AI images with Nano Banana — versions and examples

What Nano Banana is

Nano Banana is a model for generating and editing images from Google, part of the Gemini family. It creates images from a text description and edits existing photos according to an instruction, standing out with natural, consistent changes — it keeps the look of the scene and the objects while it applies the edits.

Nano Banana quickly became popular precisely for the quality of its editing: you can change details, add or remove elements and transform an image without the result looking artificially “pasted on”. It suits designers, marketing, e-commerce and anyone who wants to create or rework visual material quickly.

On genkiki.com Nano Banana is available in several versions, each in the text to image and image editing modes.

Versions and options on generiram

The platform offers three variants, so you can choose the balance between speed and quality.

VariantModesWhat it is for

Nano Banana 2Text to image, Image editingA new generation with improved quality
Nano Banana ProText to image, Image editingThe highest-quality variant for the best result

Text to image

You describe what you want to see — scene, style, composition — and Nano Banana creates a new image from the description.

Image editing

You supply an existing photo and an instruction on what should change. Nano Banana applies the edit while aiming to keep the naturalness and the look of the rest of the image — the strength of this model.

Strengths

  • Natural, consistent editing — the changes look organic.
  • Good preservation of the look of the scene and the objects when editing.
  • A flexible choice between the basic, the new generation and the Pro variant.
  • Two starting points: text or an existing photo.
  • Suitable both for creating and for reworking visuals.

What it is good for

  • Product photos and visuals for e-commerce.
  • Editing existing photos — adding, removing or changing details.
  • Marketing and advertising visuals.
  • Design concepts and quick drafts.
  • Content for social media and blogs.

How to start

Open the genkiki.com AI Studio, pick a Nano Banana variant and the text to image or image editing mode. Describe what you want or upload a photo to edit and start the generation. For the best quality, use the Pro variant.

Nano Banana Pro

文字照片
畫面比例： 1:1, 9:16, 16:9 價格： 291 點數

擅長

  • The best TEXT inside the image on the market — it handles whole paragraphs, not just a caption, and foreign alphabets too
  • Three sizes: 1024×1024, 2048×2048 and 4096×4096 — four times more pixels than the previous generation, which was locked at 1024
  • It takes up to 14 reference photos at once and keeps up to 5 different faces the same across the whole series
  • It is built on a reasoning model — it understands what the prompt wants, not just which words are in it
  • Strong on infographics, diagrams and layout, where the arrangement carries the meaning

不擅長

  • Slow: about 20 seconds per shot against 12 for the previous generation — the price of 4K and of reasoning
  • Expensive at 4K — the biggest step costs almost double the 2K one
  • Not the best for a photorealistic portrait — the specialists are ahead of it there
  • Long paragraphs do come out, but they take a few tries before the layout settles

不要用它來做

  • Don’t use it for a quick batch of test shots — it’s slow and expensive, do those on a light tier
  • Don’t use it for a close portrait whose skin has to hold up to scrutiny
  • Don’t ask for 4K if the image will only be seen on the web — you’re paying for pixels nobody will see

典型用途

  • An ad or a poster with readable text in your language right in the image
  • An infographic or a diagram with a lot of text
  • The same character, or several characters, across a series of shots
  • An image for print, where you need the maximum pixels
  • Packaging, a label, a menu — anything with a lot of lettering
