Codex 额度用完后的四条路：credits、买即时重置、重置卡、Luna Reserve
作者 vortwang更新于
Codex 撞限之后有四样东西能让你继续，但不能互相替代。credits 按量付费，计划额度用完后才扣；购买的即时重置在结账成功那一刻恢复 5 小时与周额度，并改变周重置日程；重置卡是存在账号里、用掉或过期为止的一次性重置；Luna Reserve 按官方说法是「兜底模式，不是需要购买的独立模型」。价格只在结账页显示。
官方文档怎么说
Your plan's included usage is used first. After you hit plan limits, usage draws from your credit balance.

怎么算
credits 和重置回答的是不同的问题。credits：「Your plan's included usage is used first. After you hit plan limits, usage draws from your credit balance.」在「Codex Settings > Usage > Credits」（网页与 Codex 应用）购买，「valid for 12 months from purchase」，不碰你的窗口。购买的即时重置正相反：它「pulls your normal weekly allowance forward rather than adding a separate usage entitlement」，立即生效，「cannot be saved for later」，并把下一次自动周重置设在「7 days after that first request」。购买重置只对「eligible ChatGPT Plus and Pro personal accounts」开放；「It is not available on Free, Go, Business, Enterprise, or Edu plans.」
重置卡是免费的那一种。它存在账号里，「must be applied by you」，并且「is consumed only when it successfully refreshes at least one eligible usage window」。在 Settings → Usage 或 CLI 的 /usage（「View account token usage or use a rate-limit reset」）兑换。它会过期：「Once an unused reset expires, it cannot be restored or reissued.」重置卡「are promotional benefits」，而且「Future resets are not guaranteed.」
Luna Reserve 根本不是重置。它「gives selected accounts additional usage with GPT-5.6 Luna after regular usage is exhausted」，只对「selected personal ChatGPT Plus and Pro accounts」开放，并且「doesn't restore regular usage or unlock our most capable models」。留意用量警告里的「a moon indicator」。有用户报告 Codex CLI 用不上它（issue #40939）；帮助中心点名的是桌面应用和网页。本页引用的帮助中心页面都没有公布重置或 credits 的价格；价格只在结账时显示，本站不转述第三方数字。
| 问题 | credits | 购买的即时重置 | 重置卡 | Luna Reserve | 来源 |
|---|---|---|---|---|---|
| 什么时候起作用？ | 计划额度用完之后；包含额度先用 | 结账成功那一刻，「even if you still have usage remaining」 | 你兑换时；只有真的刷新了至少一个窗口才被消耗 | 常规额度用完之后，仅限被选中的账号 | [1] [2] [3] [4] |
| 在哪里买或兑换？ | Codex Settings > Usage > Credits（网页与应用）；可选自动充值 | 桌面 Usage 设置里的「Buy an instant reset」，或周限额横幅 | Settings → Usage，或 CLI 里 /usage | 不用买：用量警告里出现提示或月亮图标 | [1] [2] [3] [4] [7] |
| 会改变周重置日期吗？ | 不会 | 会：下一次自动重置在你第一次请求之后的第 7 天 | 会：「changes your weekly reset date」 | 不会；常规额度仍然是用完状态 | [2] [3] [4] |
| 会恢复常规额度吗？ | 不会；它为超出上限的用量付费 | 会：5 小时与周两个窗口 | 会：两个窗口（完整重置） | 不会：「doesn't restore regular usage or unlock our most capable models」 | [1] [2] [3] [4] |
| 谁有资格？ | Plus 与 Pro（Codex）；不用换计划 | 「eligible ChatGPT Plus and Pro personal accounts」；Free、Go、Business、Enterprise、Edu 不行 | 活动点名的账号；「Future resets are not guaranteed」 | 「selected personal ChatGPT Plus and Pro accounts」；Business、Enterprise 不行 | [1] [2] [3] [4] |

| 价格 | 帮助页未公布；费率卡按每 token 的 credits 计 | 未公布；「Review the price and payment method in checkout」 | 免费（促销发放） | 符合条件的账号免费 | [1] [2] [3] [4] [6] |
常见问题
我有 credits，会先扣 credits 还是先用重置卡？
计划额度用完后 credits 会自动扣：「After you hit plan limits, usage draws from your credit balance.」重置卡从不自动生效，它「must be applied by you」。所以两者都在账号里时，一过上限 credits 就开始扣，除非你先把重置卡兑换掉。
购买的即时重置和重置卡是一回事吗？
不是。帮助中心说即时重置「does not add to your credit balance or give you a banked reset to use later」，而且「cannot be banked or scheduled for later」。重置卡等你兑换；购买的重置在结账时生效，并改变你的周重置日程。
Codex 即时重置或 credits 多少钱？
本页引用的帮助中心页面都没有公布。说明写的是「Review the price and payment method in checkout」；credits 费率卡按每 token 的 credits 计，不是按包标美元价。以你自己账号显示的价格为准，本站不转述第三方数字。
出现 Luna Reserve 是不是说明我的额度被重置了？
不是。「Luna Reserve is a fallback mode, not a separate model you need to buy. It doesn't restore regular usage or unlock our most capable models.」你的常规窗口仍然是用完状态，直到它们到点或你用了重置；Reserve 只是让你在这期间用 GPT-5.6 Luna 继续，而且只对被选中的账号开放。
