Seedream 4.5 Text-to-Image: AI Image Generator Online
Bottom line
ByteDance's Seedream 4.5 generates at 4K with the layout-level prompt control the family is known for. Pick Seedream 4.5 Text-to-Image in the Text to Image tool, write your prompt, and pay per image in credits — the price is visible before you generate.
"Precise control" is an easy phrase to print on a spec sheet and a hard one to deliver, and it is the claim Seedream 4.5 stakes its listing on: prompts that specify layout, subject placement, and fine detail are meant to come back honored, at 4K output where those details actually survive scrutiny. For wallpapers, environment art, and any image someone will zoom into, generating at that size beats upscaling a smaller render.
Seedream is ByteDance's image-generation family — sibling to the Seedance video line — and 4.5 is its text-to-image entry on VdoBloom. It is a generator, not an editor: composition decisions happen in the prompt and the settings, with eight aspect ratios available from 1:1 and the 2:3/3:2 and 3:4/4:3 pairs through 9:16, 16:9, and 21:9.
The model holds a 4.5 user rating and carries VdoBloom's HOT content label, the platform's more permissive filtering class — worth knowing if strictly filtered models keep refusing prompts that seem defensible. Credit cost per generation is shown up front.
What creators use Seedream 4.5 Text-to-Image for

Frequently asked questions
What resolution does Seedream 4.5 generate at?
Its listing centers on 4K image generation, so outputs come back large enough for print-adjacent use and detailed crops without an external upscaling step.
Who is behind Seedream 4.5?
ByteDance. Seedream is its image-generation family — sibling to the Seedance video models — and 4.5 is the text-to-image entry from that line available on VdoBloom.
Does Seedream 4.5 support image editing?
No, this model is text-to-image only. Its eight aspect ratios (1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, 21:9) are set at generation time; for upload-and-edit workflows pick a generator-and-editor model instead.

It carries the HOT label, VdoBloom's more permissive and flexible filtering class. Baseline platform rules still apply, but it tolerates edgier creative prompts than strictly filtered models.
