Seedream 5.0 Pro supports 1K, 1.5K, and 2K resolution tiers, plus exact pixel sizes (e.g. 2048x1024). Exact pixel sizes are billed by actual output area: outputs of no more than 2,601,124 pixels use the 1K tier; larger outputs use the 2K tier. See the pricing details on this page for current prices and discounts. Generation is async—about 90s for 1K and ~160s for 2K—so poll seedream-5-0-pro tasks until complete.
