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
- 日常工作,品質和速度都要顧
- 預期要改好幾輪的案子——每一輪都很快,反覆修改的成本低
- 圖片裡要有文字,又不想付 Pro 檔位的價格
Where it is not the right pick
上游對 2K、4K 輸出加收溢價(分別是基礎檔位的 1.5 倍和 2 倍)。uooki 按基礎檔位計價,所以超高解析度的請求,上游成本可能比我們收的費用還高。
