Model Type:
Pricing: Seedream V4: 5 credits per image (~$0.025). The price is independent of image resolution and is solely determined by the final number of images returned. The number of images depends on the quantity specified in the prompt and the maximum value set by max_images, both of which jointly determine the final count. High-tier top-ups include +10% bonus credits. Effective pricing is approximately 10% lower than the above rates.
Input

The text prompt used to edit the image

0/5000

Click to upload or drag and drop

Supported formats: JPEG, PNG, WEBP Maximum file size: 30MB; Maximum files: 10

List of URLs of input images for editing. Presently, up to 10 image inputs are allowed.

The size of the generated image.

Final image resolution is determined by combining image_size (aspect ratio) and image_resolution (pixel scale). For example, choosing 4:3 + 4K gives 4096 × 3072px

Set this value (1–6) to cap how many images a single generation run can produce in one set—because they’re created in one shot rather than separate requests, you must also state the exact number you want in the prompt so both settings align.

Random seed to control the stochasticity of image generation.

A configurable parameter. Defaults to true in the Playground.

There is no guarantee that everything can be filtered out; if you are not satisfied with the results, you will need to make your own arrangements.
