What inputs does it need?

A text prompt is all you need for text-to-image. To use image-to-image mode, attach up to 10 reference images, which switch the model from its default text-to-image behavior.

What resolutions and aspect ratios are available?

You can render at 2K or 4K and choose from eight aspect ratios: 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, and 21:9. Outputs are delivered as PNG or JPG.

Can I explore multiple options at once?

Yes. You can generate up to 8 prompt variations in a single request to compare different directions quickly.

How do I run it on HexGen?

Open Seedream 4.5 in HexGen, enter your prompt, pick your resolution and aspect ratio, optionally attach reference images, and generate. Results return as downloadable PNG or JPG files.

Informazioni su Seedream v4.5

Seedream 4.5 is ByteDance's image model in the Seedream family, available on HexGen for both text-to-image generation and reference-guided editing. Write a prompt and it produces a fresh image; attach reference images and it switches to image-to-image mode, using your shots as visual guidance.

Pick the output you need: render at 2K or 4K, and choose from eight aspect ratios spanning square, portrait, landscape, and ultrawide 21:9. You can request up to 10 reference images per job and generate as many as 8 prompt variations in a single request, so exploring a concept stays quick.

Pricing is flat per image with no resolution, quality, or duration multipliers, so the cost stays predictable whether you render at 2K or 4K. Outputs come back as PNG or JPG, ready to download.
