GPT Image 2.5 4K and Transparent Background — Quality That Scales
GPT Image 2.5 4K generation produces images suitable for large-format print, retina displays, and professional product catalogs. Resolution is a single click (1K, 2K, 4K), and credit cost scales with quality — 1 credit for 1K, 2 for 2K, 3 for 4K — so you only pay more when you need more pixels.
Note that the 27:16, 16:27, 9:8, and 8:9 aspect ratios support 1K resolution only; 2K and 4K are available for all other ratios. When generating transparent backgrounds at 2K or 4K, include an instruction describing an isolated subject for the cleanest cutout.
