Access

You searched Gemini Flash Image. In our picker it is Nano Banana 2

Google's Gemini API docs list Nano Banana 2 as Gemini 3.1 Flash Image and call it the generalist workhorse of the family. So you are in the right place: Kavel runs that model in your browser on credits, with no AI Studio quota, Cloud billing or key. The weights are private, so there is nothing to download.

Three things Gemini Flash Image does best, according to its users

Words inside the image you can read

Words inside the image you can read

"Text and infographics: yes, the model can do them now, letters are no longer garbled," one r/Bard tester reported. This monstera plate carries a title, a Latin name and three labels.

  • Put the exact words in quotes: 'ANATOMY OF THE MONSTERA PLANT'
  • Name the lettering: serif title, hand-drawn labels
  • Keep each label to two or three words
Photo detail that holds up at 4K

Photo detail that holds up at 4K

"Nano Banana 2 looks like a photograph taken with a high-end DSLR," an r/GeminiAI reply said of Gemini Flash Image. This portrait was posted from a 4K test: every wrinkle and grey strand.

  • Give the lens and light: 85mm, overcast daylight
  • Ask for texture by name: weathered skin, wind-blown hair
  • Render the keeper at 4K for 45 credits

A creator drew two comic chapters on Gemini Flash Image, "heavily relying on references" to hold characters steady. The same idea gives icon sets: this mailbox matches the padlock above.

  • Lock the material words: pink tinted glass, soft studio light
  • Change only the object between runs
  • Upload the first result as the style reference for the next

A steam railway on a floating island

A steam railway on a floating island

@artingent

Terrain, buildings, workers, a plaque with a heading, then camera and render style.

A whimsical floating miniature world depicting a steam railway cliff station built on a rugged mountain terrain island suspended above vast cloud-filled valleys.  The floating terrain island reveals fractured granite cliffs with exposed geological strata and alpine vegetation. A narrow mountain stream flows through the terrain before spilling as a waterfall over the island edge.  At the center of the settlement sits a compact cliffside railway station where a steam locomotive waits beside a wooden platform. Surrounding structures include a mechanical signal tower controlling rail traffic, a steam engine maintenance shed, a cargo depot, and a small workshop repairing brass railway components.  Engineers inspect the locomotive while workers load crates onto rail carts.  Architecture features polished brass fittings, exposed gears, steam pipes, and riveted iron machinery characteristic of Steampunk engineering.  An ornate brass plaque is mounted beside the railway platform.  Heading — Steam Railway Cliff Station 

Style — Steampunk Description — A dramatic cliffside railway hub where steam locomotives navigate dangerous mountain tracks high above the clouds.  Three-quarter isometric perspective showing the entire floating terrain island and exposed rock underside.  High-poly 3D environment render, cinematic lighting, global illumination, physically based materials, ultra detailed miniature environment, AAA game environment art, Unreal Engine style render, volumetric lighting, depth of field.  The terrain floats freely with no pedestal, no display base, and no support structure.

A flower power poster with a slogan

A flower power poster with a slogan

@minuitIA

The slogan in quotes first, then era, colours, symbols and print texture.

Create a vintage 1960s–1970s flower power poster with the slogan “MAKE LOVE NOT WAR” as the main focus. Use a psychedelic hippie aesthetic, colorful floral patterns, peace symbols, warm sunset tones, retro typography, groovy shapes, and a dreamy, optimistic atmosphere. The poster should feel like an anti-war peace movement artwork from the Woodstock era, with vibrant pink, orange, yellow, purple, and teal colors. Add flowers, hearts, doves, and subtle vintage texture. Bold, artistic composition, nostalgic screen-printed poster style, highly detailed, visually striking.

Gemini Flash Image vs the rest of Google's image family

Google's naming is where people get lost. Each name, what it is, where to run it.

Gemini Flash Image vs Nano Banana 2

The same model. Nano Banana 2 is the product name, Gemini 3.1 Flash Image the API name. One reply summed up the confusion.

Google product naming is a disaster

Open the Nano Banana 2 page

Gemini Flash Image vs Gemini 3 Pro Image

Pro is Nano Banana Pro. On Kavel, Flash also edits your photos, which Pro here does not, and a 1K image costs two thirds of Pro's credits.

See Gemini 3 Pro Image

Gemini Flash Image vs Gemini 3.1 Flash Lite Image

Lite is Nano Banana 2 Lite, which your free credits run. Google's docs say Flash excels at multiple reference images, while Lite is not optimized for multiple references or multi-turn editing.

Gemini Flash Image vs Gemini 2.5 Flash Image

Searching the older name? Gemini 2.5 Flash Image is the first Nano Banana, which Google now calls its legacy model.
