GPT Image 2.5
OpenAI
縦構図で本物の4Kを出せる唯一のモデル —— 2881×3840、アップスケールではありません。 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
- 縦位置のポスターや表紙 —— 原寸で見ても文字が崩れないこと
- 印刷に回す画像や、スマホで全面に表示する画像
- 画像内の文字を読ませたいとき —— 強さはGPT Image 2と同等で、1枚あたりは安く済みます
Where it is not the right pick
ピクセル指定は受け付けず、名前付きの比率しか通りません。マスク欄もないため、一部だけの描き直しはできません。この2つはGPT Image 2の担当のままです。提供元は1系統だけなので、必ず生成できることが前提の場面では頼らないでください。
When to reach for something else
- GPT Image 2
マスクを使った部分描き直しが必要なとき、または比率ではなくピクセル寸法を渡すとき。
- Nano Banana
同じ被写体を一連の画像すべてで保つ必要があるとき。
