Seedream 3.0 is an advanced text-to-image model that can efficiently and quickly generate high-quality images from text prompts.
Currently, only the model version seedream-3-0-t2i-250415 is supported for Seedream 3.0.
Bearer authentication format: Bearer {{API Key}}.
Request Body
Text prompt for image generation.
The model ID or inference Endpoint ID used for this request. Currently only seedream-3-0-t2i-250415 is supported for Seedream 3.0.
Specifies the image format returned in the response. Default: url.
Supported values:
"url": Returns a downloadable JPEG image link.
"b64_json": Returns a base64-encoded image JSON string.
Specifies the size of the generated image (pixels, width x height), range is [512x512, 2048x2048]. Default: 1024x1024.
Recommended aspect ratios and resolutions:
1024x1024 (1:1)
864x1152 (3:4)
1152x864 (4:3)
1280x720 (16:9)
720x1280 (9:16)
832x1248 (2:3)
1248x832 (3:2)
1512x648 (21:9)
Seed value for controlling randomness in image generation. Range: [-1, 2147483647]. If not specified, one will be automatically generated. To reproduce the same result, use the same seed. Default: -1.
Controls how closely the output image matches the input prompt. Higher values give the model less freedom and produce stronger correlation with the prompt. Range: [1, 10]. Default: 2.5.
Whether to add a watermark to the generated image. Default: true.
false: No watermark added
true: Adds an “AI generated” watermark in the bottom-right corner of the image
Response
Array of generated image links. When response_format is set to "url", this array contains downloadable links for the generated images.
Array of Base64-encoded image data. When response_format is set to "b64_json", this array contains base64-encoded image JSON strings.
