OpenAI prunes ChatGPT models
OpenAI says GPT‑4o, GPT‑4.1 and several mini variants have been retired from ChatGPT while API access remains unchanged and enterprise Custom GPTs will retain GPT‑4o access. Observers frame the move as platform segmentation—simplifying consumer offerings while preserving enterprise continuity. (help.openai.com) (infobae.com)
OpenAI removed GPT-4o, GPT-4.1, GPT-4.1 mini, OpenAI o4-mini, and GPT-5 Instant and Thinking from ChatGPT on February 13, 2026. (help.openai.com) The change applies to ChatGPT itself, not to the application programming interface that developers use to build software on top of OpenAI models. OpenAI said application programming interface access “remains unchanged.” (openai.com) OpenAI also said ChatGPT Business, Enterprise, and Edu customers could keep GPT-4o inside Custom GPTs until April 3, 2026, even after the consumer-facing retirement took effect in February. Help Center pages for enterprise model access repeated the same cutoff date. (help.openai.com 1) (help.openai.com 2) For users who built custom bots on older models, OpenAI said those GPTs would be moved automatically to the nearest GPT-5.3 Instant or GPT-5.4 Thinking and Pro equivalent. The company said ChatGPT Voice and ChatGPT Images were not changing as part of this update. (help.openai.com) The move narrows the model picker inside ChatGPT while leaving the developer stack more stable. OpenAI’s current Help Center describes GPT-5.3 as the default ChatGPT model and lists GPT-5.4 mini as the lightweight option available across plans with different rate limits. (help.openai.com 1) (help.openai.com 2) That split reflects how OpenAI now sells ChatGPT in layers. Infobae’s April 11 overview of ChatGPT plans described a ladder from Free and Go to Plus, Pro, Business, Enterprise, and Edu, with different caps, tools, and access rules for each tier. (infobae.com) OpenAI said it retired the older ChatGPT models so it could focus on the models “most people use today.” Reporting cited by Infobae said only about 0.1 percent of users were still choosing GPT-4o daily before the cutoff. (openai.com) (infobae.com) Some users still preferred GPT-4o’s style, and OpenAI acknowledged that “losing access to GPT-4o will feel frustrating for some users,” while arguing that fewer model choices would make ChatGPT easier to maintain and update. By April 2026, the company’s own support pages had shifted from preserving GPT-4o in some enterprise corners to documenting its retirement across ChatGPT plans. (openai.com) (help.openai.com)
