Nano Banana 2.1 is Google's update to Nano Banana 2, with better image quality, closer prompt adherence, cleaner text and steadier characters when you edit the same image over several turns. It renders at 1K, 2K and 4K and can combine up to 14 reference images, which makes it a strong choice for a series starring the same person, for posters and infographics, and for scenes built from several photos. Write in full sentences, give each reference image one job, and refine step by step. Choose Nano Banana 2.1 in the Luren AI image model list and paste any prompt below.
For a series, describe the character once in detail (face, hair, outfit and one signature accessory) and repeat that description word for word in every prompt.
Refine one change at a time, such as a new place or a new pose, and say each time that the face and outfit stay exactly the same.
Put every word you want rendered in quotation marks, and say where it sits and what the lettering looks like.
When you add several reference photos, number them in the prompt and give each a single role: the person, the outfit, the product or the room.
Use very wide and very tall shapes on purpose: name the format, such as an 8:1 banner or a 1:4 strip, and say what goes where along it.
A series starring you
01
Travel series: morning in Lisbon
Using my photo, show me on a steep tiled street in Lisbon in the morning, holding a paper cup of coffee, wearing a white linen shirt and a tan crossbody bag. Keep my face, hair and build exactly as in my photo. Soft natural light, candid travel-journal framing, 4:5 vertical.
02
Travel series: sunset viewpoint
Using my photo and the first image of this series as references, show the same me in the same white linen shirt and tan bag, sitting on a viewpoint wall above the river at sunset and laughing at something off camera. Keep my face and outfit identical; only the place, my pose and the light change.
03
Travel series: night tram
Using my photo and the earlier images of this series as references, show the same me in the same outfit riding a vintage yellow tram at night and looking out of the window as city lights streak past. Keep my face and clothing consistent with the earlier images and match their warm color grade.
04
Four-panel day in my life
Create a 2×2 grid from my photo showing one day in my life: making breakfast, working on a laptop in a café, cycling home along a canal, reading on the sofa at night. I must be clearly the same person in all four panels, with the same hair and the same navy sweater. Warm, natural editorial photography.
05
Me through the decades
Make a 2×2 grid of studio portraits of me from my photo as I might have been photographed in the 1950s, the 1970s, the 1990s and today, each with period-correct clothing, hair styling, film look and backdrop. My face must stay recognizable in every panel.
06
Matching profile pictures
Create three matching profile pictures from my photo, side by side: a professional headshot in a grey blazer, a relaxed outdoor portrait in a denim jacket, and a playful one against a bright yellow backdrop. Same face, same framing and the same quality of light in all three.
Posters, signs and infographics
07
Farmers market poster
A vertical 2:3 poster for a Saturday farmers market. The title "Fresh on Saturday" in large hand-painted green letters at the top, the line "8 AM to 1 PM · Harbour Square" beneath it, and an illustration of crates of tomatoes, peaches and leafy greens filling the lower half. Warm, sunny screen-print style.
08
Houseplant care infographic
An infographic titled "Keep Your Monstera Happy" with four panels in a 2×2 grid: Light, Water, Soil and Humidity. Each panel has a simple flat icon, a short bold heading and one sentence of practical advice. Off-white background, deep green and terracotta palette, generous margins, everything aligned to a clear grid.
09
Bookshop window lettering
A photo of a small bookshop window with white vinyl lettering that reads "Stories for Every Season" in an elegant serif, and a smaller line below it, "Open Late on Thursdays". Autumn leaves reflected in the glass, warm light and full shelves inside.
10
Conference schedule board
A 16:9 schedule board for a one-day design conference titled "Make Things Day". Five sessions in a single aligned column, each with a start time on the left and a session name in bold on the right, from "9:30 Welcome" to "16:00 Closing Talk". Modern sans-serif type, a single coral accent color, plenty of space between rows.
11
Translate my poster into Japanese
Translate every line of text on the poster in my image into Japanese. Keep the same layout, text hierarchy, colors and illustration, and choose a Japanese typeface that matches the weight and mood of the original lettering.
Blend several photos into one
12
Me, a new coat and a new city
Image 1 is me, image 2 is a camel wool coat and image 3 is a Paris street in the rain. Show me wearing the coat from image 2, walking down the street from image 3 under a black umbrella. Keep my face from image 1 and the exact cut and color of the coat.
13
Family photo from separate pictures
Combine the people in images 1 to 4 into one relaxed family photo around a garden table at golden hour. Keep each person's face, hairstyle and clothing faithful to their own photo, give everyone the same light and a believable scale, and make it look like a single candid shot.
14
Products on my desk
Place the headphones from image 2 and the notebook from image 3 on the wooden desk in image 1, next to the laptop that is already there. Match the desk's window light, add realistic contact shadows, and keep the products' shapes, colors and markings exact.
15
Moodboard to living room
Use images 1 to 5 as a moodboard: the sofa from image 1, the rug from image 2, the color palette of image 3, the plants from image 4 and the light of image 5. Design one calm living room that brings them all together, as a wide 16:9 interior photograph.
16
Me and my cat as explorers
Image 1 is me and image 2 is my cat. Create a storybook illustration of the two of us as explorers crossing a rope bridge over a jungle river, me holding a map and my cat riding in my backpack. Keep both of us recognizable, in a warm painterly style.
Wide and tall formats
17
8:1 website banner
An 8:1 panoramic website banner of a calm mountain lake at dawn, with mist rising off the water, pine forest along the shore and a single wooden canoe in the right third. Keep the left half quiet and simple so a headline can sit over it.
18
1:4 vertical scroll
A tall 1:4 illustration that reads from top to bottom like a hanging scroll: stars and a crescent moon at the top, then mountain peaks, a waterfall, a village of tiled roofs and finally a river with small boats at the bottom. Soft ink-and-wash style with touches of color.
19
4:1 garden timeline
A 4:1 horizontal timeline titled "A Day in the Garden" with six evenly spaced stops from sunrise to night, each with a small illustration and a one-word label: Dawn, Bees, Noon, Rain, Dusk, Moths. Clean flat style on a cream background.
20
21:9 beach shot of me
Using my photo, place me in the center of a 21:9 cinematic shot on a long, empty beach at low tide, with wet sand reflecting a pink and orange sky. I stand small in the frame looking out to sea, with my face and outfit unchanged.
21
Double exposure wallpaper
A 9:16 phone wallpaper made from my photo: me in profile, looking upward, as a soft double exposure with a starry night sky and a pine forest inside my silhouette. Keep my profile recognizable and leave clean space at the top for the clock.
Copy a prompt, open Luren AI, choose Nano Banana 2.1 in the model picker and paste it. Prompts that mention "my photo" expect you to add your own photo as a reference first.
Can I edit the prompts?
Yes, and you should: swap the setting, the outfit, the colours or the light for your own idea. Keep the order (subject, setting, light, camera, mood) and the model will follow you better.
Is Nano Banana 2.1 part of Luren AI?
Nano Banana 2.1 is made by Google. Luren AI is an independent app that gives you Nano Banana 2.1 together with other image and video models, so you can try the same prompt on several of them.
