Character consistency

One character, five scenes.

Each step uses the previous step's picture as image 1 and moves her somewhere new. Her face, platinum pixie cut, beauty mark and gold hoops carry through every turn, across light, angle and outfit. Pick a step and drag the divider.

The same cabin in deep winter snow after a Nano Banana 2.1 edit

A red cabin by a summer lake with a young woman on the dock, before a Nano Banana 2.1 edit

Summer to winter

Deep snow, a frozen lake and falling snow; the cabin, the dock, the treeline and the framing stay where they were, and she is dressed for the cold.

Prompts

Edit

Make it the middle of winter: deep snow covers the meadow and the cabin roof, the lake is frozen, the canoe is a snow-covered shape on the shore, light snow is falling, and the young woman sits on the dock in a red knit hat and a winter coat. Keep the cabin, the dock, the treeline and the camera angle exactly the same.

Original image

A small red wooden cabin by a lake in summer, a green meadow full of wildflowers, a wooden canoe pulled up on the shore, and a young woman sitting on the dock with her feet in the water. Clear blue sky, natural landscape photography.

Clear a crowded street

A dozen tourists and five scooters removed, the cobbles filled in, and only the couple taking a selfie kept.

Prompts

Edit

Remove every tourist and every scooter from the street. Keep only the young couple taking a selfie in the middle, and keep the buildings, the laundry, the light and the camera angle exactly the same.

Original image

A narrow cobbled street in an old Italian town in the afternoon. Five parked scooters line both sides, a dozen young tourists in their twenties walk in both directions, and in the middle of the street a young couple takes a selfie together.

A painting, a floor lamp, a rug and a sleeping dog, each where the prompt puts it. The reader, the sofa and the window light are unchanged.

Prompts

Edit

Add a large abstract painting in terracotta and sage green on the wall above the sofa, a tall brass floor lamp to the right of the sofa, a round cream wool rug in front of it, and a golden retriever asleep on the rug, fully separate from her feet. Keep the woman, the sofa, the window and the light exactly the same.

Original image

An outfit from four product photos

Four flat packshots, one look in motion: washed denim, rust corduroy, chunky sneakers and gold-framed sunglasses. Four images is also what a free account can attach.

Prompt

Image 1 is a denim jacket, image 2 corduroy trousers, image 3 sneakers, image 4 sunglasses. A young woman, about 23, with long dark box braids, wears all four items exactly as they look in the references, a plain white tee under the jacket.

Who, what and where

A selfie, a camera and a viewpoint, each from its own photo, become one travel shot: his tied-back hair and fleece, the silver-ringed camera on its tan strap, the railing and the ridges.

Prompt

Image 1 is a person, image 2 is a camera, image 3 is a place. The young man from image 1 stands at the wooden railing of the mountain viewpoint from image 3 at sunrise, raising the camera from image 2 to his eye to photograph the misty ridges. Same face, hair, earring and navy fleece; the same camera with its tan strap around his neck. Three-quarter view from beside his shoulder, warm rim light, natural travel photography.

A style from one print

The two inks, the grain, the halftone and the paper of a risograph print, applied to a new subject. Where the inks overlap a third tone appears, as it does in real risograph printing.

Prompt

Use the exact style of image 1 - a two-ink risograph print in fluorescent pink and teal on off-white paper, with grain, halftone shading and slight misregistration - for a new illustration: a fox crossing a quiet city street at night under a streetlamp, tall buildings on both sides, a crescent moon above. Do not copy the lighthouse or the sea.

Four matching mugs with different rim colors and a plate, made from one packshot by Nano Banana 2.1

A product line from one packshot

One mug becomes a range: the same handmade shape and speckled glaze, four rim colors in the order asked, and a matching plate.

Prompt

Create a product family from image 1: four mugs in a row, all with the same handmade shape, the same speckled oatmeal glaze and the same dipped rim, but the rims are cobalt blue, mustard yellow, forest green and terracotta. A matching small speckled plate sits in front of the row. White studio background, soft shadows, catalog photography.

Photorealism

Natural, candid, in motion.

Name the lens, the shutter and the light. Real skin, motion and weather come out the way a photographer would shoot them.

Side by side

Nano Banana 2.1 and Nano Banana 2, same prompt.

The same prompt at 2K on both models. Both get the words and the objects right; where they differ is layout, framing and detail.

A text-heavy poster

Both spelled every line correctly. Nano Banana 2 set the headline in the two condensed lines asked for, with the film titles in mixed case; Nano Banana 2.1 used three lines in a wider grotesque and kept the titles in capitals.

Nano Banana 2 result: the NIGHT SHIFT festival poster — Nano Banana 2

Prompt

Poster for an independent film festival. Top: a big bold grotesque headline "NIGHT SHIFT FILM FESTIVAL" in two lines, warm off-white. Middle: a photo of a young projectionist in a dark booth, lit by the projector beam, dust floating in the light. Bottom block: "NOVEMBER 6-9, 2026", "THE ORPHEUM, LISBON", then a row of four film titles separated by slashes: "Salt Lines / Paper Moons / The Last Tram / Kite Season", and a tiny footer "nightshiftfest.com". Deep plum #3B1E3F background, film grain, print-ready layout.

Nine objects in a grid

Both placed all nine objects in the right cells. Nano Banana 2.1 drew the laptop with a full, detailed keyboard.

Nano Banana 2 result: the nine-object desk — Nano Banana 2

Prompt

Top-down photo of a light oak desk. Exactly nine objects, placed like this: top-left corner a green ceramic mug of black coffee; top-center a closed red notebook with an elastic band; top-right a small succulent in a white pot; middle-left three yellow pencils lying parallel, points facing right; dead center an open silver laptop showing a blank white screen; middle-right a pair of round tortoiseshell glasses, folded; bottom-left a blue paper airplane; bottom-center a single orange tangerine with one leaf; bottom-right a brass key on a ring. Nothing else on the desk. No logos or brand names anywhere. Soft morning window light from the left, crisp shadows, editorial flat-lay photography.

An action photo

Both froze the cannonball and the spray. Nano Banana 2 framed it closer, from a low angle near the pier; Nano Banana 2.1 went wider, with the sun on the horizon and the jumper further out.

Nano Banana 2.1 result: friends jumping off a pier — Nano Banana 2.1

Nano Banana 2 result: friends jumping off a pier — Nano Banana 2

Prompt

Young friends jumping off a wooden pier into a lake at sunset, one of them caught mid-air in a cannonball, water spray frozen in the air, the others cheering on the pier. Shot from water level, 1/2000 s, warm backlight, natural color, real skin, candid.

Resolution

1K, 2K, 4K.

The same prompt at each tier, cropped to the same area around the eye. These are three separate renders, so the pose differs a little; what changes with the tier is how much skin, lash and droplet detail there is.

One close-up, three sizes

Draft at 1K, post at 2K, and use 4K when the picture will be cropped, printed or shown large.

Nano Banana 2.1 vs Nano Banana 2

Two models, different jobs.

Why this model

What Nano Banana 2.1 is for.

Follows the whole brief

Name nine objects and where each one goes, or four floors and what happens on each. It keeps the details of a long, layered prompt instead of dropping the small ones.

Text that reads

Menus with prices, packaging with small print, posters with a lineup, and signs in Latin, Japanese, Korean, Greek, Arabic, Cyrillic and Devanagari. Quote the words and they come out spelled as written.

One character, many scenes

Use a result as image 1 and move the same person somewhere new. Face, hair and small details like a beauty mark or earrings carry from turn to turn.

Three sizes, 4K for less

1K for 2 credits, 2K for 3, 4K for 4: the same sizes as Nano Banana 2, with 4K at 4 credits instead of 5. 1K and 2K are on the free plan.

Prompt guide

How to prompt Nano Banana 2.1.

Nano Banana 2.1 rewards a complete brief. Say what is in the picture, where each thing sits, the words in quotes, and the camera and the light.

The shape

Subject: who or what, doing what
Layout: where each element sits
Text: every word in quotes, in order
Details: counts, hex colors, conditions
Camera: lens, angle, shutter
Light: time of day and direction

A worked example

A still life on a dark slate table: five
glass jars in a row, filled left to right
with red lentils, yellow split peas, white
rice, black beans and green mung beans.
The third jar is the only one with its lid
off. A wooden spoon lies across jars four
and five only.

Name the positions

Top-left, center, bottom-right, ground floor, foreground: a place for each element is how a busy scene comes out arranged.

Quote the words

Every word that should appear goes in double quotes, in reading order. Words outside quotes are where mistakes happen.

Hex for colors

A code like #3B1E3F lands the exact color, on a background, a label or a product.

Bring a character back

Attach the earlier result as image 1 and say "the same woman from image 1", then name the features that must stay.

Say what stays

For an edit, describe the change, then list what should not move: the person, the room, the light, the angle.

Before you generate.

Last verified 6 Oct 2026

What is Nano Banana 2.1?

Google’s newest Gemini image model, released in October 2026 as a stable update to Nano Banana 2 (Gemini 3.1 Flash Image). Google describes it as keeping Flash-level speed and cost while bringing significant improvements in visual quality, prompt adherence, multi-turn character consistency and text rendering, and positions it as the faster, more efficient counterpart to Nano Banana Pro (Gemini 3 Pro Image). ReelyArt runs it server-side, so there is no Google account, API key or quota to manage.

Nano Banana 2.1 or Nano Banana 2?

Both render 1K, 2K and 4K, and both are on the free plan up to 2K. Reach for 2.1 when the prompt is long, the picture carries text, or a character has to come back in a new scene. In our side-by-side tests both spelled a poster correctly and placed nine objects in the right cells; they differed in layout and framing.

Can I use Nano Banana 2.1 for free?

Yes. A free account runs it at 1K (2 credits) and 2K (3 credits), so the 10 signup credits cover 5 images at 1K. 4K needs a paid plan. No card, no API key.

How many reference images can I attach?

Up to eight on a paid plan and four on the free plan, called image 1, image 2 and so on in the order you attached them: a person, products, a place or a style to borrow.

What does a Nano Banana 2.1 image cost?

2 credits at 1K, 3 at 2K and 4 at 4K, per image. Failed generations are refunded automatically.

How long does an image take?

About 15 seconds at 1K, 20 at 2K and 30 at 4K in our tests. Four variations run side by side, so they arrive at about the same time.
