Where Nano Banana 2 shines

Fast, high-fidelity image output

Nano Banana 2 is built for speed while still producing strong photoreal detail. Compared with lighter image models, it is better suited to polished hero images where lighting, texture, and realism matter.

4K-ready detail for serious assets

The model supports output tiers up to a 4K preview mode. That gives creators more room for campaign images, posters, and design drafts than 1K-only engines.

Edit by conversation, not rebuilds

Nano Banana 2 supports multi-turn edits and image-based prompting. You can revise regions, adjust the concept, and keep working from the same visual direction instead of regenerating from scratch each time.

Prompt guide

How to prompt Nano Banana 2

For Nano Banana 2, write prompts like a clear art brief, then use short follow-up edits to refine one thing at a time.

Build the prompt in 5 parts

Use Subject + Action + Setting + Style + Specs. Example: “A matte black smart speaker on a walnut desk, morning side light, premium tech ad style, 16:9, shallow depth of field, no text.”

Use chat edits for controlled changes

After the first image, ask for one change per turn: “Keep the product and camera angle. Make the background warmer and add soft window shadows.” This fits Nano Banana 2’s multi-turn editing strength.

Lock identity with references and seed

Use a reference image when a product, character, or style must stay consistent. Lock the seed, then change only one variable, such as lighting, crop, or background.

Suggested settings: 2K or 4K preview for final assets, fixed seed, 16:9 or 9:16, reference image on when identity matters.
