When running diffusion models locally you often generate a lot of garbage. People with eight fingers per hand, cats with four tails, etc. When that happens you chalk that up to bad prompting or just the “magic” of image generation being too arcane to know.

When it comes to text, people don’t find “cats are an animal with four tails” an amusing statement in the same way that they do a drawing of one. The standard of acceptability is way higher.
