Create and Edit Pictures with Nano Banana 2
Nano Banana 2 is Google's Gemini 3.1 Flash Image model, built to bring Nano Banana Pro style intelligence to Flash speed. Describe a scene in plain sentences, or upload up to 14 reference images and tell it what to change, then pick 1K, 2K or 4K and see the credit cost first.
What Nano Banana 2 Can Do for Your Images
Nano Banana 2 handles both fresh generation and edits of pictures you already have. These are the controls the generator puts in front of you.
Text prompts and reference edits
Start from a sentence, or switch to editing and add reference images. Edit mode needs at least one image and accepts up to 14 of them in a single request.
1K, 2K and 4K output
Draft at 1K for 7 credits, move to 2K for 10, and use 4K for 15 when the image is headed for print or a large display. Reference count does not change the price.
From square to extreme banners
Choose auto, 1:1, 16:9, 9:16, 4:5, 21:9 or tall and wide shapes like 1:4, 4:1, 1:8 and 8:1. Auto lets the model pick a shape that suits the prompt.
Legible text inside the picture
Google highlights accurate, readable text for cards, posters and mockups, including translating the words in an image. Quote the exact copy and check the result before you publish.
Writing Prompts That Nano Banana 2 Follows
Google recommends describing the scene the way you would brief a photographer or designer, in sentences, rather than stacking keywords. A few habits make that easy.
Describe, do not list
Combine subject, action, location, composition and style in one or two sentences. A narrative prompt gives the model relationships to work with, which a string of tags does not.
Borrow the language of photography
Name the lens, the light and the grade: wide angle, macro, f/1.8, golden hour, soft studio light. These terms steer framing and depth more reliably than adjectives.
Put exact words in quotes
For signs, labels and headings, write the text in quotation marks and describe the lettering, for example bold white sans-serif. Say which language the text should be in.
State what stays and what changes
When editing, start with a verb such as remove, replace or transform and list what must not move. Say what you want to see instead of what to avoid.
Three Nano Banana 2 Images and the Prompts Behind Them
A three-panel comic of cloud types
Cumulus, stratus and cirrus each get a panel with a bold title, a short caption and a matching landscape. It shows how a model can hold readable headings and body text together with illustration, as long as the brief names each panel.
An aerial photo of a misty valley
A lake and river wind through green hills under low cloud, with a single road curving along the slope. A photographic prompt that names the viewpoint, the weather and the colour grade is what separates this from an illustration.
A craft-style water cycle diagram
Felt, cotton wool, beads and paper cut-outs are laid flat on a pale surface with labelled stages and arrows. It is a good model for explainers where the look of the materials matters as much as the labels.
Nano Banana 2 Production Notes
Choose the ratio before the prompt
A 1:8 strip and a 1:1 tile need different compositions. Set the shape first, then describe where the subject and the text sit inside it.
Proof every word
Even when text renders well, check spelling, spacing and any translated line. Treat generated lettering as a draft until a person has read it.
Who Uses Nano Banana 2 and For What
E-commerce product shots
Upload product photos and style references together and ask for a new setting while the item itself stays recognizable.
Posters, cards and social graphics
Generate a layout with a headline in quotes, then make a 9:16 and a 1:1 version for different feeds.
Wide banners and headers
Use 4:1 or 8:1 for site headers, newsletter strips and event signage that ordinary ratios crop badly.
Localized creative
Rewrite the words inside an existing image for another market, then review every line for spelling before it ships.
Educational diagrams
Turn a lesson into a labelled infographic or a comic strip that students can read at a glance.
Fast drafts before a final render
Explore ideas at 1K for 7 credits and pay for 2K or 4K only when a direction has been approved.
