  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "bytedance/seedream-5.0-lite",
    "input": {
      "prompt": "Place the animal inside the vintage car",
      "image_urls": [

      ],

    }
  }'

max_sequential_images is the maximum number of sequential images the model may generate—not a fixed batch size. The model chooses how many to produce (from 1 up to that limit). Omit the parameter or set max_sequential_images to 1 for a single image. Sequential images are billed per image.

The number of URLs in image_urls reflects how many sequential images the model generated (up to your max_sequential_images ceiling).
