FAQs

What is Seedream 4.5?
Seedream 4.5 is ByteDance's upgraded image generation model. It improves prompt adherence, multi-image reference handling, and dense text rendering while keeping text-to-image and editing unified in a single model.
How is Seedream 4.5 different from Seedream 4?
ByteDance positions 4.5 as an all-round improvement through overall scaling of the model, sharper detail preservation across multi-image references, enhanced typography and dense text rendering, and designer-level composition. Use 4.5 when identity continuity or typography in the image matters.
Does Seedream 4.5 support multi-image input?
Yes. You can pass in multiple reference images, the model identifies the main subject in each and composes a coherent output that preserves the important details from every reference.
How do I use Seedream 4.5 on Morphic?
Open Copilot, attach your references, describe the result, and pick Seedream 4.5. It's a strong default for brand series, poster work, and any prompt where the same subject needs to appear consistently across multiple images.
Can I edit images with Seedream 4.5?
Yes. The same model handles both text-to-image and image editing, so you can generate a base, then refine with targeted edits in the same conversation.
When should I pick Seedream 4.5 vs Seedream 5.0?
Use Seedream 4.5 when you want fast, high-fidelity multi-image composition and clean text rendering. Use Seedream 5.0 when you need the model to reason carefully, pull in current real-world context, or learn from example-based edits.
