Gemini 3.1 Flash Image
Move from rough direction to production-ready imagery at Flash speed
Nano Banana 2 combines Flash-speed generation and editing with precise instruction following, real-time world knowledge, web and image search grounding, improved text rendering and localization, subject consistency, and richer textures.
Use one clear brief to coordinate subject, composition, format, and finish across a visual system.
Real-time world knowledge and grounding
Combine advanced world knowledge with real-time web information and image search grounding for current-event visuals, place-based concepts, infographics, and fact-aware content.
Up to 14 reference images
Assign each reference a job: subject identity, product geometry, material, setting, lighting, style, or composition. Fewer purposeful references usually outperform a crowded mood board.
Consistent characters and objects
Maintain consistency across up to five characters and preserve the visual details of up to 14 objects in one workflow for sequential stories and complete campaigns.
Expanded native aspect ratios
Create square, portrait, landscape, ultra-wide, and ultra-tall images, including 4:1, 1:4, 8:1, and 1:8 formats for banners, posters, covers, and campaign systems.
Improved text, localization, and instruction following
Render posters, mockups, and in-image copy more accurately, translate and localize visual content directly, and follow complex composition and editing requirements.
Nano Banana 2 use cases
Build a connected visual system, not just a single good image
Use reference-led generation when a product, character, setting, or campaign idea needs to remain recognizable while the context and format change.
Product campaigns
Keep product identity stable across markets and scenes
Hold shape, materials, cap, reflections, and label placement while exploring localized environments and new art direction. Proofread any generated packaging copy separately.
Character continuity
Develop sequential story beats around a recognizable subject
Use a clean identity reference and repeat the face, wardrobe, props, and environment details that must remain stable as pose, framing, and action evolve.
Multi-format art direction
Recompose one campaign for dramatically different canvases
Plan an ultra-wide banner, square post, and tall poster around the same subject hierarchy instead of merely cropping one master image after generation.
How to use Nano Banana 2
Give the model a clear visual job in four steps
A useful prompt defines the deliverable, names the reference roles, separates changes from invariants, and gives you concrete details to review.
01
Choose text-to-image or reference editing
Start with words for a new composition. Add images when identity, product shape, location, layout, or style must remain recognizable.
02
Assign every reference a purpose
Say which image controls the subject, material, palette, lighting, camera angle, or composition instead of asking the model to infer the relationship.
03
Define format, change, and invariants
Choose resolution and aspect ratio, then state what should change and what cannot change. Put literal text in quotes and specify its placement.
04
Review one decision at a time
Check subject identity, hands, product geometry, small text, edges, and composition. Make the next revision narrow enough to compare confidently.
Nano Banana 2 prompt guide
Write the prompt like a compact art-direction brief
Lead with the intended deliverable, describe the scene and subject, connect each reference to a decision, 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.
Name the deliverable first
State whether the result is a product shot, storyboard, poster, banner, editorial image, or localized campaign asset.
Describe relationships, not just objects
Explain how the subject, camera, light, materials, and reference images should work together in the final composition.
Separate changes from invariants
For edits, say change only the background or material, then repeat the identity, geometry, pose, and framing that must stay fixed.
Treat generated text as a draft
Provide exact copy in quotes, request it once, and verify every character before a design reaches production.
