Seedream 4.5 vs Seedream 5.0 Pro

Seedream 4.5 and Seedream 5.0 Pro differ on 3 specifications — from what each one costs to which inputs it accepts. Every value below is read from the live model catalog, so it stays current as new versions ship.

Which should you use?

Seedream 4.5 reaches 4K at a flat 6 credits; Seedream 5.0 Pro is the newer release but stops at 2K and costs 7 to 13. If output size matters, the older model is the one that delivers it.

This pairing is counterintuitive: the older model has the higher resolution ceiling. Seedream 4.5 covers 3K and 4K at a flat 6 credits. Seedream 5.0 Pro covers 1K and 2K, from 7 to 13.

So the version number does not tell you which to use. If anything is going to print, or gets cropped hard, or lands on a large display, Seedream 4.5 is the only one of the two that can supply the pixels — and it does so at a lower, flat price.

Seedream 5.0 Pro is the newer generation and the reason to choose it is output quality at the sizes it does cover, not capability. For web and social delivery at 1K or 2K that is a reasonable trade; for anything larger it is not a trade you can make.

Pick Seedream 4.5 when

  • You need 3K or 4K output — 5.0 Pro does not go past 2K.
  • You want flat, predictable pricing at 6 credits per image.

Pick Seedream 5.0 Pro when

  • 1K or 2K covers your delivery, which it does for most web use.
  • You want the current generation's output quality and are not size-constrained.
