Why Altering the Resolution in Stable Diffusion Gives Strange Results

Stable Diffusion, originally designed for creating 512x512 pixel images, can technically produce images up to 2048x2048 pixels, but users often encounter issues when doing so. This is due to the software's method of generating larger images by creating multiple 512x512 "cells" that are independently influenced by the prompt and then stitched together, often resulting in disjointed and perspective-lacking compositions, particularly with human subjects. While non-discrete objects like fields can be rendered more seamlessly across cells, human figures may appear distorted or improperly segmented. The "Hi-res fix" option can mitigate these issues, though it requires significant resources. For those seeking guidance on best practices, joining the Runpod Discord is recommended.
