Seedream 4.0
Unified AI Engine for Generation, Editing, and Refinement
All-in-One Engine for Generation and Editing
Seedream 4.0 merges __image generation and image editing__ in a single architecture. You can generate new scenes from text, refine them with in-image edits, or apply precise local adjustments—all powered by the same model. This unified approach reduces hand-offs between tools and keeps visual quality consistent from first draft to final version.
High-Definition Output with Faster Inference
Designed for modern production needs, Seedream 4.0 delivers __high-definition images up to 4K__ with noticeably faster inference compared to previous versions. On Akool, that means you can iterate more often, test more creative directions, and still keep turnaround times short for campaigns, product detail pages, and social content.
Reference-Driven Consistency Across Campaigns
Seedream 4.0 is especially strong at __reference consistency__. It can leverage multiple reference images—such as brand packs, product shots, or character designs—to maintain identity, color, and style across many generations. This makes it a powerful choice for e-commerce catalogs, branded key visuals, and storytelling where the same character or product must look consistent from image to image.
