| Which plan to pick | Pro at $20 is the place to start, and it is the only sensible way to try the cloud agent. Watch your quota for the first fortnight, and use cheaper models for routine jobs before deciding whether Max or Teams is worth it. | Pro is the sweet spot for an individual: cheap, unlimited autocomplete and enough credits for a few agent tasks a week. Only move to Pro+ if you find yourself buying extra credits every month. | 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. If you outgrow Plus, Pro starts at $100 and has no five-hour limit for now. The $200 tier gives new subscribers less usage than it used to, and Ultrafast mode is only on the $500 tier. |
