What is Nano Banana 2?

Nano Banana 2 is the codename for Google's Gemini 3.1 Flash Image Preview API, designed for low-latency, high-quality image generation and editing.

Which aspect ratios are supported?

It supports a wide variety of ratios including 1:1, 16:9, 9:16, 21:9, 4:3, 3:2, and several panorama options like 4:1 and 8:1.

Does this skill support high-resolution 4K images?

Yes, it supports four specific resolution tiers: 512px for fast iterations, 1K as the default, 2K for medium quality, and 4K for print-quality or high-resolution needs.

Can I use my own images as references?

Absolutely. You can provide up to 14 reference images using the --input-image flag to help the model maintain consistency in character, style, or specific objects.
