What is Seedream

Seedream is a commercial-grade AI image generation and editing model family by ByteDance (Volcano Engine / Doubao). The latest version 5.0 Lite delivers an optimized balance of speed and quality with native 3K output, while version 4.5 pushes the quality ceiling with native 4K output (up to 4096×4096). Built on a unified DiT architecture with integrated generation and editing, all versions support text-to-image and image-to-image without model switching. Core features include character/brand consistency across images, high-precision text-image layout, and ultra-fast generation — purpose-built for advertising, e-commerce, design and other commercial scenarios.

Character/brand consistency (biggest breakthrough): Up to 10 reference images to lock facial features, clothing, and brand identity across scenes — zero face-swapping for the same model in different poses and settings, enabling serialized mass production

Precise instruction following: 65% improvement in instruction accuracy (4.5 vs 4.0) with 87% comprehension of professional art terminology, built-in physics/spatial engine for perspective, occlusion, lighting, and material refraction

High-precision text-image layout: Clear Chinese and English text rendering without garbled characters or stroke blending, auto-formatting fonts, colors, layouts, and logo integration for production-ready posters and banners

Frequently Asked Questions

What's the difference between 5.0 Lite, 4.5, and 4.0?

5.0 Lite is the latest version optimized for speed and balanced quality, supporting 2K/3K output. Version 4.5 delivers the highest quality with native 4K output (4096×4096), character/brand consistency, and 65% better instruction accuracy over 4.0. Version 4.0 is the classic edition for cost-effective production.

How does character/brand consistency work?

Upload up to 10 reference images, and Seedream precisely locks facial features, clothing details, and brand identity elements across scenes. The same model maintains high consistency across different scenes and poses, solving AI's 'split personality' problem and enabling serialized mass production.

What resolutions are supported?

Resolution tiers vary by version: 5.0 Lite supports 2K and 3K, while 4.5 and 4.0 support 2K and 4K. You can also specify exact pixel dimensions (WxH format) for precise control. In smart mode, the model automatically determines the optimal aspect ratio based on your prompt.

How good is the text-image layout?

Seedream supports high-precision Chinese and English text rendering without garbled characters or stroke blending. It automatically formats fonts, colors, layouts, and logo integration, supporting calligraphy, seal script, formulas, and complex layouts for production-ready posters and banners.

Can the generated images be used commercially?

Yes. Content generated by Seedream includes full commercial licensing and can be used directly for advertising, e-commerce, marketing materials, and other commercial scenarios without purchasing additional licenses.
