What Is Nano Banana 2?
Nano Banana 2 is the standard tier of Google's Gemini image family, and it covers text-to-image, image-to-image, local editing and multi-reference in a single model. Its most useful trait is that edits don't blow up the rest of the frame: ask it to swap a background or change a jacket and everything else stays put, which most pure text-to-image models struggle with.

Nano Banana 2 Settings Explained
Resolution
1K for drafts, 2K for social, 4K for print and ecommerce hero images. Changing it updates the credit cost immediately.
Reference Images
Up to 4. Referring to them explicitly in the prompt ("image 1", "image 2") is far more reliable than describing them.
Search Grounding
Text-to-image only. The model researches before generating, at the cost of a slower response.
The panel above shows only the parameters Nano Banana 2 actually supports. Switch versions and unsupported controls disappear rather than sitting there doing nothing.
Nano Banana 2 Prompt Examples
Product photography
A premium skincare bottle on white marble, soft studio lighting, subtle reflection, commercial product photography, 45mm lens
Local edit
Replace only the sky with an overcast evening sky, keep the building and people unchanged
Spelling out "keep … unchanged" in edit mode dramatically reduces collateral changes.
Multi-reference
Use the person from image 1 and the jacket from image 2. Full-body studio shot on a neutral grey backdrop.
Nano Banana 2 Test Results
Testing in progress
Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for Nano Banana 2, so this page shows no scores. We do not publish numbers we have not measured.

Frequently Asked Questions
Does Nano Banana 2 understand non-English prompts?+
Yes, though English is usually more precise for photographic terms like lens, lighting and film stock. Mixing a native-language description with English technical terms works well in practice.
How do I stop an edit from repainting the whole image?+
Use Edit Image mode and state what must be preserved, for example "keep the product and shadow unchanged".
Do failed generations cost credits?+
No. Failed generations are never charged.
