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.

The decisive moment: a Filipino man, early 20s, spiked black hair, wide exaggerated surprised expression, mouth open, slim build, wearing a bright red hoodie, pointing excitedly at something off-frame with wide eyes, against a punchy yellow gradient background with playful blurred confetti shapes. Close-up, eye level, 24mm lens, deep focus. Vibrant saturated ring-light glow, punchy high-contrast grade, extreme detail, photorealistic. Negative: blurry, distorted faces, extra fingers, warped text, oversaturated, watermark.

在 ATP 上

网关上的每个模型都套用同一套治理:

  • 项目 API 密钥——用量与撤销绑定单一项目
  • 模型白名单——仅启用的模型可被调用
  • 点数——1 USD = 100 点数,按完成请求扣款
  • 逐请求记录——模型、密钥、项目、点数可审计

成本试算

按刊例试算一个月的用量成本;实际扣款以每笔完成请求为准。
