About Nano Banana Pro
Nano Banana Pro is the production name DesignerBox uses for Google Gemini 3 Pro Image, Google's flagship image model, accessible through the same canvas as the rest of the platform. It produces highly photorealistic results with strong prompt understanding inherited from the Gemini family, and supports up to 5 reference images for character or style consistency across a batch.
Use it when you need top-quality output: editorial photography, hero campaign imagery, product shots that need to look real, and any work where prompt fidelity matters more than raw speed. The model handles up to 4K output, supports inpainting, outpainting, background swap, style transfer, and product-image relighting via the built-in edit modes.
On DesignerBox, Nano Banana Pro costs 5 credits per generation, the same flat rate whether you generate 1:1, 16:9, or 9:16. Available on every paid plan from Basic upwards.
Best For
Editorial photography, brand campaigns, product shots, character-consistent batches, and any work where prompt fidelity and 4K output quality are non-negotiable.
