OpenAI publishes Codex credit rate card, showing tiered rates for Plus, Pro and Business

OpenAI has published a help-center rate card that spells out how Codex usage is priced across ChatGPT Plus, Pro, Business, Enterprise, Edu, Health and Gov plans. The document, updated five days ago, says Codex now runs under a “flexible pricing structure” and lists plan-specific rates rather than describing the coding agent as a single bundled feature. The same help page says OpenAI changed Codex pricing on April 2, 2026, moving from per-message billing to pricing aligned with API token usage for new and existing Plus, Pro, and ChatGPT Business customers, as well as new ChatGPT Enterprise plans. OpenAI said it extended that update on April 23 to all existing Enterprise plans, including Edu, Health, Gov and ChatGPT for Teachers. (help.openai.com) That matters because OpenAI is now showing customers, in one place, that Codex usage is metered differently by plan type and billed through credits rather than treated as one flat subscription entitlement. The company’s related billing pages say credits can be purchased for additional usage and tracked through usage dashboards and workspace billing tools. (help.openai.com) ### When did OpenAI change how Codex is billed? OpenAI said April 2, 2026 was the date it shifted Codex pricing to token-based billing for Plus, Pro, Business and new Enterprise customers. The help article describes that move as replacing the earlier per-message model with pricing “aligned with API token usage.” April 23, 2026 was the second date in the rollout. (help.openai.com) OpenAI said that was when all existing ChatGPT Enterprise plans were moved to the same model, including Edu, Health, Gov and ChatGPT for Teachers. A “small subset” of Enterprise customers remains on a legacy rate card and is told to contact OpenAI sales. ### Which plans are covered by the published rate card? (help.openai.com) The Codex rate card says it applies to new and existing ChatGPT Plus and Pro customers, new and existing ChatGPT Business customers, and new and existing Enterprise, Edu, Gov, Health and ChatGPT for Teachers customers. The page groups those customers under a token-based pricing schedule. OpenAI’s broader help documentation also separates consumer and workspace billing paths. (help.openai.com) The Plus and Pro credits article says credits currently can be used with Codex for Plus and Pro subscribers, while Business and Enterprise/Edu plans are covered by workspace-level flexible pricing and shared credit pools. ### What does the new documentation show about how OpenAI is packaging Codex? The help article says Codex credit rates “work across Plus, Pro, Business, Enterprise, Edu, Health, and Gov plans,” which makes the plan segmentation explicit in OpenAI’s own billing language. The page also says the current rate card is part of a “flexible pricing structure,” tying Codex usage to credits and token consumption. (help.openai.com) ChatGPT Business documentation adds another layer of separation. OpenAI says Business is built around two seat types — standard ChatGPT seats and Codex seats — and that Business billing covers both seat charges and usage-based Codex costs. ### Where can customers monitor usage and spending? OpenAI’s consumer billing page says Plus and Pro users can buy credits when they reach included limits and view balances in the Codex Settings usage dashboard on the ChatGPT web app. (help.openai.com) The same page says those credits are flexible across supported features, including Codex for Plus and Pro users. (help.openai.com) Workspace customers get separate controls. OpenAI’s Business billing help says workspace owners can manage credits, auto-top-up and usage analytics from workspace billing settings, and a separate spend-controls article says Enterprise and Edu plans can set usage limits across teams and roles to prevent overspend. ### What should customers watch next? OpenAI’s help pages point customers to the Codex rate card for current pricing and to plan-specific billing pages for how credits are purchased and governed. (help.openai.com) The Codex article says some Enterprise customers still use a legacy rate card, with questions directed to OpenAI sales. May 2026 billing changes are still flowing through adjacent ChatGPT products. (help.openai.com) OpenAI’s Business billing page says the lower standard-seat price introduced on April 2 will appear on the next monthly bill or annual renewal, while Codex usage continues under the published token-based rate card.
