Nano Banana 2.1What Is Nano Banana 2.1?
Nano Banana 2.1 is Google DeepMind's image generation and editing model, released as generally available on October 6, 2026. It is part of the Gemini 3 family and is built on Gemini 3.6 Flash; in the Gemini API its model ID is gemini-nano-banana-2.1. It replaces Nano Banana 2 (Gemini 3.1 Flash Image) on the fast Flash tier, while Nano Banana Pro (Gemini 3 Pro Image) remains Google's heavier model.
Google lists these gains over Nano Banana 2: better visual design and more natural-looking photos at 1K, 2K and 4K, sharper text and more accurate infographics, closer prompt adherence, subject consistency for up to 4 characters and 10 objects, mask-based editing, and no more tiling artifacts on very wide formats such as 4:1 and 8:1. It also has thinking levels and optional Google Search grounding, and Google cut its API image price by about half compared with Nano Banana 2.
Google rolled it out in the Gemini app, Google AI Studio, the Gemini API, Google Flow, Search AI Mode, Google Ads, Google Stitch and the Gemini Enterprise Agent Platform. On Seedance you can use it in the browser without an API key: text-to-image and image-to-image with up to 10 reference images, 1K, 2K or 4K output and 9 aspect ratios from 9:16 to 21:9, for 1, 2 or 3 credits per image. Every example on this page was generated with Nano Banana 2.1.
What's New in Nano Banana 2.1
Sharper Text and Infographics
Titles, labels and step captions come out spelled correctly and placed where you asked. That makes Nano Banana 2.1 practical for posters, explainers, menus and social graphics that used to need a designer to fix the lettering.
| Prompt | Nano Banana 2.1 output |
|---|---|
A clean editorial infographic poster titled "HOW COFFEE GETS TO YOUR CUP" in bold sans-serif at the top. Below it, five numbered steps in a vertical timeline with small flat illustrations and short captions: "1 Harvest", "2 Process", "3 Roast", "4 Grind", "5 Brew". Warm cream background, coffee-brown and orange palette, all text crisp and correctly spelled. |  |
Clean Wide and Panoramic Images
Nano Banana 2 could repeat patterns or show seams on very wide frames at high resolution. Google fixed these tiling artifacts in 2.1, so panoramic banners, website headers and wide landscapes hold together from edge to edge.
| Prompt | Nano Banana 2.1 output (21:9, 2K) |
|---|---|
Ultra-wide panoramic photograph of a mountain lake at sunrise, pine forest along the shore, mist on the water, snow-capped peaks reflected in the lake, one red canoe on the left, natural colors, no text, no watermark. |  |
More Realistic Photos up to 4K
Skin texture, fabric, light and depth of field look closer to a real camera. Use 4K for print, product pages and close-ups, and 1K for quick drafts at the lowest cost.
| Prompt | Nano Banana 2.1 output (4K) |
|---|---|
Photorealistic close-up portrait of an elderly fisherman with a weathered face and a grey knit beanie on a harbour at golden hour, shallow depth of field, visible skin texture and stubble, natural colors, shot on 85mm, no text. |  |
The Same Character in Every Scene
Give Nano Banana 2.1 one picture of a character and describe a new scene. The face, hair, glasses and outfit stay the same, which is what you need for comics, storyboards, brand mascots and a series of social posts.
| Reference | Prompt | Nano Banana 2.1 output |
|---|---|---|
 | Keep the same woman from the reference image (same face, curly red hair, round glasses, freckles, mustard-yellow raincoat). Show her walking across a rainy Tokyo street crossing at night with neon reflections on the wet road, holding a clear umbrella, photorealistic. |  |
| Keep the same woman from the reference image (same face, curly red hair, round glasses, freckles). She now sits by the window of a cozy café reading a book, mustard-yellow raincoat hung on the chair, soft morning light, photorealistic. |  |
Combine People and Products from Several Images
Upload a person, a product and a style reference, then say what goes where. On Seedance you can add up to 10 reference images to one Nano Banana 2.1 generation, enough for a full ad or lifestyle scene.
| Image 1 | Image 2 | Prompt | Nano Banana 2.1 output |
|---|---|---|---|
|  | Image 1 is a woman, image 2 is a water bottle. Create a lifestyle ad photo: the woman from image 1 hiking on a sunny mountain trail, holding the exact bottle from image 2 and smiling. Keep her face, hair, glasses and the bottle's color, shape and wooden cap unchanged. Natural light, photorealistic, no text. |  |
Text in Many Languages and Localized Designs
Google says Nano Banana 2.1 renders text well in 15 languages and can translate or localize the text already inside an image while keeping its style. Use it to adapt one poster, menu or ad for several markets: ask it to "translate all text to Spanish and keep the same layout". Small text and long paragraphs can still blur at 1K, so use 2K or 4K for dense layouts.
Thinking Levels, Search Grounding and Mask Editing
In Google's API, Nano Banana 2.1 can plan an image before drawing it (minimal, medium or high thinking), check real places and products with Google Search, and edit only a masked area. On Seedance the model runs with Google's default settings and you edit by describing the change in your prompt, which is enough for most background, outfit and object edits. For pixel-precise masks or search grounding, use Google AI Studio or the Gemini API.
