| Which plan to pick | 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. | Start with the 14-day trial. Essentials is enough for most small teams; you only pay for developers who open pull requests. Turn on usage-based reviews ($0.25 a file) with a monthly cap if you keep hitting the hourly limit. | 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. |
