文生圖(Nano Banana 2/gemini-3.1-flash-image)——複雜指令與成品級畫質,每個檔位分別計價。 按實際交付張數計費,依圖片最長邊判檔(≤1024 px=1K、≤2048 px=2K、更大=4K)——模型的預設輸出可能落在比其總像素更高的檔位,且部分模型會忽略請求的尺寸。比照原廠牌價直通——無 ATP markup。生成失敗不計費。Preview:正式開放前費率可能調整。

全部是模型直接產出的原始結果,沒有後製。展開任一則就能看到完整提示詞。

提示詞
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.

提示詞
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.

提示詞
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.

提示詞
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.

提示詞
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.

提示詞
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.
適合場景
適合
- 需要清晰、在地化圖內文字的行銷 mockup、海報與廣告
- 使用極端長寬比、最高 4K 的橫幅、直式社群貼文與寬幅背景
- 從筆記或資料生成資訊圖表與示意圖
- 必須照字面精準呈現的複雜多段指令
通常較不適合
- 以最高事實準確度為首要的工作——Google 建議改用 Nano Banana Pro(ATP 上為 nano-banana-pro)
- 編修或改造既有圖片——請改用可傳入參考圖的 nano-banana-2-edit
