Isn't this a vanilla DDPM?

In Readme, it mentions this repo contains a stable diffusion implementation. But from the code, isn't it just a DDPM? Or did I miss anything?

I think the creator of this repo assumes the meaning of 'stable' in stable diffusion is that we can guide the results of the model by text(or classification). So, since the repo implemented this functionality, he claims that this repo contains an implementation of stable diffusion.
