How these prices were worked out
Credit costs are read from the same pricing engine that charges customers, so they cannot drift from what you are billed. Dollar figures divide each paid plan's price by the credits it includes, giving a low bound (the largest plan) and a high bound (the smallest). Image models are compared per generation, which is already a like-for-like unit. No figure on this page is estimated, and none of it describes what Seedream charges anywhere else.
What this page does not claim
Pixel Engine is not Seedream. It is a multi-model platform that runs Seedream’s models next to the alternatives on one credit balance. This page makes no claim about what Seedream costs on ByteDance’s own service, how fast it is there, or how its output compares — those are not things we can verify, so we do not publish them. If you need something only their own app provides, this is not a replacement for it.
Run the same prompt on each

Can I still use Seedream on Pixel Engine?
Yes. Seedream 4.5 is available on Pixel Engine from the same credit balance as every other model, so switching platform does not mean giving up Seedream.
What is the cheapest alternative to Seedream 4.5?
Flux Schnell, at roughly 67% less than Seedream 4.5 per generation on current plan rates. The full ranking is in the table above.
Is Flux Schnell as good as Seedream 4.5?
This page does not measure output quality — it publishes prices and capabilities, which are things that can be verified. The capability differences are listed above, and both models run from one account, so the practical answer is to send the same prompt to each and compare the results yourself.
Do I need a separate Seedream subscription?
Not for the models listed here. They run on Pixel Engine credits, so one balance covers Seedream and the alternatives rather than one subscription per vendor.
