Built for complex, production-grade work
Nano Banana Pro is powered by Gemini 3 Pro Image — Google’s most capable image generation model. Where Nano Banana 2 excels at speed and volume, Nano Banana Pro excels at depth: multi-subject identity preservation, precise localized edits, camera transformations, and highly detailed prompt adherence. It’s the right choice when your output needs to hold up to client scrutiny.

How to use
Write your prompt
Be specific about subjects, lighting, and composition. Nano Banana Pro follows complex multi-part instructions reliably.
Attach reference images (optional)
For multi-subject consistency, upload your reference images. The model preserves identity across all subjects.
Prompting tips
- Name your subjects explicitly — “A woman in a red blazer (Subject A) and a man in a navy suit (Subject B) shaking hands” gives the model clear anchors for identity preservation.
- Use localized edit instructions — After generating, follow up with targeted edits: “Change the background to a blurred office interior” or “Shift the lighting to golden hour.”
- Let Google grounding handle real-world references — For known brands, locations, or products, name them directly. Nano Banana Pro will render them accurately.
Example prompts
A product shoot featuring a cream-colored luxury skincare bottle (Subject A) and a matching moisturizer jar (Subject B) on a pale stone surface, dramatic side lighting, high-end editorial photography.
A tech CEO (Subject A) being interviewed on stage at a large conference, blurred audience in background, professional event photography, warm stage lighting.
