Nano Banana 2 is Google's Gemini 3.1 Flash Image, the Flash-tier image model of the Nano Banana family, announced in February 2026. Google says it brings much of Nano Banana Pro's quality to Flash speed, with clearer multilingual in-image text, stricter prompt following, 512 px to 4K output, and new 1:4, 4:1, 1:8 and 8:1 aspect ratios.

Text-to-image (Nano Banana 2 / gemini-3.1-flash-image) — complex prompts and final-quality renders; every tier is priced separately. Billed per delivered image at the tier of its longest side (≤1024 px = 1K, ≤2048 px = 2K, larger = 4K) — a model's default output can land in a higher tier than its pixel count suggests, and some models ignore the requested size. Passthrough of the model's official list price — no ATP markup. Failed generations are not billed. Preview: rates may change before general availability.

Nano Banana 2 demo · Sale banner backdrop, no text
Sale banner backdrop, no textCommercial
Prompt
An abstract commercial backdrop: smooth coral-to-amber gradient sweeping diagonally, with three soft-edged translucent geometric panes drifting across it and a subtle grain overlay. Deliberately empty on the left half so headline text can be placed there later. Wide shot, flat graphic composition, no perspective, even illumination with no hotspots, saturated but not neon, clean modern advertising grade, high detail. No lettering, no numbers, no logos anywhere in frame.
Nano Banana 2 demo · Data centre cold aisle
Data centre cold aisleCommercial
Prompt
A long cold aisle between two rows of black server racks, dense blue and white status LEDs receding into the distance, bundled cabling routed overhead, polished raised floor reflecting the light. No people. Wide shot with strong one-point perspective down the aisle, low angle just above floor level, 24mm lens, deep focus. Cool ambient LED glow as the only source with faint haze catching the light, desaturated blue-cyan grade with lifted blacks, extreme detail, photorealistic. No readable labels or logos.

Prompt
The decisive moment: a Brazilian woman, late 20s, glossy voluminous curls, radiant confident smile, slender build, wearing a fitted emerald green dress, holding up a sleek gold perfume bottle at chest height, light catching the glass facets, against a seamless emerald studio backdrop. Medium shot, eye level, 85mm lens, shallow depth of field. Bright even softbox lighting, clean high-key commercial grade, extreme detail, photorealistic. Negative: blurry, distorted faces, extra fingers, warped text, oversaturated, watermark.

Department storeComparison
Prompt
The decisive moment: a Japanese woman in her early 30s, a sleek chin-length bob with a soft side part, warm hazel eyes, a composed content smile with closed lips, slender upright posture, wearing a cream cashmere turtleneck under a tailored camel wool coat draped over one arm, a slim gold watch on her wrist, pausing mid-step in the atrium of a luxury department store, one gloved hand reaching toward a glowing glass display case of gift boxes, her gaze lifted toward the ornate glass-domed ceiling above. Warm holiday light spills from tiered crystal chandeliers; polished marble floors reflect rows of illuminated boutique storefronts; soft bokeh of distant shoppers recedes into the background. Wide shot composed with the domed ceiling's radial lines converging above her, low angle, 35mm lens, shallow depth of field with the storefronts falling into soft focus behind her. Warm tungsten chandelier light against cool marble reflections, honey-and-cream color grade, extreme detail, photorealistic. Negative: blurry, distorted faces, extra fingers, warped text, oversaturated, watermark, low resolution.

Prompt
The decisive moment: a Swedish woman, early 30s, platinum blonde pixie cut, piercing pale blue eyes, intense determined expression, athletic build, wearing a tactical dark grey jacket, standing amid drifting smoke in a rain-soaked alley, one hand gripping a flashlight raised beside her face, rain streaking through the beam of light. Medium shot, low angle, 35mm lens, deep focus. Low-key chiaroscuro lighting, high-contrast cinematic grade, extreme detail, photorealistic. Negative: blurry, distorted faces, extra fingers, warped text, oversaturated, watermark.

Shibuya crossingComparison
Prompt
The decisive moment: a Korean man, late 20s, sharp jaw, short side-parted black hair, warm brown eyes, calm smile, lean build, charcoal wool overcoat, open-collar white shirt and a Korean woman, mid-20s, wavy shoulder-length black hair, dark eyes, shy warm smile, petite build, red wool trench coat with a matching belt, small gold hoop earrings, mid-turn in a slow dance at Shibuya Crossing at night, hands clasped, facing each other, her coat caught mid-swirl. Pedestrians blur past behind them; unbranded billboards glow red, blue, white, no readable text; rain-slicked crosswalk reflects neon. Medium shot, eye level, 35mm lens, shallow depth of field, crowd and billboards in soft bokeh. Neon rim light on wet pavement, warm romantic cinematic grade, extreme detail, photorealistic. Negative: blurry, distorted faces, extra fingers, warped text, oversaturated, watermark.

Where it fits

Good fit
  • Marketing mockups, posters, and ads that need legible, localized in-image text
  • Banners, vertical social posts, and wide backdrops using extreme aspect ratios up to 4K
  • Infographics and diagrams generated from notes or data
  • Complex, multi-part prompts that must be rendered as written
Usually not ideal
  • Work where maximum factual accuracy matters most — Google points to Nano Banana Pro (nano-banana-pro on ATP)
  • Editing or restyling an existing image — use nano-banana-2-edit, which takes reference images
