# Nano Banana image generator > A Nano Banana image generator is a tool that runs Google's Nano Banana image model: you type what you want and it returns a finished picture. On Kenerate AI it runs Nano Banana 2.1, which Google released on 6 October 2026, in Image Studio: text to image or up to 14 reference images, 14 aspect ratios and 1K, 2K or 4K output, with optional web search. An image costs 21 credits at 1K.

Open Nano Banana 2.1 — Go to Image Studio with Nano Banana 2.1 selected (kenerateai.com/app/image?model=nano-banana-2.1). Any one-time credit pack unlocks it. 2. Describe the image — Type the prompt. To keep a face, product or character, add up to 14 reference images and say what each one is. 3. Pick ratio, size and web search — Choose one of 14 aspect ratios, 1K, 2K or 4K, and switch on web search if the picture needs real-world facts. 4. Generate and download — Press generate, then download the image with no visible watermark or keep editing it. ## In depth ### Text to image or reference images? With text alone, Nano Banana 2.1 invents everything from the prompt — fine for posters, infographics, landscapes and product ideas. When something has to look like a real face, a product you sell or a character you already designed, attach it: Google's docs allow up to 14 reference images in one request [1][4], and Kenerate passes all 14 through. Name each reference in the prompt ('image 1 is the bottle, image 2 is the label') and list what must not change. That is how the library scene and the movie poster above kept the character and the face. ### What changed in Nano Banana 2.1 Google calls 2.1 its "latest image generation and editing model", with leaps in visual design, mask-based editing and subject consistency [2]. The Gemini API docs describe it as an update to Nano Banana 2 with better quality across 1K, 2K and 4K, fixed tiling on wide and panoramic ratios, and better text rendering and infographic layout [1]. For the full model comparison with Nano Banana 2 and Pro, see the Nano Banana 2.1 model page. ### When to use a different generator Nano Banana 2.1 is the pick when consistency matters — the same face, product or character across shots. For long, dense text and logos many users start with GPT Image 2.5 Sunburst; for illustration and anime at a lower cost, Seedream 5.0 Pro. All of them sit in the same Image Studio, so you can run one prompt on two models and keep the better image. ### About the examples The twelve text-only images are unretouched Nano Banana 2.1 outputs made on 7 October 2026 for our Nano Banana pages. The library scene (one anime design as reference) and THE LOST TRAIL poster (one AI-made test photo as reference) are Nano Banana 2.1 outputs first published on our OC maker and movie poster pages. No new images were generated for this page. ### The 14 example images (all Nano Banana 2.1) Unretouched outputs; the model and setting are named on each line. - Golden-hour portrait (Nano Banana 2.1, 2K): "Close-up portrait of a young woman with freckles and copper hair in golden-hour backlight, shallow depth of field, natural skin texture, 85mm photo" — https://storage.kenerateai.com/seo/ig/nbp-portrait.webp - Perfume product shot (Nano Banana 2.1, 2K): "Luxury perfume bottle on a wet black marble slab, single orchid, dramatic rim light, droplets, high-end product photography" — https://storage.kenerateai.com/seo/ig/nbp-product.webp - Jazz festival poster (Nano Banana 2.1, 2K): "Retro jazz festival poster with the title 'BLUE NOTE NIGHTS' in big art-deco letters, a saxophone silhouette, navy and gold, screen-print texture" — https://storage.kenerateai.com/seo/ig/nbp-poster.webp - Web search: solar system (Nano Banana 2.1, 1K): "Accurate infographic of the eight planets of the solar system in order from the Sun, each labelled with its name, clean white background, educational poster" — https://storage.kenerateai.com/seo/ig/nb21-web.webp - Anime rooftop key visual (Nano Banana 2.1, 2K): "Anime key visual of a girl on a rooftop at sunset over a city, wind in her hair, cherry petals, cinematic Makoto Shinkai lighting" — https://storage.kenerateai.com/seo/ig/nbp-anime.webp - Scandinavian living room (Nano Banana 2.1, 2K): "Scandinavian living room with a low oak sofa, linen textures, large window with snowy forest view, warm lamps, architectural digest photo" — https://storage.kenerateai.com/seo/ig/nbp-interior.webp - Pancake food photo (Nano Banana 2.1, 2K): "Overhead food photo of a stack of fluffy pancakes with blueberries, maple syrup drip and powdered sugar on a linen table, morning light" — https://storage.kenerateai.com/seo/ig/nbp-food.webp - Floating castle landscape (Nano Banana 2.1, 2K): "Epic fantasy landscape: a floating castle above a waterfall canyon at sunrise, dragons in the distance, volumetric light, matte painting" — https://storage.kenerateai.com/seo/ig/nbp-fantasy.webp - 4:1 sale banner (Nano Banana 2.1, 2K): "Wide website banner for a summer sale: the words 'SUMMER SALE — 40% OFF' in bold white letters on the left, sunglasses, a beach ball and a surfboard on bright yellow sand on the right, clean flat lay photo" — https://storage.kenerateai.com/seo/ig/nb21-banner.webp - Collectible figurine (Nano Banana 2.1, 2K): "Collectible 1/7 scale figurine of a girl astronaut on a round acrylic base on a computer desk, figure box with illustration behind it, realistic product photo" — https://storage.kenerateai.com/seo/ig/nbp-figurine.webp - YouTube thumbnail (Nano Banana 2.1, 1K): "YouTube thumbnail: a shocked young man pointing at a giant glowing golden trophy, bold yellow text 'I WON!' on the left, high contrast, bright background" — https://storage.kenerateai.com/seo/ig/nbp-thumbnail.webp - Watercolor fox (Nano Banana 2.1, 1K): "Loose watercolor painting of a fox curled up asleep under autumn leaves, soft washes, paper texture, muted orange and teal" — https://storage.kenerateai.com/seo/ig/nbp-watercolor.webp - Same character, new scene (Nano Banana 2.1 · 1 reference image, 1K): "Put this same original character in a new scene: the red-haired sorceress sits at a wooden desk in a cosy candlelit library at night, reading an old spellbook, a small glowing blue orb floating above the page.

A: It's any tool that runs Google's Nano Banana image model to turn a written prompt into a picture. Google's newest version is Nano Banana 2.1 (model ID gemini-nano-banana-2.1), released on 6 October 2026. On Kenerate AI you use it in Image Studio: type a prompt, optionally add reference images, choose a ratio and size, and generate. Q: How do I generate images with Nano Banana? A: Open kenerateai.com/app/image?model=nano-banana-2.1, write what you want — for example "Overhead food photo of a stack of fluffy pancakes with blueberries, maple syrup drip and powdered sugar on a linen table, morning light" — pick an aspect ratio and 1K, 2K or 4K, and press generate. Every example on this page shows the exact prompt that made it. Q: Is the Nano Banana image generator free? A: Not on Kenerate: Nano Banana models are not on the free plan and unlock with any one-time credit pack, after which a 1K image costs 21 credits (31.5 at 2K, 42 at 4K). The 25 free sign-up credits work on the free-plan models such as Qwen Image 3.0 and Flux 2. Google offers Nano Banana in the Gemini app within usage limits. Our Nano Banana free page compares every option. Q: Can Nano Banana make images from my own photos? A: Yes. Nano Banana 2.1 takes up to 14 reference images per prompt, on Kenerate and in Google's docs. Attach the photo, say what to keep ("same face, same curly hair") and describe the new picture — the poster on this page was made that way from one photo. To change an existing photo rather than make a new one, see the Nano Banana image editor. Q: What sizes and aspect ratios does Nano Banana 2.1 make? A: On Kenerate: 1K, 2K or 4K, in 14 aspect ratios — 1:1, 4:5, 3:4, 2:3, 9:16, 1:4, 1:8, 5:4, 4:3, 3:2, 16:9, 21:9, 4:1 and 8:1. Google's docs list 1K, 2K and 4K for 2.1 and say it fixed tiling artifacts on wide and panoramic ratios. Q: Can Nano Banana put readable text in images? A: Usually, if the text is short and quoted. Google says 2.1 improved text rendering and infographic layout, and the titles on the poster, infographic and thumbnail examples here are legible and spelled right. Nano Banana also likes to add lines you didn't ask for (the jazz poster gained a subtitle and a footer), so end the prompt with "no other text". Long paragraphs and tiny labels can still break, so proofread before you publish. Q: Do Nano Banana images have a watermark? A: Kenerate adds no visible watermark. Google states that all images its Nano Banana models generate include SynthID, an invisible digital watermark that identifies them as AI-made. Q: What is web search in the Nano Banana generator? A: An optional switch that lets Nano Banana 2.1 look things up with Google Search before drawing, so facts in the picture are more likely to be right. Our solar-system infographic used it. It adds 4.2 credits per image on Kenerate. Q: Nano Banana 2.1 vs the Nano Banana in Gemini — what's the difference? A: Same model family, different app. Google's Gemini app gives image generation with Nano Banana 2 to users without a paid plan at standard limits (Google's limits page, as we checked on 23 October 2026). Kenerate runs Nano Banana 2.1 with the ratio, resolution, reference and web-search controls exposed, pay-per-image with credits that never expire. ## Related pages - Nano Banana 2.1: https://kenerateai.com/model/nano-banana-2.1 - Nano Banana prompts: https://kenerateai.com/nano-banana-prompts - Nano Banana prompt generator: https://kenerateai.com/nano-banana-prompt-generator - Nano Banana image editor: https://kenerateai.com/nano-banana-image-editor - Nano Banana video generator: https://kenerateai.com/nano-banana-video-generator - Is Nano Banana free?: https://kenerateai.com/nano-banana-free - Nano Banana 2: https://kenerateai.com/model/nano-banana-2 - AI image generator: https://kenerateai.com/ai-image-generator ## Sources - Google AI for Developers — Gemini API docs: Nano Banana 2.1 (gemini-nano-banana-2.1): https://ai.google.dev/gemini-api/docs/models/gemini-nano-banana-2.1 - Google on X — "Meet Nano Banana 2.1" (6 Oct 2026): https://x.com/Google/status/2107501209154204148 - Google — Nano Banana 2 announcement (the model 2.1 updates): https://blog.google/innovation-and-ai/technology/ai/nano-banana-2/ - Google AI for Developers — Gemini API: Nano Banana image generation (read 31 Oct 2026): https://ai.google.dev/gemini-api/docs/image-generation
