Shouldn't they be multiples of 8?
504x520 is a valid dimension in other SD pipelines.
The sd diffusion process run in the latent space of 1/8 of the width and height. In addition, unet will downsample the middle layer to 1/8 during the operation, so in fact the middle layer size will be 1/64 of width and height, which is why sd.cpp requires width and height to be multiples of 64.
If "sd" were to scale the latent space to a multiple of 8 before U-Net computation and then restore it to its original size afterward, it would indeed allow input widths and heights to be multiples of 8. However, I have not implemented it yet.

The height and width should be multiples of 64. I have updated the prompt for the command line parameters
