Seedream 4.0

Seedream 4.0 is ByteDance’s next-generation image creation model that combines text-to-image generation and image editing into a single architecture. It offers fast, high-resolution image generation, rich prompt understanding, and support for multi-reference and batch workflows.

Key Features

• Unified generation & editing
  Both text-to-image creation and image modifications (e.g. removing or replacing objects) are handled in one model—no need for separate tools.

• High-resolution and fast inference
  Produces outputs up to 4K with significantly faster inference than prior versions.

• Batch and multi-reference support
  Accepts multiple reference images and returns multiple outputs in one request.

• Natural-language prompt editing
  Make precise edits using simple language, like “Remove the boy in this picture” or “Replace this dog with a Schnauzer.”

• Versatile style transfer
  Apply diverse visual styles such as watercolor, cyberpunk, or architectural to inputs or prompts.

• Knowledge-driven generation
  Capable of complex content like educational illustrations, charts, timelines, or annotated scenes, with strong reasoning and prompt-following abilities.
