参数一样，seed一样的话，1024x1024跟2048x2048的图，是一样的？高分辨率的图就是直接 resize 放大的吗？ QQ截图20240418110225 QQ截图20240418110330

The current demo is using 1024px checkpoint which is only used for generating 1024px images. Will release 2K checkpoint later. Plz stay tuned. Refer to: https://github.com/PixArt-alpha/PixArt-sigma#to-do-list
