OpenAI shifts pricing and models
OpenAI introduced a $100 ChatGPT Pro tier aimed at heavy developer users and higher Codex access for code tasks. The company also adjusted which models appear in the ChatGPT consumer interface while keeping API access separate, with documentation noting retirements and availability differences for certain GPT-4x variants. Separately, OpenAI urged Mac users to update desktop apps after reports of certificate-targeting attacks, highlighting client-side security steps.

OpenAI has split ChatGPT more sharply by price and product line, adding a new $100-a-month Pro plan for heavier Codex use while trimming older models from the ChatGPT app. (help.openai.com 1) (help.openai.com 2) The new Pro plan costs $100 a month, half the price of the earlier $200 Pro offering, and OpenAI says it includes five times more Codex usage than ChatGPT Plus. Through May 31, OpenAI said those subscribers will get up to 10 times Plus usage on Codex as a launch promotion. (help.openai.com) (9to5mac.com) Codex is OpenAI’s coding agent inside ChatGPT, and the company’s help pages now place it across Plus, Pro, Business, and Enterprise or Edu plans with different limits and, in some cases, credit-based overages. OpenAI also changed Codex billing on April 2 to align with application programming interface token usage instead of per-message pricing for several plans. (help.openai.com 1) (help.openai.com 2) At the same time, OpenAI is narrowing what ordinary ChatGPT users see in the model picker. Help Center pages say 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, while application programming interface access stayed unchanged. (help.openai.com 1) (help.openai.com 2) That distinction matters because OpenAI is treating ChatGPT less like a mirror of its developer platform and more like a curated consumer app. The Codex changelog says the product selector stopped showing several older coding models on April 7, and that ChatGPT sign-in users will lose access to those choices in Codex on April 14 unless they use an application programming interface key or another model provider. (developers.openai.com) (help.openai.com) OpenAI also used the week to push a security message to Mac users after a software supply chain attack hit Axios, a JavaScript library used in one of its macOS signing workflows. In a post published April 10, OpenAI said the compromised workflow had access to a certificate and notarization material used to sign ChatGPT Desktop, Codex, Codex command line interface, and Atlas. (openai.com) (9to5mac.com) OpenAI said it revoked the affected certificate, shipped new signed versions, and urged users to update ChatGPT Desktop to version 1.2026.091 or later, Codex to 0.27.0 or later, and Codex command line interface to 0.20.0 or later. The company said it had no evidence the certificate or notarization material was exfiltrated, but it treated the incident as a credential compromise and rotated secrets anyway. (openai.com) (9to5mac.com) The result is a cleaner but more segmented OpenAI lineup: cheaper Pro access for people who spend long stretches coding, fewer legacy model choices inside ChatGPT, and separate rules for the developer side. The next test is whether users pay for the extra Codex headroom or move to rivals that still compete on model choice and coding limits. (help.openai.com) (developers.openai.com)
