# This is an abbreviated demonstration of how to perform this technique. The code
# is a simplified version of that in my own custom codebase, and can't be plugged
# into other ways of using Stable Diffusion (e.g. Diffusers or A1111) without changes.

# In essence, the observation that the CFG formula:
#
#     output_noise = uncond_noise + (cond_noise - uncond_noise) * scale
#
# looks a lot like the formula for the unsharp mask, a common way to sharpen or add local contrast to images:
