in parallel.
None of them are particularly sticky - you can move between them with relative ease in vscode for instance.
I think the only moat is going to be based on capacity, but even that isnt going to last long as the products are moved away from the cloud and closer your end devices.
