Stable Diffusion 2 uses OpenCLIP ViT-H model trained LAION dataset so it knows different things than the OpenAI ViT-L we're all used to prompting.
<br />This demo Convert a v1.x stable diffusion prompt to a stable diffusion 2.x prompt, by generating an image through RunwayML Stable Diffusion 1.5, then Interrogate the resulting image through CLIP Interrogator 2 to give you a Stable Diffusion 2 equivalent prompt.
