Using Nano Banana 2 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 Nano Banana 2” 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
- 既要好、又要快的日常出图
- 预计要改好几轮的东西 —— 每一轮都很快,反复迭代成本低
- 图里要文字,又不想为 Pro 档多付钱
Where it is not the right pick
上游对 2K、4K 输出加价(分别是基础档的 1.5 倍和 2 倍)。uooki 按基础档计费,所以超高分辨率的请求,上游收我们的钱可能比我们收用户的还多。
