OpenAI segments enterprise stack
- OpenAI’s help docs now separate ChatGPT Business from Enterprise and Edu, with distinct model-limit pages and a new flexible pricing system. - Enterprise plans added a Codex-only seat on April 2, while GPT-5.5 rolled into ChatGPT on April 23 and GPT-5.3 remains available. - The split moves workplace AI toward seat design, usage billing, and admin controls, not one shared chatbot tier.

OpenAI has started splitting its workplace ChatGPT lineup into separate Business, Enterprise, and Edu tracks, with different model menus, limits, and pricing rules. (help.openai.com 1) (help.openai.com 2) The clearest sign is in OpenAI’s own help center: Business now has its own “Models & Limits” page, while Enterprise and Edu share another. Both pages say API access remains unchanged even as ChatGPT access changes by plan. (help.openai.com 1) (help.openai.com 2) OpenAI also added flexible pricing across Business, Enterprise, and Edu plans, and said on April 2, 2026 that Business and Enterprise gained two seat types: a standard ChatGPT seat and a Codex-only seat. Edu was not included in that seat-type change. (help.openai.com 1) (help.openai.com 2) That is a change from the earlier pitch of ChatGPT at work as one premium product with broad access. OpenAI’s current documentation treats workplace AI more like software procurement, with model access, fallback behavior, and billing all separated by organization type. (openai.com) (help.openai.com) The model stack has shifted at the same time. OpenAI’s release notes say GPT-5.5 began rolling out in ChatGPT on April 23, 2026, and the company’s model notes say GPT-5.1 models were retired from ChatGPT on March 11, 2026 in favor of GPT-5.3 Instant, GPT-5.4 Thinking, and GPT-5.4 Pro. (help.openai.com) (help.openai.com) OpenAI’s Enterprise and Edu release notes show the same pattern inside managed workspaces. GPT-5.1 Instant went live in the model picker there, then OpenAI later said GPT-5.3 Instant Mini replaced GPT-5 Instant Mini as the fallback model after users hit GPT-5.3 Instant rate limits. (help.openai.com) The legacy cleanup is broad. OpenAI says GPT-4o, GPT-4.1, GPT-4.1 mini, OpenAI o4-mini, and GPT-5 Instant and Thinking were retired from ChatGPT on February 13, 2026, with GPT-4o lingering in Custom GPTs for Business, Enterprise, and Edu until April 3. (help.openai.com) (help.openai.com) The result is that companies are no longer buying one chatbot with one flagship model. They are choosing a bundle of seats, rate cards, admin rules, and model pathways that can differ between Business, Enterprise, Edu, and Codex-focused users. (help.openai.com) (help.openai.com) OpenAI’s own docs now read less like a consumer product page and more like an enterprise software catalog. The company is still selling models, but it is increasingly packaging them as workplace infrastructure. (openai.com) (help.openai.com)
