    Same character on a bicycle

    The same stylized 3D animated character with a short silver bob, round glasses and a bright yellow raincoat, riding a pale blue vintage bicycle with a wicker basket of bread along a dirt path through a tall sunflower field.

    Same character at a night station

About Nano Banana 2

Nano Banana 2 is Google's Gemini image model for fast generation and editing; Google's own name for it is Gemini 3.1 Flash Image. Google positions it as pro-level image generation at Flash speed: it draws on Gemini's knowledge of the world, follows complex instructions closely, renders legible text and can translate the text inside an image. Its best-known strength is consistency — the same character, outfit or object carried across a whole set of images.

On Zero Kit it runs in the editor at the top of this page. Write what you want, or upload a photo and describe the change, and add up to 14 reference images when you need a character sheet, a product or a style to carry through. Output goes up to 4k, and you can make up to 4 images in one run. Nano Banana 2 is included in Plus and above.

Use it for a story told in several frames, a mascot in different places, a room restyled one step at a time or a product shown in a series of scenes. If you need the most exact rendering for a single high-stakes image, Google recommends Nano Banana Pro; the link to it is at the bottom of this page.

What Nano Banana 2 does well

One character, every angle

Describe a character once, or upload a reference, and ask for a turnaround sheet: front, three-quarter, side and back. Nano Banana 2 keeps the face, hair and outfit the same across the views, which gives you a reference you can reuse for every later scene. Google lists character consistency as one of the model's headline features, and it works for mascots and products as well as people.

A turnaround sheet of the same character from the front, three-quarter, side and back, with matching details in every view.

A clean character turnaround sheet on a soft pastel grey background showing the same stylized 3D animated character four times in a row: front view, three-quarter view, side profile and back view. She has a short silver bob, round glasses, a bright yellow raincoat with toggle buttons, teal rain boots and a small canvas tote. Identical proportions, outfit and colors across all four poses, even studio lighting, feature-animation production design quality, no text.

Edit by talking to it

Upload an image and say what should change — turn the room to night, swap the sofa for a green one, add rain on the window — and Nano Banana 2 edits that part while leaving the rest in place. You can keep going one instruction at a time, which is easier than writing one long prompt that tries to describe every detail at once.

Before and after: a plain daytime living room on the left and the same room at night with string lights and a sleeping cat on the right.

A before-and-after diptych of the same cozy living room from the identical camera angle. Left panel: a plain daytime scene with a grey sofa, a round wooden coffee table and a bare window. Right panel: the exact same room edited step by step, now at night with warm string lights along the window frame, a knitted blanket on the sofa, a mug of cocoa on the table, and a ginger cat asleep on the cushion. Furniture, layout and perspective stay identical, photorealistic interior photography.

Several references, one scene

Upload several references, such as a chair, a fabric and a lamp, and ask for a room that uses all of them. Nano Banana 2 combines them into one coherent image and keeps each object recognisable. Name each reference in the prompt so the model knows what it is for, and keep the number of references to what the scene really needs.

Three small reference cards — an armchair, a patterned textile and a brass lamp — pinned beside the finished reading nook that combines them.

A design presentation board on a warm white wall. On the left, three small printed reference cards pinned vertically: a mid-century armchair in mustard velvet, a swatch of indigo block-printed textile, and a brass arc floor lamp. On the right, a large print of the finished interior that combines all three: a reading nook where the mustard armchair has an indigo block-print cushion and the brass arc lamp glows above it, bookshelves and a large plant behind. Soft gallery lighting, clean editorial layout, no text.

Limitations to know

  • Small faces in crowded scenes can come out blurred or distorted. Google lists this as a known weakness, so keep important faces large in the frame.
  • Spelling and fine detail are not guaranteed, and translated text can miss grammar or nuance. Check every word before you publish.
  • Complex edits and blends of many images can look unnatural, and consistency can slip over a long series. Regenerate the frames that drift.

How to write prompts for Nano Banana 2

  1. Describe the character or product in the same words in every prompt of a series: name, hair, clothing, colours.
  2. For an edit, say what to change and what to keep, such as "make it night, keep the furniture and the camera angle".
  3. When you use several references, say which one is the subject and which ones are style or setting.
  4. Give the scene a light source and a time of day; the model follows lighting instructions closely.
  5. Edit in small steps. Two or three short instructions usually work better than one long one.
