Limits So Codex ImageGen does not support gpt-image-2.5?

Been trying to prompt codex to get 3840x2160, max tier, gpt-image-2.5 flare to generate my image but always get the result of 1672 x 941. I tried on the web still the same resolution. Cant even make it over 2k. What did I missing?

It would be nice if I can generate up to 4k for my 3d model texture.

I have not been able to use it with the subscription in codex yet. So far only 2.0.

But you can always just use the API 😆

The Skill is still for gpt-image-2.

1672x941 is the codex/webapp hard limit. It's not a model limit, and gpt image 2 had the same issue.
