Overview

Seedream 4.5 is ByteDance's upgraded image generation model, an all-round scale-up of Seedream 4 focused on the parts of image generation that production work cares about most, prompt adherence, multi-image reference handling, dense text rendering, and identity continuity across edits. It runs text-to-image and image editing on a single architecture, so a multi-shot brand campaign or storyboard can stay inside one model from key still to final variations.

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.
