1. 人像摄影

创意时尚杂志：High-resolution studio portrait, close-up, retaining the reference image's model clothing, facial features, hairstyle, and glasses. White background with no identifiable elements. Her face is slightly turned, but her gaze is direct, intense, and focused. Her entire face is composed of puzzle pieces—each clearly visible with clean edges and a delicate 3D feel. She gently holds a piece she just removed from her cheek with her fingers, revealing a hollow black void underneath. Lighting is focused and directional, creating almost no shadows but accurately outlining the skin and the 3D puzzle structure. Overall atmosphere is surreal, precise, and highly realistic. Fashion magazine-style title "Atlas Cloud" at the top (behind the subject).

冬日氛围：Under a single lamppost, the man attached in the uploaded reference image ( Keep the face of the person 100% accurate from the reference image ) becomes a figure of solitude. The charcoal Dior Homme coat catches the warm glow of light as snow spirals through the dark. His scarf is wrapped high, Gucci gloves clutch the umbrella, and his gaze drifts upward toward the falling flakes. The surrounding night is blurred and dreamlike, a cinematic scene suspended between quiet introspection and timeless style.

专业设计 / 教育 / 图表

3D 玻璃 Logo：3D embossed glossy contour render of center-aligned [BRAND, the reference pic] on a flat surface, perfectly centered composition with ample negative space surrounding the object for a premium minimalist aesthetic. Monochromatic [Purple] palette with soft tonal gradients. The object is defined by a raised, smooth, liquid-like glass bezel or chrome rim, creating a blind emboss effect where the interior matches the background. Matte surface finish with fine film grain or noise texture overlay. Soft diffuse lighting, strong specular highlights on the rounded edges, top-down view.

20generate_response = requests.post(generate_url, headers=headers, json=data)
21generate_result = generate_response.json()
22prediction_id = generate_result["data"]["id"]
23
24# 第二步：轮询结果
25poll_url = f"https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}"
26
27def check_status():
28    while True:

33            print("生成的图片地址:", result["data"]["outputs"][0])
34            return result["data"]["outputs"][0]
35        elif result["data"]["status"] == "failed":
36            raise Exception(result["data"]["error"] or "Generation failed")
37        else:
38            # 仍在处理中，等待 2 秒
39            time.sleep(2)
