Codex/Q/On ChatGPT Enterprise and Edu, does Codex usage draw down the monthly allowance before the weekly limits?

• On ChatGPT/Enterprise and Edu, does Codex usage draw down the monthly allowance before the weekly limits?

  • My Answer

    • Hypothesis: Codex now burns the monthly allowance first (for example, pooled workspace credits), then the weekly allowance, which resets each week.
    • Recollection: Earlier the order was the reverse: weekly usage first, then the monthly allotment. I suspect OpenAI reversed it recently, but I'm not sure.

  • AI Answer

    • Short answer: The docs don't support the hypothesis, and they don't record a reversal. No OpenAI page I found describes an Enterprise or Edu account that draws a monthly pool first and a weekly allowance second. The only documented order runs the other way: included plan limits first, then credits. What did change in 2026 is the admin control: per-user weekly limits are being replaced by monthly limits. That is a swap of one cap for another, not a reordering.
    • What the docs say
      • Answer/Official from Codex pricing (formerly developers.openai.com/codex/pricing):
        • Enterprise and Edu workspaces with flexible pricing have no fixed rate limits; "usage scales with credits." There is no 5-hour or weekly allowance to burn before the pool.
        • Enterprise and Edu workspaces without flexible pricing get "the same per-seat usage limits as Plus for most features", which means the 5-hour and weekly windows.
        • Across plans, included limits are consumed first, and credits let work continue once those are reached.
      • Answer/Official from Flexible pricing for the Enterprise, Edu, and Business plans: Enterprise and Edu buy a shared credit pool at the contract level. There are no per-seat caps by default; admins set spend controls by group with RBAC.
      • Answer/Official from Manage usage limits and overages in ChatGPT Enterprise and Edu (help article 20001001):
        • Admins set monthly credit limits as a workspace default, group defaults, and user overrides. The precedence is user override, then the highest group default, then the workspace default.
        • The monthly window is the UTC calendar month by default, or it can be aligned to the billing cycle.
        • The older weekly limits under Permissions & roles stay in force until they are migrated, either with a Migrate button or automatically.
        • The article says Usage limits arrive starting June 18, 2026. Its versions give conflicting automatic migration dates (July 15 in one, August 15 in another). A later version moves the pane to the Global Admin Console as of July 23 and advises against assuming any automatic date.
      • Answer/Official from ChatGPT Work usage and cost and the ChatGPT Work admin FAQ:
        • Work and Codex "share pricing, credits, and usage limits".
        • A user's limit can stop that user before the shared pool runs out.
        • When the pool is empty, the overage setting decides whether usage continues.
        • Neither page mentions weekly limits or an order of consumption.
    • Changelog entries on usage display (ChatGPT & Codex changelog)
      • 2025-11-24, "Usage and credits fixes" (November 2025): all usage dashboards switched to "limits remaining", where the CLI had shown "limits used". This changed how usage is displayed, not the order in which it is consumed.
      • Codex app 26.609 (2026-06-11): rate-limit reset banking for Plus and Pro, and usage-limit errors that show reset timing.
      • Codex app 26.707 (2026-07-09): Codex joined the ChatGPT desktop app on macOS and Windows.
      • Codex CLI 0.144.0 (2026-07-09): usage-limit reset credits show their type and expiration.
      • ChatGPT for iOS 1.2026.267 (2026-10-02): Home Screen and Lock Screen widgets for remaining usage and reset times.
      • ChatGPT for iOS 1.2026.279 (2026-10-13): "Usage widgets adapt to accounts with only a weekly limit."
      • ChatGPT for iOS 1.2026.286 (2026-10-22): usage-limit explanations and reset times appear in the chat.
      • None of these entries says which pool is drawn first, and none mentions an Enterprise or Edu change in consumption order. I found no ChatGPT desktop release note that ties a version to a change in limit order.
    • Inference, not documented
      • The weekly-first, then-monthly order in the recollection above matches the documented order for seats that have Plus-style limits: the weekly and 5-hour windows are spent first, then workspace credits. That is how Business works, and how Enterprise and Edu work without flexible pricing.
      • The sense that the order reversed probably comes from the 2026 migration of admin caps from weekly to monthly. On a flexible-pricing Enterprise or Edu workspace, after migration, a user has one monthly cap drawing on the shared pool, with no weekly allowance behind it.
      • To check a specific workspace, compare what Settings → Usage & billing in ChatGPT Desktop shows (a monthly allowance, a weekly limit, or both) with /status in Codex CLI.
    • Not verified
      • The help article details above come from indexed copies of the article, and those copies disagree on migration dates.
      • The changelog page only rendered October 2026 in full. The 2025-11-24, 26.609, 26.707 and 0.144.0 entries come from search results on learn.chatgpt.com, not from reading the full entries.
