Number of images to generateRange: 1-15 (minimum 1, maximum 15)Default: 1Note:
- Must enter a plain number (e.g.,
1), do not use quotes or it will cause an error
The number of reference images in
image_urls + the final number of images specified by n must be ≤ 15.Reference image URL list for image-to-image or image editingTwo formats are supported:1. Complete image URL
- Publicly accessible image URL (
http://orhttps://) - Example:
https://example.com/image.jpg
- Must use the complete Data URI format
- Format:
data:image/{format};base64,{base64 data} - Supported image formats: jpeg, png
- Example:
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABg... - Note: the
data:image/jpeg;base64,prefix is required
- Image formats: jpeg, png
- Aspect ratio (width/height) range: [1/3, 3]
- Width and height (px) > 14
- Size: not exceeding 10MB
- Total pixels: not exceeding 6000×6000 px
The number of reference images in
image_urls + the final number of images specified by n must be ≤ 15.Prompt optimization mode
standard: Standard mode, generates higher quality content with longer processing timefast: Fast mode, generates content in shorter time with regular quality
standardSequential image generation mode (Doubao-specific feature)Controls whether to generate multiple images:
disabled: Disable sequential mode, generates only 1 image even with multiple reference images (default)auto: Enable sequential mode, can generate multiple images
- ✅ Must provide
image_urls- at least 1 reference image required - ✅ Set
n: 3or usesequential_image_generation: "auto"+max_images: 3 - ✅ This will generate 3 different images based on reference images
- ⚠️ When
n > 1, it will automatically be set toauto
- Pure text-to-image (without
image_urls) cannot generate multiple images - this is a Doubao API limitation
Sequential image generation optionsAvailable when
sequential_image_generation is set to autoProperties:max_images(integer): Specify the number of images to generate, Range: 1-15
"sequential_image_generation": "auto",
"sequential_image_generation_options": {
"max_images": 3
}
Whether to add a watermark to the generated image
true: Add watermarkfalse: No watermark (default)
