Seedream AI
Seedream Image Generator
Seedream is ByteDance’s next-generation AI image generation and editing model that creates high-quality, bilingual visuals with remarkable speed, realism, and consistency.
Key Features of Seedream (v4 / v3)
Seedream is ByteDance's advanced image generation & editing model, combining high-quality output, bilingual support, and interactive editing capabilities.
Unified Generation & Editing
Seedream 4.0 merges text-to-image generation and image editing in a single model, enabling seamless transitions between creating new images and refining existing ones.
High Resolution & Speed
Produces native high-resolution outputs (1K to 4K) with fast inference (e.g. ~1.8 seconds for 2K) thanks to optimized architectures.
Multi-image & Reference Consistency
Supports multi-image batch generation, reference image inputs, and consistent character or object continuity across images.
Strong Text & Layout Capabilities
Handles textual elements, layout, typography and Chinese/English bilingual prompts with high fidelity, reducing artifacts in small text or structured layouts.
How to Use Seedream on story321.com
Follow these steps to try Seedream, adjust settings, and retrieve the generated images.
1
Select Seedream
On the Seedream model page, choose the version (v4 / v3) and mode (generation or editing).
2
Input Prompt & Settings
Enter your prompt, upload reference images if any, select resolution, aspect ratio, and other optional settings (e.g. style, layout).
3
Submit & Wait
Click 'Generate' or 'Edit' and wait for the inference process to complete (may take a few seconds).
4
Review & Iterate
Inspect output; if needed, refine your prompt or use editing mode for adjustments and re-generate.
Tips for Better Use
- •Use fewer ambiguity words (avoid beautiful, nice) and emphasize concrete visual attributes (e.g. golden light, reflective surfaces).
- •If you upload references, mask or annotate areas you want to keep vs change to guide the model.
For heavy usage, refer to rate limits, API quotas, and prompt usage guidelines documented on the model's detail page.
Use Cases for Seedream
Seedream fits a variety of creative, professional, and commercial applications across industries.
Concept Art & Illustration
Quickly generate visual concept sketches or polished illustrations for games, films, books, or storytelling.
Marketing & Advertising Visuals
Produce posters, banner images, social media creatives, and product visuals with strong layout and branding consistency.
Character Design & Visual Continuity
Generate or iterate characters with consistency across multiple views/scenes (e.g. for comics, animation).
Image Editing & Retouching
Use editing prompts to adjust background, replace elements, recolor areas, or clean up existing images.
Infographics, Layout & Poster Design
Create stylized posters or layouts with readable text, structured design, and visual flair.
Seedream FAQs
Frequently asked questions about Seedream model features, limitations, and usage.
What versions of Seedream exist?
There are multiple versions: Seedream 3.0 (text-to-image, bilingual) and Seedream 4.0 (unified generation + editing, multimodal).
What resolutions and speeds does it support?
Seedream 4.0 supports up to 4K native resolution and can generate a 2K image in ~1.8 seconds.
Can I edit an existing image, or only generate from scratch?
Yes — in version 4.0, you can give an image to edit (e.g. change background, recolor, replace elements) using natural language instructions.
Does Seedream support bilingual prompts?
Yes — especially in version 3.0 and onward, it supports both Chinese and English prompts natively.
How consistent are characters or objects across multiple outputs?
Seedream 4.0 supports reference consistency to maintain appearance, pose, and attributes of subjects across multiple generated images.
What are its limitations or challenges?
Some limitations include: very long or complex text inside images might degrade quality; occasionally ambiguous prompts yield unexpected layout; high-resolution images require more compute and consume more time.
Where can I find the technical report or model card?
The technical report for Seedream 3.0 is available on arXiv. For version 4.0, the arXiv preprint is also published.
Can I access Seedream via API or integrate it into my applications?
Yes — ByteDance / BytePlus offer API endpoints and integration options; you can access them via the model's detail page links.
