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.

Where it is not the right pick
提供元は2K・4K出力に割増料金を設定しています(ベースティアの1.5倍・2倍)。uookiの請求はベースティア基準なので、超高解像度のリクエストは提供元側のコストが、こちらの請求額を上回ることがあります。
