Nano Banana Pro is Google's highest-quality image model. It has the most world knowledge of the three, the best text and translation, and keeps brands and characters consistent.

## When to use it

- Finished work: campaigns, product photos and anything with type.
- Keeping a brand's look or a character the same across many images.
- For speed or volume, use [Nano Banana 2](https://sloosh.ai/docs/nano-banana-2.md).

## How to prompt it

- Describe a finished photo, not a list of tags: product, surface, light, then the text.
- Put each line of text in quotes, name the font style and say where it sits.
- With references, say what to keep from each one.
- Set the aspect ratio in the chip rather than in the prompt.

## Example

Text only, adapted from Google's own product-ad example: a beauty shot with three stacked words.

## Frequently asked questions

### What is Nano Banana Pro best for?

Nano Banana Pro is best for finished work: campaigns, product photos and images with text. It keeps a brand's look or a character the same across many images. For quick drafts and big batches, use [Nano Banana 2](https://sloosh.ai/docs/nano-banana-2.md) or [Nano Banana Lite](https://sloosh.ai/docs/nano-banana-lite.md) and rerun the winner on Pro.

### How do I put text in an image with Nano Banana Pro?

Put each line of text in quotes, name the font style and say where it sits, for example three lines in a thin sans-serif stacked to the right of the product. For another language, write the prompt in English and give the exact translated words in quotes. Turn Enhance off so your wording reaches the model as typed.

### How do I keep the same person or product across images with Nano Banana Pro?

Give each person or product a short name and reuse it in every prompt: "Mia is the woman in image 1." Add a keep line, such as "Keep Mia's face and hair exactly as in image 1." Without the name and the keep line, Nano Banana Pro may draw a different person.

### Does Nano Banana Pro make 512px drafts?

No. Nano Banana Pro makes 1K, 2K or 4K in Sloosh. The 512px option is only on Nano Banana 2, and Nano Banana Lite makes 1K only. Draft on one of those cheaper models, then render the final on Nano Banana Pro with the same prompt.

### How many reference images can Nano Banana Pro use in Sloosh?

Nano Banana Pro takes up to 14 reference images in Sloosh Studio, the same as the other Nano Banana models. With references, say what to keep from each one, such as the product's label or the person's face. Spacelab's Image Model node takes up to 10 references.
