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
- Everyday work that has to be both good and fast
- Anything you expect to revise several times — each round is quick, so iterating is cheap
- Text in the image without paying for the Pro tier
Where it is not the right pick
Upstream charges a premium for 2K and 4K output (1.5x and 2x the base tier). uooki bills at the base tier, so very high resolution requests can cost the upstream more than we charge.
When to reach for something else
- Nano Banana Pro
The brief is complex enough that instruction-following matters more than speed.
- Nano Banana 2 Lite
You are running enough volume that price beats quality.
- GPT Image 2
Text inside the image is the whole point.
