512x512 / 256x256
ドキュメントに512より小さくすると低品質になるとかいてある
Going below 512 might result in lower quality images.
Going over 512 in both directions will repeat image areas (global coherence is lost).
global cohernceって何？
The best way to create non-square images is to use 512 in one dimension, and a value larger than that in the other one.
なぜ？
The Stable-Diffusion-v-1-4 checkpoint was initialized with the weights of the Stable-Diffusion-v-1-2
checkpoint and subsequently fine-tuned on 225k steps at resolution 512x512 on "laion-aesthetics v2 5+" and 10% dropping of the text-conditioning to improve classifier-free guidance sampling.
もしかして小さいと小さい画像（アイコン）のようなものから学習したりするんだろうか？と思ったけどそう言うことではないのかな基素.icon
