They seem to be slowly moving away from having a separate coding model. With this release, they're calling the model Codex but expressly mention that it's also supposed to be more suitable than GPT 5.2 for general use.

I remember a paper coming out a while back that said training the models to code made them much better at normal tasks. It improved their logic etc.
Where did they say that?
"The model advances both the frontier coding performance of GPT‑5.2-Codex and the reasoning and professional knowledge capabilities of GPT‑5.2, together in one model, which is also 25% faster. ... With GPT‑5.3-Codex, Codex goes from an agent that can write and review code to an agent that can do nearly anything developers and professionals can do on a computer."
They're specifically saying that they're planning for an overall improvement over the general-purpose GPT 5.2.
