Features

ByteDance Seedream V3

Seedream V3 is ByteDance's latest text-to-image generation model, capable of creating high-quality, photorealistic images from textual descriptions.

Key Features

  • High-quality image generation
  • Photorealistic output
  • Fast synchronous inference
  • Stable and reliable

Input Requirements

  • Text prompt describing the desired image
  • Maximum prompt length: 2000 characters
  • Supports both Chinese and English prompts

Output

  • High-quality images with flexible resolution (512~2048)
  • URL format for easy access
  • Usage statistics included

Use Cases

  • Digital art creation
  • Content generation
  • Visual design
  • Creative inspiration

Limitations

  • Supported image sizes: 512~2048 pixels
  • Single image generation per request
  • Text-to-image only (no image-to-image or inpainting)

Out-of-Scope Use

This model should not be used for:

  • Generating harmful or misleading content
  • Creating copyrighted material without permission

Request Parameters

ParameterTypeRequiredDefaultRangeDescription
promptstringYes-The prompt to generate an image from.
sizestringNo1024*1024512 ~ 2048 per dimensionThe size of the generated image.
guidance_scalenumberNo2.50.0 ~ 20.0The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you.
seedintegerNo-1-1 ~ 2147483647 The same seed and the same prompt given to the same version of the model will output the same image every time.
enable_base64_outputbooleanNofalse-If enabled, the output will be encoded into a BASE64 string instead of a URL.
enable_sync_modebooleanNotrue-If set to true, the function will wait for the image to be generated and uploaded before returning the response. It allows you to get the image directly in the response. This property is only available through the API.
