OpenAI publishes Codex rate card

OpenAI has published a more detailed Codex rate card that spells out how coding usage is billed across consumer and enterprise plans, adding a clearer pricing framework for one of its AI coding products. The Help Center page, updated about 11 hours ago, says Codex usage is now priced by API token consumption rather than by average per-message estimates. The page covers Plus, Pro, Business, Enterprise, Edu, Health and Gov plans, while noting that a small subset of Enterprise customers remains on a legacy rate card. OpenAI said the pricing change began on April 2, 2026, and was extended to all existing Enterprise plans, including Edu, Health and Gov, on April 23. ### When did OpenAI switch Codex to token-based pricing? OpenAI said April 2, 2026 was the date it updated Codex pricing to align with API token usage for new and existing Plus, Pro and ChatGPT Business customers, as well as new ChatGPT Enterprise plans. The Help Center page says the same structure was applied on April 23 to all existing ChatGPT Enterprise plans, including Edu, Health, Gov and ChatGPT for Teachers. (help.openai.com) The company said the new format “replaces average per-message estimates with a direct mapping between token usage and credits,” giving customers a more direct view of how input, cached input and output affect credit consumption. That wording appears in the Help Center article that now serves as the rate card. ### What does the rate card actually charge? OpenAI’s published table lists GPT-5.5 at 125 credits per 1 million input tokens, 12.50 credits per 1 million cached input tokens and 750 credits per 1 million output tokens. (help.openai.com) GPT-5.4 is listed at 62.50 input credits and 375 output credits per million tokens, while GPT-5.3-Codex is listed at 43.75 input credits and 350 output credits. The page also says fast mode consumes credits at a higher rate for supported models. The Help Center page says code review uses GPT-5.3-Codex, and that GPT-5.3-Codex-Spark is available as a research preview with rates that are “not final.” OpenAI also says average Codex usage runs about $100 to $200 per developer per month, with variance depending on model choice, automations, fast mode and the number of instances running. ### How does this fit with OpenAI’s team and enterprise packaging? (help.openai.com) OpenAI said on April 2 that ChatGPT Business and Enterprise customers could add Codex-only seats with pay-as-you-go pricing, giving access to Codex without a fixed seat fee. In the same announcement, the company said Codex-only seats have no rate limits and that usage is billed on token consumption. (help.openai.com) That announcement also said OpenAI lowered the annual price of ChatGPT Business from $25 to $20 per seat and offered eligible Business workspaces $100 in credits for each new Codex-only team member, up to $500 per team, for a limited time. OpenAI said more than 9 million paying business users rely on ChatGPT for work, more than 2 million builders use Codex every week, and the number of Codex users inside ChatGPT Business and Enterprise has grown sixfold since January. (openai.com) ### What does OpenAI say about how credits work inside organizations? OpenAI’s flexible pricing documentation says ChatGPT Business and Enterprise plans now have two seat types: a standard ChatGPT seat and a Codex-only seat. The Help Center says those Codex-only seats are available only to ChatGPT Business and ChatGPT Enterprise, not to Edu, Teachers or Healthcare plans. (openai.com) The same document says Business users receive per-seat limits for advanced features and can draw from a shared pool if the workspace has purchased credits. Enterprise and Edu workspaces, OpenAI says, purchase a shared credit pool at the contract level, and advanced features pause when that pool is exhausted unless owners enable overages or buy additional credits through their OpenAI account team.

OpenAI’s developer pricing page lists Codex as included in ChatGPT Free, Go, Plus, Pro, Business, Edu and Enterprise plans, with Plus priced at $20 a month and Pro starting at $100 a month. The same page says Business is offered on a pay-as-you-go basis and notes that Pro users have a temporary usage promotion running until May 31, 2026. (help.openai.com) The current rate card remains posted in OpenAI’s Help Center, and the company’s team-pricing announcement says ChatGPT Business and Enterprise customers can add Codex-only seats now.
