At least Anthropic have a max subscription for corporate. Codex is only pay-as-you-go pricing beyond the base plan. Hence I'm stuck with Opus for work for the foreseeable future.
Codex only gets billed at API prices. The normal seats are more like a normal subscription, but their codex limits were LESS than a $20 subscription last time I checked (it used to be the same or more but they reduced it when they introduced the codex only seats).
I don't think so, I'm on a ~$200 subscription (guessing that counts as way beyond "base plan") and have no pay-as-you-go pricing at all, using the OpenAI APIs would be way too expensive for me.
You can't use sub pricing with orgs w/ OpenAI.
