Questions

Seedream 4.5 FAQ

Why is 4K the same price as 2K?
Flat pricing on this tier. Render at 4K every time, because dropping to 2K saves nothing at all.
Is there a 1K option?
No. This model starts at 2K, which is the point of it: its floor is where other models put their ceiling.
How many images per run?
Up to 8, and at these sizes a full batch of large images is unusually good value.
How many references?
Up to 4 per run, used to hold a campaign set in one consistent look.
Seedream 4.5 or 5 Pro?
4.5 when you want size and value, since both of its tiers are priced the same. 5 Pro when someone will look at the image closely.
