Why this model
What Seedream 4.5 is for.
The cheapest 4K on the site
4 credits for a genuine 4K render, half the price of Nano Banana Pro’s tier. For wallpapers and banners, this is the value pick.
Free at 2K
The 2-credit 2K tier sits on the free plan, so the high-resolution Seedream look costs a free account nothing extra.
A known quantity
A full generation of real-world use means its habits are documented and its outputs predictable. No surprises is a feature.
Two sizes, both honest
It skips the 1K rung entirely: 2K and 4K, each a real output size, covering exactly the large-format work it is kept around for.
Pricing

Credits per image; four variations cost four times the number shown. Aspect ratios: 1:1 · 16:9 · 9:16 · 4:3 · 3:4. Failed generations are refunded automatically. Plans and credit packs are on the pricing page.
FAQ
Before you generate.
Is Seedream 4.5 free to use?
The 2K tier (2 credits) is on the free plan. The 4K tier needs a paid plan, at 4 credits per image.
Why use 4.5 when Seedream 5 exists?
Price at size. Seedream 5 Pro tops out at 2K; 4.5 renders true 4K for 4 credits. When resolution is the point, the older model is the better deal.
Is the 4K real 4K?
Yes. ReelyArt only lists tiers a model natively renders, so the 4K tier returns genuine 4K pixels, not an upscale.
What is it best for?
Large-format output on a budget: desktop wallpapers, X headers, Discord banners and print-leaning artwork.
Does it take reference images?
Eight on a paid plan, four on the free plan, and every Studio template can run on it.
