I have already asked a similar question [here](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Fpegasus-questions%2F838%2F29) but I guess this is actually the correct section to ask 🙂 .

I need to use a pre-trained Pegasus which is not fine-tuned on downstream datasets. It seems that this model only exists in its large configuration, am I correct? Is there any way to get an equivalent base model?  
As for the distilled models, what is the difference between a distill-\* and a student-\* model? And what do the two numbers represent (e.g. in sshleifer/distill-pegasus-cnn-16-4)?
