Nano Banana 2 is the name Google uses for Gemini 3.1 Flash Image. Google positions it as a balance of speed and quality: 4K generation, broad world knowledge and consistency across multiple reference images. It can also use Google Search while generating, which helps when an image depends on real facts such as names, figures or landmarks.
On ImgAI the search switch is in the creator's settings, and you can add up to 14 reference images. Output is 1K, 2K or 4K in 14 aspect ratios, including extra-wide 4:1 and 8:1 banners. An image costs 25–40 credits. Like all Google image models, results carry Google's invisible SynthID watermark.
Based on the model's published capabilities and what we actually generated, to help you judge whether it fits your task.
With search on, charts and comparisons can draw on real data. Our "tallest buildings" example came out with correct heights.
Natural light and appetizing detail at low cost — good for menus, blogs and social posts.
Friendly 3D characters that stay recognizable when you reuse them as reference images.
Native 4:1, 1:4, 8:1 and 1:8 ratios for website headers, sidebars and long strips.
Specs come from the configuration currently available on this site; the creator always shows the live price. Failed generations are refunded automatically.

These come from real generations — read them alongside the original prompts in the examples.
Search helps with real names, numbers and places. For pure imagination it adds nothing, so leave it off.
Search improves accuracy but does not guarantee it. Verify every figure in an infographic before publishing.
To keep a character or product the same across images, add earlier results as reference images and describe only what changes.
Wide formats change the composition. Choose 16:9 or 4:1 first, then describe left, centre and right.
