Gemini 3.1 Flash Lite Image

Turn one direction into more usable options, faster

Nano Banana 2 Lite targets sub-2 second end-to-end latency and lower generation cost. It supports interleaved image generation and editing, fast multi-turn local changes, strong character alignment, Thinking at minimal or high levels, and always-on SynthID watermarking with C2PA provenance.

Explore more directions early, then promote the strongest concept to a higher-resolution model when the deliverable demands it.

01

Sub-2 second latency target

Move quickly through prompt tests, composition options, color directions, and lightweight edits when turnaround is the primary constraint.

02

Cost-effective 1K output

Generate at 1024px for 4 credits per image. Nano Banana 2 Lite is optimized for 1K and does not produce 2K or 4K output.

03

Text-to-image and reference editing

Start from a prompt or guide the result with up to 10 JPEG, PNG, or WebP images, each up to 30 MB.

04

Auto plus 14 aspect ratios

Create formats from 1:8 and 1:4 through square, portrait, landscape, 4:1, 8:1, and 21:9 for more channels without a separate crop-first workflow.

05

Fast local and multi-turn edits

Swap colors, adjust backgrounds, create sticker-like assets, and iterate on a visual through focused conversational changes.

06

Character alignment and provenance

Maintain character alignment at original Nano Banana standards while always-on SynthID and C2PA provide embedded provenance signals.

Nano Banana 2 Lite use cases

Use speed and low credits where more options create value

Lite works best when the team needs many useful 1K directions before committing time and credits to a quality-first final.

Social formats

Recompose one campaign direction for every common canvas

Explore square, vertical, wide, and panoramic compositions around the same recognizable still life instead of forcing one crop to work everywhere.

Compare distinct visual directions before selecting a final route

Use low-credit generations to test styles, palettes, subjects, and composition logic, then carry the winning direction into Nano Banana 2 or Pro when higher resolution or grounding matters.

How to use Nano Banana 2 Lite

Keep the brief compact and the feedback loop fast

Choose the single decision you need to explore, give references clear jobs, lock the important details, and compare variants at 1K before escalating the final.

  1. 01

    Choose generation or an edit

    Start with text for a new visual, or add reference images when the subject, product, layout, material, or style should remain recognizable.

  2. 02

    Assign each reference one role

    State which image controls identity, shape, palette, lighting, composition, or style so the model can resolve the brief efficiently.

  3. 03

    Choose the delivery canvas

    Select auto or a specific ratio from 1:8 to 8:1 and compose for that format instead of relying on a destructive crop later.

  4. 04

    Change one variable per pass

    Test a focused change to color, background, material, framing, or style, then keep the strongest direction and move on.

Nano Banana 2 Lite prompt guide

Write a small brief that is easy to vary and compare

Name the asset, define the subject and canvas, link every reference to a decision, and separate the one requested change 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 deliverable

    Name a catalog image, thumbnail, social post, sticker, background edit, or style test so the model optimizes for a clear use.

  • Connect references to decisions

    Use explicit roles such as exact subject, product shape, lighting, color palette, composition, or visual style.

  • State the variable and the invariants

    Say what may change in this pass, then repeat the shape, identity, pose, material, or layout that must remain stable.

  • Use short comparison rounds

    Evaluate one controlled difference at a time so fast output produces a clear decision instead of a pile of unrelated images.
