### Request example

```json
{
  "modelId": "gpt-image-2-text-to-image",
  "input": {
    "prompt": "Create a high-end Japanese avant-garde couture fashion editorial photograph, 4:5 aspect ratio, featuring the woman from the reference image.\n\nKeep her face, identity, hairstyle, and overall appearance consistent with the reference image. Redesign only the outfit into a Japanese avant-garde couture style, inspired by traditional Japanese silhouettes, kimono construction, origami folds, layered fabric, asymmetrical forms, and contemporary Japanese architecture.\n\nThe outfit is highly sculptural and architectural, featuring dramatic geometric structures, exaggerated volumes, sharp folds, layered panels, and an innovative futuristic silhouette. Elegant yet unconventional, like wearable architecture. Do not use or reference any real fashion brands or copyrighted designs.\n\nPure black studio background. Add very subtle, translucent atmospheric smoke, softly drifting around the lower body and edges of the silhouette. The smoke should be thin, elegant, slightly hazy, and partially illuminated by the light, never obscuring the face or garment.\n\nUse one single hard key light only, creating dramatic highlights, deep shadows, and strong three-dimensional contours across the sculptural garment. High contrast, cinematic shadows, sophisticated Japanese noir atmosphere.\n\nAdd minimal editorial typography:\n“TOKYO NOIR”\nwith small secondary text:\n“BEYOND FORM”\n\nTypography should be elegant, minimalist, refined, and positioned like a luxury fashion magazine cover. No excessive text.\n\nUltra-realistic fashion photography, premium couture craftsmanship, detailed fabric texture, sophisticated composition, cinematic contrast, museum-like visual impact, luxury high-fashion magazine cover quality.\n\nNo logos, no real brand references, no watermark, no additional people.",
