Gemini 3.1 Flash Image
The everyday Nano Banana model for serious image work
Nano Banana 2 is the balanced choice in the family: faster and more economical than Pro, but equipped for high-resolution delivery, reference-heavy edits, current information, and visual text.
One well-structured brief can carry the same subject, art direction, and finish across an entire visual system.
Search-grounded visual intelligence
Use web and image search grounding when a visual depends on current facts, recognizable places, products, or real-world context.
Up to 14 reference images
Combine subject, product, setting, material, lighting, style, and layout references in one generation. Give every image a clear role for cleaner results.
Stronger subject consistency
Keep characters, products, colors, and defining details recognizable as the pose, scene, crop, or format changes.
14 aspect ratios, from 1:8 to 8:1
Compose natively for social posts, covers, posters, banners, and extreme panoramic or vertical placements instead of relying on a late crop.
Reliable text and precise edits
Create stronger in-image typography, localize existing visuals, and follow detailed instructions about what should change—and what should not.
Nano Banana 2 use cases
Create a campaign, a sequence, or a complete set—not just one image
Choose Nano Banana 2 when you need several connected assets to share the same subject, product identity, or creative direction.
Product campaigns
Adapt one product campaign to new markets and scenes
Preserve shape, material, color, and label placement while changing the environment, crop, audience, or creative direction. Always proofread generated packaging copy.
Character continuity
Keep a recognizable character through every story beat
Anchor the face, wardrobe, props, and setting with clear references, then vary pose, framing, expression, and action without losing continuity.
Multi-format art direction
Design each format instead of cropping one master
Build an ultra-wide banner, square post, and tall poster around the same hierarchy while giving every canvas a deliberate composition.
How to use Nano Banana 2
Go from brief to usable image in four focused steps
The best results come from a clear deliverable, purposeful references, explicit constraints, and one review decision at a time.
01
Start from text or add references
Use a prompt for a fresh composition. Add images when a person, product, location, layout, or visual style needs to stay recognizable.
02
Tell the model what each image controls
Label references by job: identity, geometry, material, palette, lighting, camera angle, composition, or style.
03
Set the format and protect the essentials
Choose resolution and aspect ratio, then separate the requested changes from the details that must remain fixed. Put exact text in quotes.
04
Refine with narrow follow-up edits
Check identity, hands, geometry, small text, edges, and composition. Change one thing per round so you can judge the improvement clearly.
Nano Banana 2 prompt guide
Write a compact art-direction brief, not a list of adjectives
Name the deliverable first, connect each reference to a decision, describe the composition, and finish with the constraints that protect the result.
Multi-format campaign prompt example
DELIVERABLE — A premium travel campaign in three coordinated formats: 8:1 banner, 1:1 social post, and 1:4 poster. SCENE — Alpine lake at golden hour with the red canoe from @Image 1, the hiker from @Image 2, and the warm editorial grade from @Image 3. COMPOSITION — Recompose the subject hierarchy for each canvas; do not simply crop one image. Keep the canoe, hiker, mountain silhouette, light direction, and palette consistent. FINISH — Photorealistic, natural texture, crisp edges, restrained contrast. Leave clean copy space. No text, logos, watermarks, extra people, or duplicate canoes.
Lead with the deliverable
Say whether you need a product shot, storyboard, poster, banner, editorial image, or localized campaign asset.
Describe how the parts work together
Explain the relationship between the subject, camera, light, materials, environment, and every reference image.
Separate changes from locked details
For edits, name the one variable you want to change, then repeat the identity, geometry, pose, and framing that must stay fixed.
Quote and proofread every word
Provide exact copy in quotation marks, ask for it once, and verify every character before publishing the design.
