Seedream 4.0 Core Features
Unified Generation & Editing
Seedream 4.0's single architecture handles both text-to-image creation and image modifications in one integrated model. This eliminates the need to switch between different tools for generation versus editing, creating a seamless workflow. The model maintains consistent quality and style whether you're creating from scratch or modifying existing images.
4K Ultra HD Resolution
Produce professional-quality images up to 4K resolution with enhanced detail preservation. The advanced architecture delivers significantly higher resolution outputs than standard AI image generators while maintaining fast processing speeds of under 1.8 seconds for 2K images.
Natural Language Editing
Make precise edits using simple, intuitive language commands. Whether you need to remove objects ('Delete the person in the background'), modify elements ('Change the dress color to blue'), or completely transform scenes ('Make this look like a watercolor painting'), Seedream 4.0 understands and executes complex instructions accurately.
Batch Processing & Multi-Reference
Process multiple reference images simultaneously and generate batches of outputs in single requests. This powerful feature enables efficient production of marketing campaigns, storyboards, and creative projects requiring consistent style across multiple images, dramatically improving workflow efficiency.
Versatile Style Transfer
Apply diverse visual styles including watercolor, cyberpunk, architectural, and more to any input image or text prompt. The style transfer capabilities maintain image integrity while transforming the aesthetic to match professional design requirements or creative visions.
Knowledge-Driven Generation
Create complex, information-rich content like educational illustrations, technical diagrams, timelines, and annotated scenes. Seedream 4.0's advanced reasoning capabilities understand context and generate intelligent visuals that accurately represent concepts and relationships.
Seedream 4.0 Use Cases
Marketing Campaign Creation
Creative agencies use Seedream 4.0 to develop entire marketing campaigns with consistent visual style across all materials. The batch processing feature generates multiple concept variations simultaneously, while the style transfer ensures brand consistency. Marketing directors report cutting campaign development time by 60% while achieving higher-quality results.
Educational Material Development
Educators and instructional designers leverage the knowledge-driven generation to produce accurate diagrams, timelines, and annotated illustrations. The AI's reasoning capabilities create complex educational visuals that clearly communicate concepts, reducing production time for teaching materials while improving quality and accuracy.
Product Design Prototyping
Design teams rapidly iterate product concepts using natural language commands to modify colors, styles, and configurations. The ultra-fast generation allows for quick testing of multiple design variations, accelerating the prototyping phase while maintaining high-quality visual outputs for stakeholder review.
Social Media Content Production
Content creators generate engaging visual content in seconds, from stylized portraits to imaginative scenes. The 4K resolution ensures social media posts maintain quality across all platforms, while the batch processing feature enables creation of content calendars worth of images in minimal time.
How to Use Seedream 4.0
Upload your image by dragging and dropping a file (JPEG, PNG, or WebP up to 5MB) or click to browse your device. The platform supports various aspect ratios including 1:1, 4:3, 3:4, 16:9, and 9:16 to match your project requirements.
Enter your editing or creation prompt in natural language. Describe exactly what you want to modify ('Remove the background'), generate ('Create a cyberpunk cityscape'), or transform ('Make this portrait look like a Renaissance painting'). The AI understands complex, multi-part instructions.
Configure output settings including number of variations (1-4 images per generation) and resolution preferences. For batch processing, you can upload multiple reference images at this stage.
Click 'Generate' and receive your ultra-fast results. High-quality 2K images typically appear in under 1.8 seconds, while 4K outputs take slightly longer but maintain the same exceptional quality and detail preservation.
Review, download, or make additional refinements. The intuitive interface allows for quick iterations - simply adjust your prompt and regenerate until you achieve perfect results.
