Seedream 4
Unified image generation and editing with high-resolution output and optional related image sets.
Unified image generation and editing with high-resolution output and optional related image sets.
Choose Seedream 4 when you want one node to move between prompt generation and reference-guided edits. Its main value in this group is breadth: 1K, 2K, 4K, or custom sizes, aspect-ratio matching, multiple reference images, and model-directed sequential image generation.
Sequential mode is useful for grouped exploration from one brief, but it is not a continuity lock. Review identity, small text, logos, and strict layouts before treating a result as final.
prompt
StringText prompt for image generation
Image Input
StringInput image(s) for image-to-image generation. List of 1-10 images for single or multi-reference generation.
Size
StringImage resolution: 1K (1024px), 2K (2048px), 4K (4096px), or 'custom' for specific dimensions.
2KWidth
NumberCustom image width (only used when size='custom'). Range: 1024-4096 pixels.
2048Height
NumberCustom image height (only used when size='custom'). Range: 1024-4096 pixels.
2048Prompt
StringText prompt for image generation
max_images
NumberMaximum number of images to generate when sequential_image_generation='auto'. Range: 1-15. Total images (input + generated) cannot exceed 15.
1aspect_ratio
StringImage aspect ratio. Only used when size is not 'custom'. Use 'match_input_image' to automatically match the input image's aspect ratio.
match_input_imagesequential_image_generation
StringGroup image generation mode. 'disabled' generates a single image. 'auto' lets the model decide whether to generate multiple related images (e.g., story scenes, character variations).
