What Nano Banana can do

  • An image from a description: a scene, a character, a product shot, an illustration in the style you want.
  • Photo edits in words: “replace the background with the sea at dusk,” “put a gray blazer on him.”
  • Up to 14 reference images in one request: face, clothes, objects, style.
  • Nano Banana Pro aspect ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9.
  • One image per run — to get variations, run it again.

How to write a Nano Banana prompt

  • Start with the main thing: who or what is in the frame, where, what the light is like, what style.
  • For an edit, say what to change and what to keep: “keep the face and pose, replace the background with a snowy forest.”
  • If you attach several photos, say what to take from each: “the face from the first photo, the jacket from the second.”
  • There are ready-made prompts in the gallery on the home page: press Try it, and the prompt opens in the studio.

Nano Banana Pro vs Nano Banana 2

Pro — when you need maximum quality in 4K and edits from several references. Nano Banana 2 — when you want more variations for the same credits or a narrow banner format. Lite — for drafts and quick checks of an idea.
