The fastest Nano Banana
Nano Banana 2 is powered by Gemini 3.1 Flash Image — Google’s most efficient image generation model. It delivers approximately 4× faster generation than Nano Banana Pro at roughly half the cost, while maintaining high output quality. At 1K resolution, images generate in 5–15 seconds; 4K takes 15–40 seconds. The model integrates real-time web search grounding, enabling accurate rendering of current products, events, and entities without requiring detailed prompts..png?fit=max&auto=format&n=oPtF8B-1qLY-HQuK&q=85&s=da8d96827e3b8135afce8a70c37ff4cb)
Capabilities
Real-time web grounding
Integrated Google Search grounding renders current products, logos, and real-world entities accurately — no need to over-describe known subjects.
Up to 4K output
Supports resolutions from 512px up to 4096px on either axis, with flexible aspect ratios across standard and custom dimensions.
Text and data visualization
Accurate text rendering and data visualization capabilities — suitable for infographic drafts, labeled diagrams, and product callouts.

Prompting tips
- Use it for exploration first — Nano Banana 2’s speed makes it ideal for validating compositions before upgrading to Nano Banana Pro or ImagineArt 2.0 for final output.
- Reference images do the heavy lifting — Rather than describing every detail in text, pass reference images. The model excels at compositing from visual references.
- Let web grounding handle known subjects — For branded products, logos, or real-world locations, name them directly instead of describing them. The grounding handles the rest.
Example prompts
A sleek wireless speaker on a white marble surface, soft diffused studio lighting, product photography, crisp shadow.
A woman in a yellow raincoat standing on a mountain ridge, dramatic storm clouds, cinematic photography.
