What Nano Banana Pro does best
Legible text in the image
Posters, menus, diagrams and infographics: Google announces sharp text in several languages, with a wider range of fonts, textures and calligraphy. Always check the spelling and the figures.
Consistency across 8 references
Add up to 8 reference images to keep a logo, a product or a person consistent from one image to the next. Google says the model keeps the resemblance of up to 5 people.
Built for precision
Google reserves Pro for complex work where accuracy matters more than speed: the model reasons before it renders and can test its composition with interim images.
Translate and adapt a visual
Google highlights translation and localization: translate the text of an ad or a package while keeping the layout, then adapt the setting to another audience.

Adapt an ad for Dakar
- Reference: the ad
- Auto

Adapt this ad for a campaign in Dakar: translate all the text into French, keep the same layout, fonts and colors, and replace the setting with a busy Dakar street in the late afternoon.
Tips for better results
- Give the context and purpose of the visual (shop-window poster, ad, training material): Google suggests explaining your intent, which the model takes into account.
- Write the exact text in quotation marks and specify the font (serif, handwritten, chalk…) and layout: Google suggests being explicit about the text, font and design.
- For an edit, describe the change, then add “keep everything else the same: style, lighting and composition”.
- For studio-style changes, use photography terms: “soft light at 45 degrees”, “shallow depth of field”, “85 mm lens”.
- With several references, give each one a role (“image 1: the logo, image 2: the product”).
- Test the composition in 1K, then move to 2K or 4K for the final version.
Good to know
- To explore several directions, make your drafts with Nano Banana 2 Lite, then take the best idea to Nano Banana Pro for the final version.
- Pick 9:16 for stories, Reels and TikTok, 4:5 or 1:1 for feed posts, 16:9 for YouTube and 2:3 for a poster.
- To edit a result, add it from your Deepnia library as a reference in a new creation, then describe the next change.
- Before you publish, proofread every piece of text and every translation, and check the figures, small faces and fine details.
