Hi @valid tiger. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

The knowledge sources only mention Codex models up to GPT‑5.2‑Codex; there is no reference to any “Codex 5.3” model. [GPT-5.2-Codex; Using GPT-5.2]

So:

  • There is documented support for gpt-5.2-codex (and earlier gpt-5.1-codex / GPT‑5‑codex variants), including that gpt-5.2-codex is the model that powers Codex and Codex CLI. [Using GPT-5.2]
  • The sources do not show any gpt-5.3-codex or “Codex 5.3” entry, so I can’t confirm that such a model exists or is available.

If you’re looking in the model picker or Codex surfaces and don’t see “5.3,” it’s likely because, based on these docs, the latest Codex model currently documented is gpt-5.2-codex.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
