Seedream 5.0 Pro: FAQ

1. What is Seedream 5.0 Pro?

Seedream 5.0 Pro (ByteDance) is a high-end image model for text-to-image and reference-guided generation. Its standout is deep multi-reference support: up to 10 input images to guide subject, product, logo, style, or composition. It handles both creating new images and editing existing ones.

2. What resolutions does Seedream 5.0 Pro support?

• 1K (faster iteration)

• 2K (final-quality output, default)

3. What aspect ratios are available?

A wide range:

• 21:9, 16:9, 3:2, 4:3, 1:1, 3:4, 2:3, 9:16, 9:21

On edits, input dimensions are preserved.

4. Can you use reference images?

Yes, this is its core strength. Up to 10 reference images to guide subject, product, logo, style, or composition.

• Create: up to 10 references.

• Modify: 1 source plus up to 9 references (10 total).

When using two or more, identify each image's role in the prompt (subject, product, logo, style, or composition reference).

5. What output formats are available?

• JPEG (default)

• PNG (when lossless output matters)

6. Create vs Modify?

• Create Image (Seedream 5.0 Pro): generates a new image from a prompt, optionally reference-guided, with full aspect-ratio control.

• Modify Image (Seedream 5.0 Pro): edits an existing source image using up to 10 total input images, good for replacement subjects, products, or logos. Preserves the source's dimensions.

7. How does it relate to Seedream 4.0?

Seedream 4.0 is the specialty tier for niche art styles (retro anime, obscure aesthetics) with strong prompt adherence and up to 4K / 5 references. Seedream 5.0 Pro trades the 4K option for far deeper multi-reference control (up to 10 images) and caps at 2K, making it the stronger pick for brand, product, and composition-driven work.
