inference.partner.seedream-4-5.txt2img.v2

View markdown

The inference.partner.seedream-4-5.txt2img.v2 job generates an image from a text prompt using Seedream 4.5.

{
  "type": "inference.partner.seedream-4-5.txt2img.v2",
  "config": {
    "prompt": "a serene mountain landscape at golden hour"
  }
}

Additional configuration:

  • width (number; default 2048)
  • height (number; default 2048)
  • watermark (boolean; default False)
  • seed (integer)

Supports resolution tiers instead of width/height, sequential generation with sequential_image_generation: "auto", and max_images. All successfully generated images are returned. Input and generated image counts together cannot exceed 15.
