What AI models does Nano Banana use?

Nano Banana defaults to Gemini 3.1 Flash for speed and cost-efficiency, but it also supports Gemini 3 Pro for tasks requiring the highest possible image quality.

Can I create images with transparent backgrounds?

Yes. By using the transparent flag, the skill generates the asset on a green screen and automatically uses FFmpeg to remove the background, providing a clean PNG.

Does it support different aspect ratios?

Absolutely. Nano Banana supports a wide range of ratios including 1:1, 16:9, 9:16, 4:3, 3:2, 21:9, and more to fit any platform requirement.

How do I track my API spending?

The tool automatically logs the cost of every generation to a local JSON file. You can view your total expenditure at any time by running the costs command.
