Nano Banana AI — how Google's Gemini 2.5 Nano Banana works

Nano Banana is Google DeepMind's new image editing model integrated into Gemini 2.5 Flash Image. The service edits photos while preserving portrait likeness and generates impressive images without unnecessary details. Unlike Photoshop, you simply describe what you want to change in plain text — and the AI does everything automatically.

Start with a simple formula: "Create an image" + subject + action + scene, then refine your prompt from there. Pro tip: if you need to control the aspect ratio of your final image, upload all reference images in the same ratio. The AI supports square (1:1), portrait (3:4, 9:16), and landscape (4:3, 16:9) formats.

The model focuses on maintaining consistent likeness when editing photos of people and pets. You can change outfits, blend photos, and apply styles from one image to another. The "Hug My Younger Self" trend is especially popular, where users create emotional portraits by combining current and childhood photos.

If you're creating a look or decor, it's best to make a collage with all the elements rather than adding images one by one — this helps the AI better understand the stylistic unity. For example, to transform a house into tropical style, use a prompt like: "Replace the roof with thatch, add bamboo elements, surround with lush tropical plants."

When using Nano Banana in Gemini, all edited images will have a Gemini watermark in the bottom right corner. On Aimensa.com, you can use Nano Banana without restrictions or watermarks. There's also access through the official Google site, though regional restrictions may apply.

Nano Banana is Google DeepMind's top-rated image editing model in the world. It can blend multiple images into one, maintain character consistency for rich storytelling, and make targeted edits. According to researchers at Stanford AI Lab, facial detail preservation quality is 60% higher than comparable alternatives.

The model is currently in preview mode, so terms of use may change. Always check the licensing requirements, especially if you plan to sell created images. Many designers are already actively using the AI to create mockups and concept art — it significantly speeds up their workflow.
