Unconscious Bias in Checkpoints - What No Prompts Reveal

2

This is a quick study to record a finding . . .

On a whim I decided to see what a checkpoint would render with no prompt entered either positive or negative.

In the past this had been tried and there were several articles (I can't remember where) about a ghostly anti-image lurking in the latent space of Ai Art. This was called LOAB.

I then decided to run a script which loaded each checkpoint and see what it generated, if the seed was fixed and there were no prompts either negative or positive.

The result was more surprising in that whilst there was some variation across checkpoints, in particular those skewed toward anime images, many results were more similar than I would have expected.
