Overview
What is Nano Banana Pro?
Nano Banana Pro is useful when the artwork has to satisfy several constraints at once. Specify what should be prominent, where the headline should sit, which product details must survive a revision, and where the image will appear. Review the result against the brief before turning it into a final asset.
The TokenHot API example uses generateContent with a 16:9 aspect ratio and 2K image size. The Playground exposes its own ratio and size choices. Pick the delivery format first, then inspect the returned image and proof any text before using it.
Make proofing part of the brief
Give the exact headline and subhead, then check spelling, spacing, and reading order at the intended size.
Preserve the details that identify the product
Attach an approved photo and name the edges, proportions, and colors that should stay consistent.
Leave room for the rest of the design
Reserve space for the headline and call to action, then inspect each crop in the actual page layout.
From brief to deliverable
Put Nano Banana Pro to work
Brand designers
Proof a poster with a short headline
Specify the exact headline and subhead, along with their reading order and placement. Use the draft to review composition and recheck the lettering before export.
- Tools you need
- The Playground and a design editor for final typography.
- Keep in mind
- Check every character against the supplied copy. Set the final text in an editor if the draft changes any wording.
View a task brief
Draft a storefront poster. Use the supplied headline and subhead verbatim, with clear visual separation. Put the headline in the upper third and keep a generous margin around it. Leave the footer blank.
Product and packaging teams
Carry one package design across two layouts
Use one approved product photo to guide separate studio and display compositions. Check the outline, lid, and brand color in both candidates.
- Tools you need
- The Playground reference input and a side-by-side review board.
- Keep in mind
- A reference guides the draft. Inspect the package proportions and replace altered label details before publication.
View a task brief
Use this approved tea-tin photo as the reference. Keep the tin shape, lid, material, and orange stripe. Compose one clean studio image with soft shadows. Use a separate request for the retail display version.
Web and campaign designers
Plan a hero with room for copy
Draft a wide composition with the product anchored to one side and room for the headline. Ask for a separate portrait composition if the placement changes.
- Tools you need
- The Playground and the target page or design mockup.
- Keep in mind
- A new ratio can shift or crop key details. Check the subject and copy area in the final layout at each breakpoint.
View a task brief
Compose a wide workspace hero with the headphones on the right and open space on the left for a headline. Keep the lighting soft and the background simple. Run a separate request at the portrait ratio and recompose for the narrower frame.
