OpenAI narrows enterprise rollouts

OpenAI is still limiting Custom Actions inside GPTs by plan, while separately moving Codex pricing onto a token-style meter for more customers. (help.openai.com 1) (help.openai.com 2) GPTs are custom versions of ChatGPT that can be set up with instructions, files, tools and outside connections. OpenAI’s help center says those outside connections can be added through “actions,” which let a GPT call external application programming interfaces, or APIs. (help.openai.com) In OpenAI’s ChatGPT release notes, the company said GPTs with Custom Actions currently support GPT-4o and GPT-4.1 on the web for Plus, Pro and Team users, while Enterprise and Education availability is listed as “coming soon.” The same release-notes page was updated in April 2026. (help.openai.com) That leaves OpenAI’s biggest managed workplace customers in a staggered rollout even as the company keeps expanding GPT controls elsewhere. A separate Enterprise and Education release-notes page says those users can now choose from the full set of ChatGPT models when building Custom GPTs, showing that model choice and Custom Actions have not moved in lockstep. (help.openai.com) OpenAI also published a Codex rate card that changed how usage is measured for many paying customers. The company said on April 2, 2026 that new and existing Plus, Pro and ChatGPT Business customers, plus new Enterprise customers, now use token-based pricing instead of per-message pricing. (help.openai.com) Under that new Codex card, OpenAI lists prices per 1 million tokens, with separate rates for input, cached input and output. The page says GPT-5.4 costs 62.50 credits for input and 375 credits for output per 1 million tokens, while GPT-5.1-Codex-mini costs 6.25 credits for input and 50 credits for output; fast mode uses twice as many credits. (help.openai.com) OpenAI kept a second, older Codex price sheet in place for other accounts. The company said existing Enterprise and Education customers, along with new and existing Education, Teacher and Healthcare plans, should stay on the legacy rate card until migration happens “in the upcoming weeks.” (help.openai.com) The credit system also reaches beyond coding. OpenAI says credits in ChatGPT can be bought as a pay-as-you-go add-on, and that the same balance currently works across Codex for Plus and Pro subscribers and Sora for all users. (help.openai.com) OpenAI’s own documentation now shows two separate transitions happening at once: Custom Actions are not yet fully rolled out to Enterprise and Education, and Codex billing is not yet fully migrated for those same larger accounts. For customers trying to standardize internal tools, the practical answer is still plan-by-plan. (help.openai.com 1) (help.openai.com 2)
