Enterprise Custom Large organisations. | |||
| Which plan to pick | Start on Pro. It is enough to build a small site or tool in evenings and weekends. If you hit the limit most days, Max 5x is the next step; it costs five times as much but usually works out cheaper than paying for the API directly. Max also lets you spend up to half your weekly limit on Fable, which Pro only gets through paid credits. | Install the free version and connect a model you already pay for. If you want to code most days without watching an API bill, add ClinePass at $9.99 a month for the open models, and keep a Claude or GPT key for the hard jobs. Enterprise only matters once a company needs JetBrains or central controls. | 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. |
