Question 1

What changed from Nano Banana 2 to Nano Banana 2.1?

Accepted Answer

Google tuned the same workflow rather than replacing it. Images come out sharper and more natural. Text on signs, labels, and posters is cleaner, in many languages. The model follows long prompts more closely and holds a subject steadier from one edit to the next. It also costs about half as much per image at 1K and 2K, and less at 4K too.

Question 2

Which Nano Banana should I use?

Accepted Answer

Start with Nano Banana 2.1 for everyday generation and editing. It is the newest of the efficient tiers and the one Google recommends for new work. Pick Nano Banana 2 Lite for high volume at one flat price and a fixed 1K size. Pick Nano Banana Pro when a single image has to be perfect, with the tightest layout and the strongest likeness. Nano Banana 2 stays in Visual Sandbox for work already built around it. All of them share one composer, so you can switch on the same project.

Question 3

Can I edit existing photos with Nano Banana 2.1?

Accepted Answer

Yes. Attach one or more reference photos and describe the change in plain language. The same model generates from a prompt and edits from a reference. Swap a backdrop, change an outfit, restyle a scene, or blend elements from several photos into one frame. Name what should change and what should stay. Set the aspect ratio to Match Ratio to keep the shape of the first reference.

Question 4

Can Nano Banana 2.1 keep a character consistent across a series?

Accepted Answer

Yes. Attach reference photos of the character to each run and describe the new scene. Nano Banana 2.1 holds the face, the build, and the styling across new poses, outfits, and lighting, and it holds them more steadily than Nano Banana 2. A natural fit for storyboards, comic panels, photo series, and brand campaigns with a recurring face.

Question 5

What does search grounding do in Nano Banana 2.1?

Accepted Answer

It lets the model look things up while it draws. Turn on Web Search for current facts, such as the weather in a city, a recent event, or the details of a real product. Turn on Image Search to pull web images as visual context for something you name in words, like a specific car or a plant species. Image Search turns on Web Search with it. Leave both off for imagined scenes. Neither adds to the price of the image.

Question 6

What resolutions and aspect ratios does Nano Banana 2.1 support?

Accepted Answer

Three resolutions: 1K, 2K, and 4K. Use 1K to iterate, 2K for product shots and landing pages, and 4K for posters, print, and infographics. Ten aspect ratios run from a wide 21:9 to a tall 9:16, including 4:5 and 5:4 for social feeds. Match Ratio joins them for an edit. Higher resolutions take a little longer and cost a little more.

Question 7

How do I write prompts that work well with Nano Banana 2.1?

Accepted Answer

Describe the subject, the composition, the lighting, and the mood, in that order. Quote any text that must appear, and say where it sits and how large it is. For posters and infographics, describe the layout as well as the content. Attach a reference for anything that is hard to put into words, such as a face, a product, or a style. Turn on search grounding when the image must match a real brand, place, or event.

Question 8

How much does a Nano Banana 2.1 image cost?

Accepted Answer

A few cents per image, with the price set by the resolution you pick. Web Search and Image Search each add a small charge. Visual Sandbox shows the cost before you generate and charges per image when the result arrives. There is no subscription and no monthly minimum.

Question 9

Does Nano Banana 2.1 add a watermark to generated images?

Accepted Answer

Yes, an invisible one. Google embeds a SynthID watermark into every Nano Banana 2.1 image. The picture looks the same to the eye, and Google's verification tools can detect the mark. There is no visible logo or stamp on the image.

Question 10

Can I use Nano Banana 2.1 images commercially?

Accepted Answer

Yes. Google's terms allow commercial use of generated images. You stay responsible for the prompt and the final use, especially when the output includes a likeness, a logo, or copyrighted material. Creators on Visual Sandbox use the Nano Banana family for client work, advertising, and product photography.
