Seedream 5

Seedream 5 accepts a text prompt for new images and optional image references for editing or style guidance. Pro configurations expose 1K and 2K output, while Lite is oriented around 2K and 3K output and includes separate generation and editing entries in this catalog. Up to ten references may be used, but fewer well-chosen images usually make each reference's purpose easier to communicate.

How to use this model

  1. 1

    Choose Pro or Lite and confirm that the selected entry matches generation or editing.

  2. 2

    Write the desired scene or edit as a precise prompt with subject, composition, lighting, palette, and required text.

  3. 3

    For editing, add only relevant reference images and explain what each one contributes.

  4. 4

    Select an aspect ratio, supported size, and output format before generation.

  5. 5

    Check text, subject identity, and small structural details, then refine the instruction instead of stacking contradictory prompts.

5.0 LiteAvailable

Seedream 5.0 Lite

Use Seedream 5.0 Lite without references to generate an image from text, or attach one or more references to edit, combine, or restyle them. The native BytePlus model supports one output at 2K, 3K, or 4K and up to fourteen references; the application selects the mode from the supplied inputs.

Properties

  • One model for text-to-image generation and image editing.
  • Native BytePlus supports 2K, 3K, and 4K output with up to fourteen references.

Best for

  • Text-to-image generation and reference-guided editing without switching models

Tips

  • Leave references empty for text-to-image generation; add them to edit or compose from images.

How to use this model

  1. 1

    For text-to-image generation, leave Reference Images empty and describe the subject, composition, lighting, palette, and style.

  2. 2

    For editing, attach the source and only the references needed, then state both the requested change and what must remain unchanged.

  3. 3

    Choose the output resolution, aspect ratio, and JPEG or PNG format.

  4. 4

    Refer to multiple inputs by their order when assigning different roles to them.

  5. 5

    Review identity, layout, visible text, and edit boundaries at full size.

5.0 ProAvailable

Seedream 5.0 Pro

Seedream 5.0 Pro supports precise text-to-image generation, multilingual text rendering, editing with up to ten references, and position-aware visual changes using coordinates, selection boxes, or arrows.

Properties

  • Supports text to image workflows.
  • Supports image to image workflows.

Best for

  • High-precision image generation and editing
  • Multi-reference composition with up to ten images
  • Position-aware edits described with coordinates, boxes, or arrows

Avoid for

  • Batch or streaming generation, outputs above 2K, or WebP output

Tips

  • Use only the references needed for the edit; the first is free and each additional reference is billed separately.
  • Fast prompt optimization reduces latency at the cost of some generation quality.

How to use this model

  1. 1

    Describe the subject, composition, lighting, and style you want.

  2. 2

    Choose an aspect ratio and output size for the intended placement.

  3. 3

    Generate, review the result, then refine the description or add references.
