What Nano Banana 2.1 Flash Can Do
Flash latency for drafts, up to 4K when you need delivery stills, and text that stays readable on posters and UI mocks.

Flash-Speed Text to Image
Generate catalog-ready stills quickly from a text brief—ideal when you need many options before lunch.

Image to Image Restyles That Keep Identity
Upload a subject and change wardrobe, season, or set while likeness and product silhouette stay locked.

1K Drafts to 4K Delivery
Work fast at lower res, then step up to 4K for hero frames without switching models.

On-Image Text That Stays Legible
Posters, packaging, and UI mocks with readable type instead of melted lettering.

Many References in One Pass
Bring character, product, and style refs together—up to around fourteen visual anchors when the brief is dense.

Broad Aspect Ratios for Every Channel
Square, story, widescreen, and print-friendly frames without awkward crops after the fact.
How to Use Nano Banana 2.1
Three steps from brief to a still you can ship:
01Start From Text or an Upload
Text to image for net-new frames; image to image when a photo or mock already exists.
02Add References and the Words That Must Appear
Attach character or product refs and spell any on-image text exactly as it should read.
03Pick Resolution and Iterate Fast
Draft at 1K, promote winners to 4K. Change one instruction per rerun.
What People Make With Nano Banana 2.1
Fast stills for ads, thumbnails, restyles, and type-heavy creatives.
Product Packshots With Readable Labels
Describe the bottle, pin lighting, and spell the brand line you need on the label. Raise to 4K only after the composition is right.
- Exact label copy — Type the words you need; do not paraphrase them.
- PNG for design handoff — Cleaner edges when the asset goes into a layout tool.

Social Stills in Native Ratios
Generate 9:16 for Stories, 1:1 for feed, 16:9 for headers — instead of cropping a square into every channel.
- Ratio before polish — Wrong frame wastes a good render.
- 1K drafts — Cheap iterations until the hook is clear.

Poster and Thumbnail Type
Nano Banana 2.1's text-rendering focus helps when a thumbnail needs three readable words rather than decorative squiggles.
- Short strings win — Three to six words stay legible more often than paragraphs.
- High contrast brief — Say light text on dark ground when contrast matters.

Restyle an Existing Shoot
Upload a photo and ask for a new backdrop, season or art direction without reshooting the talent.
- Upload first — The reference is the ground truth; the prompt is the delta.
- Change one axis — Backdrop or wardrobe — not both on the first edit.

How to Write Nano Banana 2.1 Prompts
Flash models reward concrete nouns: subject, light, lens feel, and any words that must appear on the frame.
A Nano Banana 2.1 still usually needs
- 1Subject — the object or person, with materials you care about
- 2Composition — camera distance, angle, and what sits in the background
- 3Lighting — window soft light, hard noon sun, studio softbox
- 4Exact on-image text — the literal words that must appear
- 5Output intent — poster, packshot, thumbnail, so framing stays purposeful

Matte ceramic mug on oak table, soft side window light, logo text "NORTH ROAST" in clean sans on the mug, shallow depth of field, 1:1 product still.
cyberpunk poster
Vertical poster of a rainy alley neon sign, bold headline "AFTER HOURS" centered upper third, deep teal and magenta, high contrast, 9:16.
make my photo better
