Codex rate card goes live, detailing credits per action across Plus and other tiers

OpenAI published a Codex rate card in its Help Center on May 13, 2026, giving customers a detailed table for how coding usage is charged across ChatGPT Plus, Pro, Business, Enterprise, Edu, Health and Gov plans. The document sets credit consumption by token type rather than by message, and it applies to both new and existing users on most listed tiers. The Help Center article says OpenAI changed Codex pricing on April 2, 2026, to align with API token usage for Plus, Pro, Business and new Enterprise plans, then extended that update on April 23 to all existing Enterprise plans, including Edu, Health, Gov and ChatGPT for Teachers. A small subset of Enterprise customers remains on a legacy rate card, according to the article. (help.openai.com) The move comes as OpenAI is also pushing new adoption offers around Codex. OpenAI’s enterprise promotion page says eligible enterprise customers can request two months of free Codex usage for net-new users during a limited-time offer running for the next 30 days. ### What exactly did OpenAI publish on May 13? The May 13 Help Center posting is a rate card that spells out credits per 1 million input tokens, cached input tokens and output tokens for several Codex models. (help.openai.com) OpenAI says the format replaces “average per-message estimates” with a direct mapping to token use, giving customers a clearer view of how tasks consume credits. (openai.com) The published table lists GPT-5.5 at 125 credits per million input tokens, 12.50 credits per million cached input tokens and 750 credits per million output tokens. GPT-5.4 is listed at 62.50, 6.250 and 375 credits respectively, while GPT-5.4-Mini is listed at 18.75, 1.875 and 113 credits. GPT-5.3-Codex and GPT-5.2 are each listed at 43.75 credits per million input tokens, 4.375 cached and 350 output. (help.openai.com) ### How does the new system differ from the old one? OpenAI says the pricing change took effect on April 2 for several plans and replaced per-message pricing with token-based pricing. Under the new system, usage depends on the mix of input, cached input and output tokens in each task rather than a simpler message estimate. The Help Center article also notes that “Fast mode” consumes credits at a higher rate for supported models. (help.openai.com) Code review uses GPT-5.3-Codex, while GPT-5.3-Codex-Spark is listed as a research preview with rates that are “not final.” ### Which plans and products does the rate card cover? OpenAI’s Help Center says the token-based rate card 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. (help.openai.com) The company’s developer pricing page separately lists Codex as included in Free, Go, Plus, Pro, Business, Edu and Enterprise plans, with different usage limits and features by tier. The developer pricing page lists Plus at $20 per month and Pro starting at $100 per month. It says Pro customers can get higher Codex usage than Plus, and that the $100-per-month Pro tier has doubled normal Codex usage until May 31, 2026. ### What other Codex incentives is OpenAI running now? OpenAI’s enterprise promotion page says eligible enterprise accounts can get two months of free Codex usage for net-new users if they apply during the current 30-day window. (help.openai.com) The page is framed as a limited-time promotion for organizations adding new Codex users. A separate Help Center article says ChatGPT Business workspaces can earn $100 in promotional credits for each new eligible Codex seat that sends its first Codex message, up to $500 per workspace. (developers.openai.com) That promotion began April 2, 2026, and the credits expire on April 30, according to the terms page. ### What does OpenAI say Codex typically costs? (openai.com) OpenAI says in the Help Center rate card that Codex costs about $100 to $200 per developer per month on average, with wide variation depending on model choice, the number of running instances, automations and use of fast mode. The company also says users can monitor remaining credit, purchase more credit and manage auto-reload settings in the Codex usage panel. (help.openai.com) OpenAI launched Codex as a research preview in May 2025 and later expanded access to Plus users in June 2025. The current pricing and promotions pages now give customers a more explicit set of rates and plan terms as the company continues to sell Codex across individual, business and enterprise tiers. The next near-term dates are already on OpenAI’s pages. The Pro usage promotion runs through May 31, 2026, the enterprise free-usage offer is open for the next 30 days, and the Business Codex credit promotion remains governed by the published Help Center terms.
