OpenAI 为 12 月设定 ChatGPT 与 Codex 共享用量额度
OpenAI Sets Shared ChatGPT and Codex Usage Allowance for December
OpenAI 计划在 12 月把 Codex、ChatGPT Work、ChatGPT for Excel 和 Workspace Agents 统一到共享用量与积分池中，ChatGPT for Word 也计入该共享额度。Codex 已包含在各档 ChatGPT 套餐中，Codex Cloud 面向符合条件的 Plus、全部 Pro 档、Business、Enterprise、Healthcare 和 Education 账户开放，用量取决于模型、运行位置、任务复杂度、上下文、推理、速度和工具，长任务消耗明显更多。Codex 限额按五小时和每周两个窗口计算，Business 的 Premium 席位没有五小时限制，Standard 席位在 GPT-6.1 Sol 或 GPT-6 Sol 上每五小时约 15–150 条消息。

What the Change Consolidates
OpenAI already meters much of this activity from shared pools. On plans that use shared allowances or credits, Codex, ChatGPT Work, ChatGPT for Excel, and Workspace Agents draw from a shared allowance and credit pool, per OpenAI’s Codex documentation. ChatGPT for Word also draws from the shared usage allowance for Codex and other premium features, according to the company’s release notes.
Codex itself is included across ChatGPT plans, including Free and Go. Codex Cloud, which runs coding tasks on OpenAI-managed computers, is available to eligible Plus, all Pro tiers, Business, Enterprise, Healthcare, and Education accounts. The documentation states that consumption depends on the model, where a task runs, task complexity, context, reasoning, speed, and tools, and that a long-running task can use substantially more allowance than a short request. Codex limits run on five-hour and weekly windows, and using a full banked reset refreshes both windows while changing the weekly reset date. OpenAI Support does not reset ChatGPT or Codex usage limits.
ChatGPT Business bundles ChatGPT, Work, and Codex and is sold in Standard and Premium seats. OpenAI’s plan documentation states that Premium seats include more Work and Codex usage and carry no five-hour usage limit, while Standard seats operate with per-model local-message estimates per five-hour window: for example, 15–150 messages on GPT-6.1 Sol or GPT-6 Sol and 250–2,000 on GPT-5.6 Luna, with actual usage varying by model and task. Pro-model chat allowances remain separate from Work and Codex usage: Business Standard includes 15 Pro messages per month and Business Premium 50 per week, shared across GPT-6 Pro and GPT-5.6 Sol Pro. The documentation describes Instant chat as virtually unlimited, subject to anti-misuse safeguards under OpenAI’s Services Agreement.
Recent Adjustments to the Same Pools
OpenAI said it is preparing carefully for the December transition to help prevent disruption to user workflows, and that it expects most users will not need to wait for their usage to reset more often than they do now.
