Which plan to pickSkip Plus unless you are happy with Grok. Premium is the realistic starting point if you want Claude or OpenAI models, and budget for the extra usage billing on top of the $30. There is also a $200 Ultra plan with 50x the Plus usage for people who live in it.Start on the free Individual tier; it is the whole point. If you hit the weekly limits and you also use Gemini for other things, Google AI Pro at $19.99 is a sensible step. Ultra only makes sense for full-time developers.If you already have ChatGPT Plus, you have Codex: just try it. If you are choosing between this and Claude Code with no existing subscription, Plus at $20 and Claude Pro at $20 cost the same, so pick whichever chat assistant you prefer.
