Website: All Image AI

Language: English

Nano Banana 2 is the standard tier of Google's Gemini image family, and it covers text-to-image, image-to-image, local editing and multi-reference in a single model. Its most useful trait is that edits don't blow up the rest of the frame: ask it to swap a background or change a jacket and everything else stays put, which most pure text-to-image models struggle with.

## Model details

- Developer: Google
- Status on All Image AI: Active
- Last verified: 2026-08-20
- Maximum output: 4K
- Modes: Text to Image, Image to Image, Edit Image, Multi-reference, Product Image
- Reference images: up to 4
- Resolutions: 1K, 2K, 4K
- Aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 21:9

## Best for

- Local edits that must leave the rest of the image untouched
- Character or product consistency across 2–4 reference images
- Social images and simple posters with text
- Ecommerce product shots: background replacement and scene rebuilds

## How to use

1. Pick Nano Banana 2 in the version cards.
2. Choose a mode: Text to Image for a description, Edit Image to change an upload, Multi-reference for several sources.
3. Write the subject first, then lighting, lens and style.
4. Choose ratio and resolution — the Generate button shows the exact credit cost.
5. Chain the result straight into Upscale, Remove Background or Create Variations.

## Settings explained

### Resolution

1K for drafts, 2K for social, 4K for print and ecommerce hero images. Changing it updates the credit cost immediately.

### Reference Images

Up to 4. Referring to them explicitly in the prompt ("image 1", "image 2") is far more reliable than describing them.

### Search Grounding

Text-to-image only. The model researches before generating, at the cost of a slower response.

## Prompt examples

### Product photography

> A premium skincare bottle on white marble, soft studio lighting, subtle reflection, commercial product photography, 45mm lens

### Local edit

> Replace only the sky with an overcast evening sky, keep the building and people unchanged

Spelling out "keep … unchanged" in edit mode dramatically reduces collateral changes.

### Multi-reference

> Use the person from image 1 and the jacket from image 2. Full-body studio shot on a neutral grey backdrop.

## Limitations

- Dense multilingual layout still belongs on Nano Banana Pro
- 4K noticeably increases both generation time and credits
- Heavily stylised looks (thick oil paint, for example) are better served by specialist models

## Pricing and credits

Credits for one image at default quality and mode. Resolution, quality, reference inputs, edit mode and output count can change the total. Check the Generate button before submitting.

| Resolution | Credits / image |
| --- | --- |
| 1K | 5 |
| 2K | 8 |
| 4K | 10 |

Failed generations cost 0 credits. Catalog availability does not guarantee runtime availability; the workspace reports whether the selected model can run.

## Frequently asked questions

### Does Nano Banana 2 understand non-English prompts?

Yes, though English is usually more precise for photographic terms like lens, lighting and film stock. Mixing a native-language description with English technical terms works well in practice.

### How do I stop an edit from repainting the whole image?

Use Edit Image mode and state what must be preserved, for example "keep the product and shadow unchanged".

### Do failed generations cost credits?

No. Failed generations are never charged.
