AI Image
Quick decision
Use Lite when the job is clear and the output is 1K
Nano Banana 2 Lite is the compact lane in the Gemini image family. It works best when you know the subject, need a quick draft, and do not need large files or long edit chains.
Good fit: focused image edits
Upload an image when the request is narrow: change a background, adjust colors, simplify a product shot, or turn a subject into a sticker.
Use another model for heavy work
Move to Nano Banana 2 or Nano Banana Pro when you need 2K or 4K output, many references, strict brand consistency, or search-grounded factual visuals.
Why Lite exists
A faster Gemini image model for repeatable 1K work
Nano Banana 2 Lite is not the largest image model in the family. It is the practical model for quick, predictable outputs when 1024px is enough.
Sub-2-second target
Google describes Lite as aiming for under two seconds end-to-end latency, which suits interactive image tools and rapid prompt exploration.
Optimized for 1K
Lite supports 1024px output. It does not support 2K or 4K, so it is better for lightweight assets than final high-resolution production files.
Text plus image edits
The model accepts text and images as input and can return text plus images, so it can generate from prompts or make simple edits to uploaded visuals.
SynthID watermarking
Images generated by Gemini image models include SynthID watermarking. The DeepMind model page also notes C2PA support for Lite.
Nano Banana 2 Lite model details
The key facts below are compiled from Google DeepMind and Gemini API documentation updated in June 2026.
Model ID
gemini-3.1-flash-lite-image
Official name: Gemini 3.1 Flash Lite Image, also marketed as Nano Banana 2 Lite.
Speed target
Under 2 seconds
Google positions Lite as the fastest Gemini image model for high-volume developer and consumer use cases.
Output size
1024px / 1K only
The supported image_size value is 1024px. 2K and 4K output are not supported by Lite.
Aspect ratios
14 discrete ratios
Documented ratios include 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, and 21:9, plus standard formats exposed by the API.
Token limits
65,536 input / 4,096 output
The model supports text and image inputs, with image and text outputs. Knowledge cutoff is listed as January 2025.
Capabilities
Image generation, image editing, Batch API, function calling
It supports image generation and editing, Batch API, function calling, and thinking mode. It does not support caching, Live API, URL context, structured output, or search grounding.
Primary tradeoff
Not for complex reference or long edit chains
Google says Lite is not the right choice for multiple reference inputs or long multi-turn editing sequences.
How to use Nano Banana 2 Lite on this page
Use the prompt box when you need a fast draft or lightweight edit. For larger or more complex work, compare the related models below.
1
Write a precise prompt
Mention the subject, style, background, aspect ratio, and what should be excluded. Lite responds best to direct, compact instructions.
2
Pick Lite for 1K work
Use it for thumbnails, stickers, social variants, simple illustrations, and draft concepts where 1024px is enough.
3
Upload an image for edits
Ask for color swaps, background adjustments, simple cleanup, or sticker-style conversions. Keep edits focused.
4
Review before publishing
Check text, small faces, fine detail, data in charts, and localization. Use a higher-tier model when precision matters.
Prompting notes
How to get cleaner results from a Lite model
Lite works best when the prompt removes ambiguity. Treat it like a fast production assistant: give it a narrow brief, one visual direction, and a clear success check.
State format and ratio early
Write the intended use first, such as square sticker, 16:9 thumbnail, or vertical story image. Add the ratio even when the interface lets you choose one.
Keep the composition simple
Use one main subject, one background, and a short style phrase. Crowded scenes and many small objects make 1K results harder to review.
Separate edit requests
For uploaded images, ask for one or two changes at a time. Background swaps, color adjustments, and cleanup requests are easier than full scene rebuilds.
Avoid relying on tiny text
If the image needs labels, logos, or chart data, keep the text large and verify it after generation. For typography-heavy work, compare with another image model.
Model choice
When to choose Lite, Flash, or Pro
Nano Banana 2 Lite is the fast 1K lane. Nano Banana 2 is the general-purpose lane. Nano Banana Pro is for complex professional visual work.
| Need | Nano Banana 2 Lite | Nano Banana 2 | Nano Banana Pro |
|---|---|---|---|
| Fast 1K drafts | Best fit | Good but heavier | Usually unnecessary |
| 2K or 4K output | Not supported | Supports up to 4K | Supports pro-grade output |
| Many reference images | Avoid | Stronger fit | Best for complex references |
| Search-grounded images | Not supported | Supports web and image grounding | Supports advanced grounding |
| Simple uploaded-image edits | Best fit | Good fit | Use for strict detail control |
Known limitations to plan around
Lite is useful because it is focused. These limits help you decide when to move a task to Nano Banana 2 or Pro.
No 2K or 4K output
If you need large posters, print assets, or high-resolution product images, use Nano Banana 2 or Nano Banana Pro instead.
Complex edits can drift
Major lighting changes, heavy image blending, and long edit chains may introduce artifacts or mismatched details.
Small text and fine details need review
Google notes that Gemini image models can still struggle with tiny faces, spelling, and fine visual detail.
No Google Search grounding
Lite does not support search grounding, so factual graphics and current-event visuals should be checked or generated with a model that can ground results.
