Seedream 4.5 Text-to-Image: AI Image Generator Online
Bottom line
ByteDance's Seedream 4.5 generates at 4K with layout-level prompt control, flat 7 credits per image. 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's 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, launched 2025-12-03. It's a generator, not an editor: composition decisions happen in the prompt and settings, with eight aspect ratios from 1:1 through the 2:3/3:2 and 3:4/4:3 pairs to 9:16, 16:9, and 21:9.
It 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. Every generation costs a flat 7 credits, shown before you run it.
What it costs on VdoBloom
A flat 7 credits per generation, no resolution or aspect-ratio surcharge. Your 10 free signup credits cover one generation outright.
Seedream 4.5 vs Seedream 5 Lite vs GPT Image 2
Three different pricing models for three similar-tier generators. Seedream 4.5 and Seedream 5 Lite are both flat-rate (7 and 6 credits respectively) — 5 Lite is the newer, cheaper, slightly higher-rated option, and both cap at 4K. GPT Image 2 is resolution-tiered (3/5/8 credits), which is cheaper at 1K/2K but comparable at 4K. If you always generate at maximum resolution, the two Seedream models are simpler to budget for; if you frequently work at lower resolutions, GPT Image 2's tiering saves credits.
What creators use Seedream 4.5 Text-to-Image for
- 4K wallpapers and detailed environment art where fine texture matters at full zoom.
- Prompts that specify exact composition — subject placement, color palette, layout — and expect it honored.
- Cinematic 21:9 stills to storyboard a video project before committing to video generation.

Frequently asked questions
How much does Seedream 4.5 cost on VdoBloom?
A flat 7 credits per image, regardless of aspect ratio. Ten generations cost 70 credits.
Is Seedream 4.5 free to try?
New accounts get 10 free signup credits — enough for one 7-credit generation with 3 left over.
What resolution does Seedream 4.5 generate at?
Its output is 4K, 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, released 2025-12-03.
Does Seedream 4.5 support image editing?
Not this model — it's text-to-image only. For editing an existing image, use Seedream 4.5 Edit, which runs on the same engine and the same flat 7-credit price.
How permissive is Seedream 4.5's content filtering?
It carries VdoBloom's HOT label, the platform's more permissive filtering class. That means more creative latitude than strictly filtered models, not that any content is guaranteed to generate — baseline platform rules and provider limits still apply, and explicit content isn't promised.
Seedream 4.5 vs Seedream 5.0 Lite — which is better?
Seedream 5.0 Lite costs less (6 vs 7 credits), holds a slightly higher user rating (4.6 vs 4.5), and matches 4.5's 4K ceiling while also offering a 2K tier for lighter jobs. Seedream 4.5 remains a solid, proven choice if you're already standardized on it; for new work, 5 Lite is the cheaper option with comparable output.
Seedream 4.5 vs GPT Image 2 — how do the prices compare?
Seedream 4.5 is flat-rate: 7 credits regardless of resolution. GPT Image 2 is resolution-tiered: 3 credits at 1K, 5 at 2K, 8 at 4K. If you only need 1K or 2K output, GPT Image 2 is cheaper; if you always want the largest size, Seedream 4.5's flat rate is close to GPT Image 2's 4K price.
Can Seedream 4.5 generate NSFW content?
VdoBloom doesn't promise explicit output on any model. Seedream 4.5's HOT label means its content filtering is more permissive than stricter models on the platform, but generations are still subject to VdoBloom's platform-wide content rules.
