GPT Image 2.5
OpenAI
这里唯一能在竖构图下真出 4K 的模型 —— 2881×3840,不是放大出来的。 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
- 竖版海报和封面 —— 满尺寸看,字也得是清楚的
- 要拿去印刷、或者在手机上满屏铺开的图
- 图里的文字要能读 —— 和 GPT Image 2 一样强,单张还更便宜
Where it is not the right pick
它不接受像素尺寸,只认命名比例;也没有蒙版字段,做不了局部重绘。这两件事继续留给 GPT Image 2。它只有一条供应商线路,所以「必须出图」的场合别押它。
When to reach for something else
- GPT Image 2
你要做蒙版局部重绘,或者传的是精确像素尺寸而不是比例。
- Nano Banana
同一个主体要贯穿一整套图。

Model id
What uooki calls upstream when you pick GPT Image 2.5. You never need this to use it — it is here so the vendor name and the actual model are unambiguous.
