Social media content

Instagram-style lifestyle photo

Prompt: Square-format lifestyle photo for Instagram: a hand holding a ceramic cup of matcha latte with latte art, above a café table with an open paperback novel, a croissant on a small plate, and a wool sleeve visible, warm natural window light, cozy authentic tone, shallow depth of field, candid everyday aesthetic.

Product concept

Quick product concept

Prompt: Square product concept render of a compact desktop air purifier shaped like a smooth rounded cube in soft matte white, a thin glowing air-quality ring light on the front in gentle green, photographed on a light oak desk next to a small succulent, bright clean studio light, simple tech-catalog style with no text or logos.

Character concept

Prompt: Square character concept illustration of a friendly space-botanist: a young man with curly black hair, round amber goggles pushed up on his forehead, a patched olive flight jacket with seed packets in the pockets, holding a small glowing plant in a glass dome, soft painterly style with warm rim light, plain dusty-teal background, chest-up portrait.

Blog / editorial header

Fast blog header

Prompt: Wide 16:9 editorial illustration for an article about saving money on groceries: a shopping basket where the vegetables are also little piggy banks and coins, playful conceptual flat illustration, bold simple shapes, fresh palette of greens, coral, and cream, generous negative space on the left for a headline, subtle grain texture.

Realistic scene / stock-style photo

Everyday photoreal scene

Prompt: Wide-format realistic photo of a golden retriever puppy asleep in a ray of afternoon sun on a hardwood floor, one paw over a chewed tennis ball, dust motes in the light beam, shallow depth of field with a softly blurred living room behind, warm honest tones, natural pet photography.

Vertical ad / story format

Ad concept visual

Prompt: Tall 9:16 vertical ad concept for a fictional trail-running event: a lone runner on a mountain ridge trail at golden hour, dramatic clouds, winding path leading toward distant peaks, dynamic low angle, energetic warm grade, empty space in the upper third designed for overlay text later, no text rendered in the image, photorealistic sports photography.

What is Nano Banana built for?

Nano Banana is Google's lightweight text-to-image model, tuned for fast, prompt-faithful drafts rather than deep parameter control — the only setting on RenderFlow AI is PNG or JPEG output.

On RenderFlow AI it is the canvas to open first: test a concept at 5 credits, keep the winners, and only spend premium credits once the idea has proven it has a visual in it.

Why Nano Banana is the first canvas to open

Draft-speed generation — Nano Banana returns images fast enough that prompt testing feels like sketching, not rendering. A social team can try ten headline-visual pairings in the time a heavier model finishes two.

Few controls by design — With output format as the only dial, there is nothing to configure wrong and nothing to hide behind. All of your energy goes into the idea itself, which is exactly where early-stage work should spend it.

A reliable generalist — Products, characters, scenes, and simple graphics come back coherent on the first try more often than not. That makes it a dependable lie detector

A cheap filter ahead of premium models — Five credits per draft pays

A cheap filter ahead of premium models — Five credits per draft pays for itself by killing weak directions early. The prompts that win here graduate to Imagen 4 Ultra, Flux Pro Ultra, or GPT-Image-2 for the final file.

A four-pass Nano Banana ideation loop

Write the idea, not a spec

Keep the prompt to subject, action, and mood in one or two sentences. Nano Banana's job is to show you the shape of an idea fast; save lighting diagrams and lens notes for the premium re-render.

State the frame in words

There is no aspect-ratio control, so say "vertical story format" or "wide banner crop" directly in the prompt. Pick PNG for anything headed into a design tool, JPEG for quick shares.

Run a batch and mark the winners

Generate several variations back to back and keep only the compositions worth finishing. Five drafts cost 25 credits — less than one premium render spent on a weak idea.

Graduate the winner to a finishing model

Take the approved prompt to Imagen 4 Ultra, Flux Pro Ultra, or GPT-Image-2 and add the detail notes you deliberately skipped. Compare the two outputs side by side before publishing.

Frequently Asked Questions

What settings does Nano Banana have on RenderFlow AI?

Just one: output format, PNG or JPEG. There are no aspect-ratio or resolution dials, so describe the frame in words instead — "vertical phone wallpaper" or "wide YouTube thumbnail" — and the model composes to your description.

What is the difference between Nano Banana and Nano Banana 2?

Nano Banana 2 adds aspect-ratio control, resolutions up to 4K, stronger text rendering, and better character consistency at a higher credit cost. The original Nano Banana on this page stays the cheaper, simpler option for pure ideation speed.

Does Nano Banana render text in images?

Short words sometimes come out right, but it is not a typography model. When exact copy matters — posters, labels, ads — switch to GPT-Image-2, Seedream V4, or Qwen Image.

When should I move from Nano Banana to a premium model?

Once a draft's composition is approved and you need resolution, exact text, or fine detail. Re-run the winning prompt on Imagen 4 Ultra, Flux Pro Ultra, or GPT-Image-2 at Medium or High quality rather than asking Nano Banana for a finish it was not built for.

Can Nano Banana edit existing images?

This page is text-to-image only. For prompt-based edits to an existing photo or design, use the Nano Banana Edit page, which is the model's editing sibling.
