<p style="text-align:center;">
Stable Diffusion 2 uses OpenCLIP ViT-H model trained on LAION dataset so it knows different things than the OpenAI ViT-L we're all used to prompting.
<br />This demo converts a v1.x stable diffusion prompt to a stable diffusion 2.x prompt, 
<br />by generating an image through <a href="https://huggingface.co/runwayml/stable-diffusion-v1-5" target="_blank">RunwayML Stable Diffusion 1.5</a>, then Interrogate the resulting image through <a href="https://huggingface.co/spaces/fffiloni/CLIP-Interrogator-2" target="_blank">CLIP Interrogator 2</a> to give you a Stable Diffusion 2 equivalent prompt.
