Visão geral
Sobre o 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.
