What is Nano Banana 2?

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.

Nano Banana 2 prompt tips

These come from real generations — read them alongside the original prompts in the examples.

  1. Turn on search only when facts matter

    Search helps with real names, numbers and places. For pure imagination it adds nothing, so leave it off.

  2. Still check the numbers

    Search improves accuracy but does not guarantee it. Verify every figure in an infographic before publishing.

  3. Use references for consistency

    To keep a character or product the same across images, add earlier results as reference images and describe only what changes.

  4. Pick the ratio before you write

    Wide formats change the composition. Choose 16:9 or 4:1 first, then describe left, centre and right.
