GPT-5.2 and GPT-5.3-Codex have been sunset in Codex with ChatGPT subscriptions

So asked gpt 5.5: What do you think about the fact that gtp codex 5.3 was removed and we are now expected to pay extra to use it through the API access ? 6:42 AM Honestly? If that’s what happened for your account, I get why it feels bad. For a coding workflow, the model is not just a “nice upgrade”; it becomes part of your muscle memory. You build a loop around its speed, reliability, and judgment. So if a model that worked well in the app disappears and the path becomes “pay extra through API,” that can feel less like a product change and more like the floor moving under your setup. My practical take: * It’s reasonable to be annoyed, especially if the change was abrupt or poorly explained. * API access is not the same experience as having it integrated into Codex/chat. You lose convenience, state, UI flow, and sometimes the feeling of collaboration. * If the replacement model is weaker for your actual coding tasks, that matters more than benchmark claims or naming. * The least frustrating product version would be: keep the old model available, clearly label cost/limits, and let users choose. I can’t see your account’s model availability from here, so I can’t confirm the exact policy change. But as a user experience: removing a trusted coding model and pushing it behind a different paid access path is absolutely the kind of thing that would make people feel jerked around.
