什么是 5 小时窗口?
更新于
5 小时窗口是 Codex 与 Claude Code 按账号计量的短期额度。Codex:上一个窗口结束后你发出第一条消息时新窗口开始;Claude:会话限额每五小时刷新。它在独立的周限额之下,按你自己的时钟刷新,用 /status(Codex)或 /usage(Claude Code)查看。xAI 的 Grok FAQ 只描述了周用量池。
官方文档怎么说
A new window starts when you send your first message in Work or Codex after the previous window ends.

定义
Codex:"Depending on your plan, usage limits may apply over a five-hour window and a weekly window. Where both apply, you need allowance remaining in both to continue"。窗口不是固定时钟:它从上一个窗口结束后你的第一条消息开始,而且 "You may reach the five-hour limit before five hours have passed, even if you still have weekly usage remaining."。定价页公布了各计划的估计值,例如 Plus 每个五小时周期 5–45 条 GPT-6 Astra 本地消息,但它们 "are not fixed message limits"。
Claude Pro 与 Max:"Your session-based usage limit will reset every five hours."。Max 5x 与 20x 的描述是 Pro 每会话额度的 5 倍和 20 倍,没有绝对数字。池子在 claude.ai 与 Claude Code 之间共享,并且 "Usage credits don't affect this reset timing."。Settings > Usage 显示会话已用多少和剩余时间;Anthropic 的页面没有说明时钟从什么开始计。
Codex 的这个窗口关过又开过。2026-07-12 Tibo Sottiaux 宣布 "Temporarily removing the 5 hour usage limit restriction for all Plus, Business and Pro plans"。在时间戳为 2026-08-25 01:16 UTC 的帖子里他写道 "Tomorrow we will bring back the 5h limit for Plus accounts across ChatGPT Work and Codex",据此 Plus 的恢复日期是美国太平洋时间 2026-08-25;同一帖子说接下来几个月 Pro $100 与 Pro $200 保持 "not enabled"。
在出发板上,这个窗口不是被追踪的对象。「上次重置」和「预计下次」描述的是厂商公告的全员重置,状态词「已重置」「重置卡」「预告中」「等待中」「已超期」从不指你自己的窗口。要给自己的窗口倒计时,把 /status 或 /usage 里的时间贴进窗口倒计时工具;计算都在你的浏览器里完成。
在出发板上哪里能看到
出发板的 STATUS 列只用五个词。每一个都是本站按已记录公告计算的固定规则,不是对下一次重置的承诺。
| 状态词 | 含义 |
|---|---|
| 已重置 | 24 小时内有全员官方重置公告。 |
| 重置卡 | 最近信号是可自行兑换的重置卡。 |
| 预告中 | 官方已预告重置,尚未生效。 |
| 等待中 | 常态等待,上次重置后没有新公告。 |
| 已超期 | 距上次重置已超过近期中位间隔的 1.5 倍。 |
常见问题
窗口是从一天里的固定钟点开始的吗?
Codex:不是。"A new window starts when you send your first message in Work or Codex after the previous window ends."。Claude:帮助中心说会话限额 "will reset every five hours",Settings > Usage 显示剩余时间;Anthropic 的页面没有说明时钟从什么开始计。
Codex Pro 还有 5 小时限制吗?
截至 2026-08-25 没有。Tibo Sottiaux:"We are for the upcoming months keeping the 5h limit not enabled for Pro $100 and Pro $200 subscriptions."。Plus 恢复了这个限制;周限额对 Pro 仍然适用。
Grok 有 5 小时窗口吗?
xAI 的 FAQ 描述的是周用量池:"The usage pool limit resets every week on a schedule shown in the Usage tab in Settings."。它没有提到五小时窗口,本站也不替它加一个。
5 小时窗口清空后,周限额会跟着回来吗?
不会。Codex:"Where both apply, you need allowance remaining in both to continue"。Claude:周限额 "applies across all models",按自己固定的每周时间刷新。短窗口清空不会动长窗口。
