🍌Nano Banana 2

Nano Banana 2 is Google's newest image generation + image editing model, officially named Gemini 3.1 Flash Image. It’s positioned as the "fast" upgrade path from Nano Banana Pro: similar high-fidelity output, but with much faster turnaround.

On SeaArt AI, you can think of Nano Banana 2 as a production-friendly visual engine: It's designed to help creators iterate quickly while still keeping strong prompt understanding and clean image quality.

❓What You Can Do with Nano Banana 2

1) Text-to-Image that "gets" complex prompts

Nano Banana 2 emphasizes deep prompt understanding and stronger reasoning for image tasks, which helps when prompts contain multiple constraints (subject + environment + materials + lighting + composition + story beats).

Good for

l Multi-subject scenes with clear relationships (who is doing what, where).

l Design-like requests (layout, product shot intent, clean compositions).

l "Explainable" visuals where details must match the description.

2) Fast, precise image editing (inpainting / outpainting / style changes)

Beyond generating from scratch, Nano Banana 2 supports advanced editing workflows—think targeted fixes, extending the canvas, or transforming the look—while keeping speed as a core advantage.

Use cases

l Repair hands/faces, remove objects, replace background elements.

l Expand a portrait into a full poster frame (outpainting).

l Restyle a scene while preserving structure (style transfer).

3) Output control that fits real deliverables

Nano Banana 2 supports control over aspect ratio and resolution, with upscaling from 512px up to 4K—useful when you're creating assets intended for publishing.

✅Why Pick It

Pro-level fidelity + Flash-speed iteration

Its headline positioning is a blend of high-quality results ("Pro-level intelligence and fidelity") with "lightning-fast speed," making it great for rapid creative loops.

Strong world knowledge + contextual accuracy

It's leveraging web search signals (real-time info + images) to produce outputs that are more contextually accurate—helpful for prompts that depend on current or specific real-world details.

Better price-performance for scale

Compared with earlier versions, it's positioned as more cost-effective.

🔔Prompting Tips That Work Especially Well

1. Write constraints as a checklist

l Subject (who/what)

l Scene (where)

l Composition (wide/close-up, angle, focal length feel)

l Lighting (softbox, golden hour, neon rim)

l Materials (metal, glass, fabric)

l Output (aspect ratio, resolution, "clean background")

2. For editing, describe the change—not the whole image

l "Replace the background with …"

l "Remove the object in the left hand…"

l "Extend canvas upward to show …"

This pairs naturally with inpainting/outpainting-style workflows.

3. When you need accuracy, add "what must stay the same"

l "Keep the face identity, keep the pose, keep the color palette—only change the outfit."
