GPT Image 2.5
OpenAI
세로 화면에서 진짜 4K를 뽑는 유일한 모델이에요 — 2881×3840, 업스케일이 아니에요. OpenAI's newest image model. Best-in-class legible text, and the only one that renders true 4K in portrait ratios. Cannot take pixel sizes or masks — use GPT Image 2 for those.
Using GPT Image 2.5 in uooki
uooki has no model picker. You name the model in the conversation and the agent routes to it — “draw the packaging mockup with GPT Image 2.5” is the whole interface. Common spellings and older ids resolve to the same model, so you do not have to match our internal naming.
Leave the model out and the agent picks one for you based on what you asked for. Naming it is for when you have a reason to — this page is about those reasons.
What it is good at
- 세로 포스터와 표지 — 원본 크기로 봐도 글자가 또렷해야 하는 작업
- 인쇄로 넘기거나 휴대폰에서 꽉 차게 보여줄 이미지
- 이미지 안의 글자가 읽혀야 할 때 — GPT Image 2와 같은 수준인데 장당 더 저렴해요
Where it is not the right pick
픽셀 크기는 받지 않고 이름이 정해진 비율만 받아요. 마스크 필드도 없어서 일부만 다시 그리는 건 못 해요. 이 두 가지는 계속 GPT Image 2 몫이에요. 공급 경로가 하나뿐이라 반드시 나와야 하는 자리에는 기대지 마세요.
When to reach for something else
- GPT Image 2
마스크로 일부만 다시 그려야 하거나, 비율이 아니라 정확한 픽셀 크기를 넘길 때.
- Nano Banana
같은 피사체가 이미지 여러 장에 걸쳐 유지돼야 할 때.
