OpenAI posts Codex rate card detailing prices for Plus, Pro, Business, Enterprise

OpenAI has moved Codex pricing onto a clearer meter. A Help Center article updated this week lays out token-based credit charges for Codex across ChatGPT Plus, Pro, Business, Enterprise, Edu, Health and Gov plans, replacing earlier per-message pricing with rates tied to input, cached input and output tokens. OpenAI said the change first applied on April 2, 2026 for new and existing Plus, Pro and Business users and new Enterprise users, then expanded on April 23, 2026 to existing Enterprise plans, including Edu, Health, Gov and ChatGPT for Teachers. A separate OpenAI product post dated May 14 said Codex is also rolling out in preview inside the ChatGPT mobile app on iOS and Android. The company said the mobile version lets users review outputs, approve commands, change models and start new work while Codex continues running on a connected laptop, Mac mini or managed remote environment. ### What exactly changed in the rate card? (help.openai.com) OpenAI said Codex usage is now priced as credits per 1 million tokens, split across three categories: input tokens, cached input tokens and output tokens. The company said that format “replaces average per-message estimates with a direct mapping between token usage and credits,” giving users a more explicit way to track how context size, caching and generated output affect consumption. (openai.com) The Help Center table lists GPT-5.5 at 125 credits per million input tokens, 12.50 credits for cached input tokens and 750 credits for output tokens. The same table lists GPT-5.4 at 62.50, 6.250 and 375 credits respectively; GPT-5.4-Mini at 18.75, 1.875 and 113; and GPT-5.3-Codex at 43.75, 4.375 and 350. OpenAI said fast mode consumes credits at a higher rate for supported models. (help.openai.com) ### Which ChatGPT plans are covered? The rate card says the token-based pricing 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. OpenAI added that “a small subset” of Enterprise customers should remain on a legacy rate card and directed those customers to contact sales. (help.openai.com) A separate Help Center article updated this week says Codex is included with ChatGPT Plus, Pro, Business and Enterprise/Edu plans. That article also says Codex is available “for a limited time” with ChatGPT Free and Go, and that “all other plans enjoy 2x rate limits.” ### What does OpenAI say Codex typically costs? OpenAI said in the rate-card article that Codex costs “~$100-$200/developer per month” on average. (help.openai.com) The company also said there is “a large variance” depending on the model used, the number of instances running, automations and use of fast mode. The same article says users can monitor remaining credit, purchase credit and manage auto-reload credit from the Usage panel in Codex settings. (help.openai.com) OpenAI’s plan guide separately points users to ChatGPT pricing pages for upgrade options and Codex credit plans for business users. ### What does the mobile rollout add? OpenAI said on May 14 that Codex in the ChatGPT mobile app loads live state from the machine where Codex is operating, including active threads, approvals, plugins and project context. (help.openai.com) The company said updates flow back to the phone in real time, including screenshots, terminal output, diffs, test results and approvals, while files, credentials and permissions remain on the machine running Codex. The ChatGPT release notes say the mobile rollout covers iOS and Android across all plans, including Free and Go, in supported regions. An OpenAI community post said support for connecting the phone to the Codex app on Windows is “coming soon.” (openai.com) ### Where can users check limits and controls? OpenAI’s Codex plan guide says usage limits vary by plan and by the size and complexity of coding tasks. The same guide says Business and Enterprise/Edu admins can control plugin access through workspace app settings and role-based access controls, and that Codex usage is available in the Compliance API for supported clients. (help.openai.com) OpenAI said users who want the latest prices and quotas should check the Codex rate card and related plan pages in the Help Center. The mobile preview is already rolling out, and the company said Windows phone connectivity is the next named step. (help.openai.com 1) (help.openai.com 2)
