Frequently Asked Questions

Compare Seedream 4.5's strengths, ideal use cases, supported controls, and tradeoffs before you generate.

What is Seedream 4.5 best at?

Seedream 4.5 is a high-resolution, reference-friendly image model with a polished commercial look. Its main advantage in this workspace is a production-oriented combination of up to 10 references, strong composition control, and output that starts at 2K and can scale to 4K.

Which projects suit Seedream 4.5?

Use it for advertising key art, cinematic product imagery, editorial fashion, detailed environments, posters, and reference-led campaign assets. It is especially useful when the final image needs rich texture, deliberate lighting, and enough resolution for large digital placements or further editing.

What inputs and output settings are supported?

The workspace accepts up to 10 reference images and offers 2K or 4K output. Available aspect ratios include square, portrait, landscape, vertical, and 21:9. References can separately define the subject, product, wardrobe, environment, palette, or composition.

How does Seedream 4.5 compare with Seedream 4?

Choose Seedream 4.5 when the deliverable is quality-led and will be produced at 2K or 4K. Seedream 4 is more flexible when you also need a lighter 1K output, while Nano Banana 2 is a better fit for very long prompts and larger reference sets during rapid iteration.

How should I prompt Seedream 4.5?

Start with the subject and action, then define framing, lens feel, lighting direction, materials, palette, and finish. If you upload several references, explain each image's job and identify the non-negotiable details. Avoid mixing several conflicting visual styles in the same request.

When should I choose another model?

Choose Seedream 4 for 1K drafts, Flux 2 Flex for typography-heavy layouts and fine text detail, or Midjourney when the goal is broad visual exploration rather than a reference-led production image.
