I was curious about the use of "sks" in the examples. It is explained in the paper: > Using DreamBooth [66], we fine-tune our Stable Diffusion spatial backbone on small sets of images of certain objects, tying their identity to a rare text token (“sks”). I wonder how long that token will stay "rare".
