When the free quota is insufficient, how much does it cost to pay for it?
| Plan | pricing | Description |
|---|---|---|
| Included in ChatGPT Go | US$8 / mo | Codex Limited Access (Official Website Menu: Go = Codex Limited) |
| Included in ChatGPT Plus | US$20 / mo | Codex complete usage (official website feature list: Plus = Codex Yes, Expanded usage) |
| Included in ChatGPT Pro | US$100 / mo | Codex maximum usage. The official personal plan is currently divided into two tiers: US$100/month = 5 times Plus quota, US$200/month = 20 times Plus quota. [Checked]As of 2026-08-11, upon re-examination, all four official entrances, openai.com/codex/, openai.com/chatgpt/pricing/, chatgpt.com/pricing/, and help.openai.com, returned HTTP 403 (access denied, not 404 not found), and multiple retry paths were still unable to access directly.
