Every picture here came out of Nano Banana 2.1 on NanoBanana2Pro. Open one to load its prompt and settings into the generator. A new run gives you a close variation, not a copy.
Use cases
Assets for a shop, a campaign or a comic, each started from a short written brief.

Write the headline, the offer and the feeling. Draft at 1K, then render the one you like at 4K.

A name, a mood and a few colours give you a mark and mockups on one sheet. Once a direction lands, send it back to refine it.
One big subject and a few huge words that survive on a phone screen. Use a 16:9 or 9:16 ratio and iterate cheaply at 1K.

Spell out each stage and its label to get tidy panels with simple icons. Web search can pull in current figures, but verify every fact before it goes out.

One character in several moods on a single sheet. Attach an earlier sheet to keep the same face and colours.

Lay out the beats panel by panel with one cast. Attach earlier panels as references to keep faces and costumes consistent.
Photo editing
Left is the file we attached. Right is what Nano Banana 2.1 made from the prompt underneath.


Only the words change. The tram, the colours and the style of the lettering are left in place.
Change the title to "PORTO" and the subtitle to "City of Bridges". Keep everything else the same.
How it works
Type what you want in your own language and put any exact wording in quotes. For an edit, add up to 14 images and say what must stay the same.
Choose 1K, 2K or 4K, one of 14 ratios, and JPEG or PNG. The credit cost updates on the button as you change them.
Send a result back for another round of changes, or download it as it is. Everything stays in your library.
Why NanoBanana2Pro
Nano Banana 2.1 is tuned for visual design, steady subjects and long instructions. These are the settings NanoBanana2Pro puts beside the prompt box.
Try layouts at 1K, then render the keeper at 2K or 4K. Banners and tall columns go as far as 8:1 and 1:8, ratios most generators skip. Seedream 5.5 is still in the model menu.
Posters, labels and menus come back with sharper type. Put the exact words in quotes, say where they go, and check the spelling before you print.
Give Nano Banana 2.1 a product, a model and a location, and say what to keep. One to three references give the steadiest result on a simple edit. Every attached image adds a small, listed cost.
Turn on web search for current information, or image search to ground Nano Banana 2.1 in real reference pictures. Each adds a small, listed charge, and both stay off until you ask.

FAQ
Create an image from a prompt at 1K, 2K or 4K, edit with as many as 14 attached images, and use web or image search when a picture depends on real facts. Your results are saved in your library.
Nano Banana 2.1 is Google's image generation and editing model, an update to Nano Banana 2 with gains in visual design, subject consistency, prompt adherence and text rendering. NanoBanana2Pro offers its text-to-image and edit endpoints.
Nano Banana 2.1 updates Nano Banana 2, while Nano Banana Pro is a separate Google model. NanoBanana2Pro runs 2.1, not Pro or the older 2, despite the word Pro in our name. Seedream 5.5 is the other model in the menu.
Web search and image search are billed per run, roughly 3 credits each, on top of the image. Both are off by default. Use them when the picture depends on current facts or real reference images.
New accounts receive enough free credits for one 1K image at the default settings. To continue, choose a plan or a one-off credit pack. The cost of each run appears on the button first.
Short headlines, labels and prices are the best case. Put the exact wording in quotes and say where it belongs. Long passages and very small type can still come out wrong, so check everything before you print it.
Attach the photo, describe the change and name what should stay as it is. Add more images, up to 14, to bring in a person, a product or a look. If you leave the ratio on Auto, the output follows your image.
Name the purpose first, such as a poster or a listing photo, then the subject, layout, light and style. Long, multi-part briefs are fine. Quote exact text. On an edit, say what changes and what must stay. Pick the ratio from the menu rather than describing it.
1K, 2K and 4K, in 14 aspect ratios from 8:1 banners to 1:8 columns. In our tests a 16:9 image at 4K measured 5504 x 3072. Extreme ratios have few pixels on the short side: 8:1 at 1K came out at 2928 x 352.
