Nano Banana 2 model details
A practical guide to using Nano Banana 2 for Gemini 3.1 Flash Image generation, multi-reference editing, search-grounded visuals, and fast creative iteration.
Nano Banana 2 is the Flash-speed Nano path for briefs that need many references, 1K-4K output, broad aspect ratios, readable text, and optional search grounding. It is useful for moodboards, location-aware concepts, social campaigns, and rapid image testing.
What can I create with Nano Banana 2?
Nano Banana 2 works well for fast concept boards, factual visuals, location-inspired scenes, social graphics, product variants, and image edits. It is especially useful when a prompt needs speed, world context, and several references instead of one narrow source image.
- Moodboards and concepts
- Location-aware visuals
- Social media images
- Fast image edits
When should I turn on Google Search grounding?
Use search grounding when the image depends on real-world knowledge, such as landmarks, known products, places, trend references, or factual context. Keep it off for purely imaginative scenes where style and composition matter more than factual accuracy.
- Real places and objects
- Trend-aware visuals
- Less useful for fantasy scenes
- Pairs well with detailed prompts
How many references should I upload?
Nano Banana 2 supports up to 14 reference images, but more is not always better. Use multiple references to combine product shape, color palette, composition, and environment, then explain what role each reference should play.
- Up to 14 images
- Separate style and subject references
- Explain reference priority
- Avoid conflicting inputs
Nano Banana 2 vs Nano Banana Pro: what is different?
Nano Banana 2 is better for speed, search-aware context, ultra-wide or unusual ratios, and many references. Nano Banana Pro is better when you want a cleaner final image with stronger material detail, text placement, and fewer moving parts.
- Nano Banana 2 for breadth
- Pro for final polish
- Nano Banana 2 for search context
- Pro for premium detail
Which aspect ratio should I use?
Use auto when you want the model to choose naturally from the prompt. Pick exact ratios when the output is destined for a placement such as a product tile, thumbnail, mobile story, banner, or ultrawide landing-page visual.
- Auto for open-ended prompts
- 1:1 for catalog tiles
- 9:16 for stories
- 21:9 for wide hero images
