SeedDream 4 rewrites the rules on what's possible with AI image generation. ByteDance's engineering prowess shines through in a model that generates 2K images in just 1.8 seconds, more than 10x faster than its predecessor. But speed isn't the only story here. SeedDream 4 also thinks before it draws, demonstrating impressive reasoning capabilities that help it solve visual puzzles, complete crosswords, and understand complex spatial relationships.
Blazing Fast Generation
1.8-second 2K generation and support for 4K ultra-high definition output when you need maximum detail.
Unified Generation and Editing
Both text-to-image creation and image modifications happen in one model. Virtual try-ons, object removal, background changes, and text removal all work seamlessly.
Visual Reasoning
The model doesn't just draw, it thinks. It can solve puzzles, complete crosswords, and understand complex visual relationships.
Multi-Reference Support
Accept multiple reference images and return multiple outputs in a single request for efficient batch workflows.
- E-commerce product variants and virtual try-ons
- Rapid creative iteration and concept exploration
- Educational illustrations and annotated diagrams
- Batch content generation for marketing campaigns
When you need volume without sacrificing quality, SeedDream 4 is unmatched. Its 12-billion parameter architecture captures context and style with precision, while its speed means you can explore dozens of variations in the time other models take to generate a few. The integrated editing capabilities eliminate the need for separate tools, keeping your entire creative workflow in one place.
