Stable Diffusion v2 Cog model

There are two key differences between this and the stock Cog model:

1. The Safety Detector is deactivated
2. The service expects a callback URL where it will post every step of the diffusion

This is an implementation of the Diffusers Stable Diffusion v2.1 as a Cog model. Cog packages machine learning models as standard containers.

First, download the pre-trained weights:

cog run script/download-weights 

Then, you can run predictions:

cog predict -i prompt="monkey scuba diving"
