About the tool
What is the Nano Banana generator?
Nano Banana is a batch proofing workbench for e-commerce and ad operations. Instead of generating one image at a time, you upload 0–2 product reference images, write a single prompt or paste up to 20 creative directions, and receive a fixed contact sheet of variants to compare side by side.
Every output is an independent task with its own status and billing. Blocked, failed, or cancelled slots release their credit reserve, so partial failures never take the whole batch down—and you only pay for outputs that succeeded and can be downloaded.

Frequently asked questions
Every batch runs on gemini-3.1-flash-lite-image. You choose the resolution per batch: 1K for fast previews, 2K as the recommended default, or 4K for maximum detail. 4K requires an active subscription; there is no multi-model selection—what you see on the panel is exactly what runs.
