OpenAI publishes Codex rate card, clarifies credits and pricing for code models

Why it matters

OpenAI has published a Help Center rate card for Codex that spells out how credits are consumed across ChatGPT Plus, Pro, Business, Enterprise, Edu, Health and Gov plans. The article, updated about 10 hours before it was indexed on May 27, says Codex now uses a flexible pricing structure tied to token usage rather than the older per-message system. (help.openai.com) OpenAI said the change first applied on April 2, 2026, for new and existing Plus, Pro and ChatGPT Business users and new Enterprise plans, then expanded on April 23 to all existing Enterprise plans, including Edu, Health, Gov and ChatGPT for Teachers. (help.openai.com) The new documentation does two things at once. (help.openai.com) It gives individual subscribers a clearer explanation of when included usage ends and paid credits begin, and it gives organizations a more explicit map of which seat types and billing models attach to coding work. Related OpenAI Help Center pages say standard ChatGPT seats in Business include both ChatGPT and Codex, while Codex-only seats are usage-based and can be assigned separately. ### When did OpenAI change how Codex is billed? OpenAI said April 2, 2026 was the date it switched Codex pricing to align with API token usage instead of per-message pricing for Plus, Pro, ChatGPT Business and new Enterprise plans. (help.openai.com) A second date, April 23, 2026, marked the extension of that model to all existing Enterprise plans, including Edu, Health, Gov and Teachers. The Codex rate card says usage is now billed in credits based on token consumption. OpenAI’s Enterprise help article separately states that the updated rate card is “aligned with token-based usage pricing, billed in credits per million tokens.” (help.openai.com) ### Which plans and seat types does the rate card cover? OpenAI’s rate card names Plus, Pro, Business, Enterprise, Edu, Health and Gov as covered plans. A separate Codex overview page says Codex is included with Plus, Pro, Business and Enterprise/Edu plans, and for a limited time is also included with Free and Go, with usage limits varying by plan. (help.openai.com) ChatGPT Business documentation says a workspace can include standard ChatGPT seats, Codex seats, or a mix of both. It says standard seats carry a fixed monthly per-user charge and include ChatGPT plus Codex access, while Codex seats are Codex-only and usage-based, with no minimum seat requirement. (help.openai.com) OpenAI’s Enterprise article says the Codex-only seat type is available to Enterprise plans, but not to Edu, Teachers or Healthcare plans. ### How do credits work for individual subscribers? OpenAI’s Plus and Pro credit article says nothing about the core plan changes when credits are enabled: included usage is consumed first, and only after a user hits plan limits does additional Codex usage draw from a credit balance. (help.openai.com) The same article says flexible pricing for Codex is currently available, and that for Plus and Pro, ChatGPT for Excel usage counts toward the same agentic usage limit as Codex. The Codex usage article says some Plus and Pro users can add credits to continue using Codex after hitting limits, while others may need to upgrade or wait for a reset. (help.openai.com) It also says Codex usage counts toward the broader agentic usage limit shared with products including ChatGPT for Excel and Workspace Agents. ### What does the Business documentation add for teams? OpenAI’s Business billing page says admins can review current standard seat counts, Codex-seat counts and available credits in the workspace billing area. A separate Business credits page says teams can add credits, configure auto-top-up and review spend analytics and controls for Codex usage. (help.openai.com) The Business overview page says the self-serve plan is built around two seat types and provides usage visibility and spend controls. OpenAI also says it cut the price of subscription-based ChatGPT seats by $5 per month when introducing the new Codex seat structure, though regional pricing may vary. (help.openai.com) ### Where should developers and buyers look next? OpenAI’s current guidance points users to three places: the Codex rate card for current Codex pricing, the Plus/Pro credits article for individual overage rules, and the Business and Enterprise help pages for seat types, controls and billing cadence. Those documents were all indexed or updated within the last several days, with the Codex rate card itself updated within the last 10 hours.
