Gemini 3.1 Flash Lite Image
Built for volume, experiments, and quick creative decisions
Nano Banana 2 Lite is the speed-and-value model in the family. It targets sub-2 second model latency, supports rapid generation and local edits, and keeps every output at a practical 1K resolution.
Explore widely at 1K, then move the winning direction to Nano Banana 2 or Pro only when the final needs more resolution or control.
1K output for 4 credits
Generate at 1K for 4 credits per image. Lite is optimized for efficient 1K work and does not offer 2K or 4K output.
Generate from text or edit with references
Start from a prompt or guide the result with up to 10 supported reference images.
14 aspect ratios plus auto
Compose directly for square, portrait, landscape, poster, banner, and panoramic placements—including 1:8, 1:4, 4:1, 8:1, and 21:9.
Fast, focused edits
Swap colors, adjust backgrounds, create sticker-style assets, and refine a visual through short, targeted changes.
Consistency with built-in provenance
Maintain recognizable characters across variations while always-on SynthID and C2PA add provenance signals to generated images.
Nano Banana 2 Lite use cases
Spend fewer credits where more options lead to better choices
Lite is made for the early and repeatable parts of creative work: product batches, channel variations, style tests, thumbnails, and quick edits.
Ecommerce batches
Build product-image batches without overspending
Keep the product recognizable while testing backgrounds, props, lighting, crops, and channel-specific art direction across a larger asset queue.
Social formats
Give every social canvas its own composition
Explore square, vertical, wide, and panoramic layouts around the same visual idea instead of forcing one crop to fit every channel.
Rapid ideation
Test more directions before choosing the final route
Compare styles, palettes, subjects, and composition ideas for fewer credits, then carry the winner into Nano Banana 2 or Pro when you need higher resolution or Search grounding.
How to use Nano Banana 2 Lite
Keep each round small, fast, and easy to compare
Choose one creative decision, give every reference a job, lock the essentials, and compare focused 1K variations before moving on.
01
Start fresh or bring a reference
Use text for a new visual, or add images when a subject, product, layout, material, or style needs to stay recognizable.
02
Give every reference one clear job
State which image controls identity, shape, palette, lighting, composition, or style instead of leaving the relationship open to guesswork.
03
Choose the canvas before generating
Select auto or a ratio from 1:8 to 8:1 so the composition is designed for the final placement instead of cropped afterward.
04
Change one variable at a time
Test a focused change to color, background, material, framing, or style. Keep the strongest option and use it as the next baseline.
Nano Banana 2 Lite prompt guide
Write a short brief built for fast comparison
Name the asset, define the canvas, connect each reference to a decision, and separate the current variable from the details that must stay fixed.
Fast ecommerce variation prompt example
DELIVERABLE — A coordinated set of 1K ecommerce product images in 1:1 format. REFERENCE — Use @Image 1 for the exact coral bottle. Preserve its silhouette, cap height, matte material, color, and proportions. VARIATION — Explore three simple studio directions: banana-yellow paper shapes, cyan frosted acrylic, and warm-white architectural blocks. Change only the set, props, crop, and light direction. FINISH — Clean product photography, crisp edges, believable contact shadow, generous padding. Blank bottle only; no labels, text, logos, hands, duplicate products, or watermark.
Ask for one clear deliverable
Name a catalog image, thumbnail, social post, sticker, background edit, or style test so the model can optimize for one purpose.
Link references to decisions
Assign explicit roles such as exact subject, product shape, lighting, color palette, composition, or visual style.
Name what changes and what stays fixed
Define the variable for this round, then repeat the shape, identity, pose, material, or layout that must remain stable.
Keep comparison rounds controlled
Evaluate one difference at a time so fast output leads to a clear choice instead of a pile of unrelated images.
