文生图(Nano Banana 2/gemini-3.1-flash-image)——复杂指令与成品级画质,每个档位分别计价。 按实际交付张数计费,依图片最长边判档(≤1024 px=1K、≤2048 px=2K、更大=4K)——模型的默认输出可能落在比其总像素更高的档位,且部分模型会忽略请求的尺寸。比照原厂牌价直通——无 ATP markup。生成失败不计费。Preview:正式开放前费率可能调整。

提示词
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.

提示词
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.

提示词
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.

提示词
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.

提示词
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.

提示词
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.
适合场景
适合
- 需要清晰、本地化图内文字的营销 mockup、海报与广告
- 使用极端宽高比、最高 4K 的横幅、竖版社交帖子与宽幅背景
- 从笔记或数据生成信息图与示意图
- 必须照字面精准呈现的复杂多段指令
通常较不适合
- 以最高事实准确度为首要的工作——Google 建议改用 Nano Banana Pro(ATP 上为 nano-banana-pro)
- 编辑或改造已有图片——请改用可传入参考图的 nano-banana-2-edit
