| Which plan to pick | Try Pro for a month to see if the agents suit your codebase. If you want Droids working in the background while you do other things, you need Plus. | 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. |
