It takes 3 seconds to generate 1 image with my GPU.
I can find a good prompt within 30 minutes to 1 hour.
My GPU can generate 100 images in 5 minutes.
Out of those 100 images, 10 is very close to what I exactly meant at professional concept artist level.
So, in this case Stable Diffusion only working 10% of the time is fine.
Future is already here, I’m already incorporating stable diffusion generated images to my professional work.
