Five of OpenAI's seven Codex models cannot be bought any more. Their model cards are still online

Read OpenAI's model index today and the Codex line looks like a healthy range of seven coding models. Read the deprecation page and five of them were switched off seven weeks ago. The withdrawal was announced on 22 April 2026 and executed on 23 July 2026, in a batch that also took the chat aliases and the deep research variants. Four Codex models went that day - gpt-5-codex, gpt-5.1-codex, gpt-5.1-codex-max and gpt-5.1-codex-mini - and gpt-5.2-codex, released only in January, went with them. The substitute named for most of them is GPT-5.6 Sol, a general-purpose model rather than a coding one; GPT-5.1-Codex Mini was pointed at GPT-5.6 Terra instead. Earlier, on 12 February 2026, OpenAI had already removed codex-mini-latest, the model that started the line in May 2025. That leaves exactly one survivor: GPT-5.3-Codex, released on 24 February 2026. The pricing page confirms it - among all Codex models, gpt-5.3-codex is the only one still quoted with a rate. Everything else in the family is documentation without a product behind it. The documentation has not caught up. The models index still lists all seven with live links, and each card still opens with a present-tense description, a full endpoint table and a price in dollars per million tokens. Nothing on those pages says the model is gone. A developer who starts from the model list - the obvious place to start - has no way of knowing which of these can still be called. There is a second oddity in the same trail. The replacement OpenAI named for codex-mini-latest, gpt-5-codex-mini, has no card at all: the documentation URL returns a redirect and then a 404, and the name does not appear in the model index. The recommended migration target is harder to find than the model it was meant to replace. One more number is worth keeping in view. OpenAI's own policy promises at least six months of notice for generally available models, but only three months for specialised variants - and it names Codex versions as an example. GPT-5.2-Codex lived a little over six months from release to shutdown. In this line, a coding model that is current in January can be gone by summer. We have brought all six retired models into the catalogue with their shutdown dates, so the Codex family can be read as what it is: one model on sale and six in the archive.
