What's the difference between Seedream 4.5 and Seedream V4?

Seedream 4.5 offers enhanced image quality with better detail preservation, improved color accuracy, and more accurate prompt interpretation. It focuses on professional-grade output with streamlined 2K and 4K resolution options, while V4 offers 1K, 2K, and 4K options.

When should I use Seedream 4.5 instead of V4?

Use Seedream 4.5 for professional work requiring the highest quality output, when you need enhanced detail preservation, or when working on final production materials. Use V4 if you need the 1K option for budget considerations or quick iterations.

Does Seedream 4.5 support the same aspect ratios as V4?

Seedream 4.5 supports 8 aspect ratios (1:1, 3:2, 2:3, 4:3, 3:4, 16:9, 9:16, 21:9), which is similar to V4 but without the HD variants. All ratios use the standard format for consistent quality.

Can I use multiple images with Seedream 4.5?

Yes, Seedream 4.5 supports up to 10 input images per request, with enhanced multi-image composition capabilities. This is perfect for style transfer, reference-based generation, and complex image editing tasks.

Is the generation time longer than Seedream V4?

No, Seedream 4.5 maintains similar generation times (~40 seconds) despite the enhanced quality. This makes it efficient for professional workflows requiring high-quality output.

What resolution should I choose for print materials?

For most professional print applications, 2K (Basic) is sufficient. Choose 4K (High) for large-format prints, billboards, or when maximum detail is critical. Consider your final print size and viewing distance when deciding.

Nighttime outdoor photoshoot: A young man stands inside a public phone booth, holding a blue phone receiver to his ear. One hand is casually tucked into his pocket, and he strikes a relaxed posture. He wears a white T-shirt with a pattern, loose brown pants, and a jacket draped over his arm. The booth’s glass reflects city streetlights with a bokeh effect, creating a vintage film style.
