Overview language models

Hello everyone,

I am desperate trying to find an overview over the most language models. I knew I found one in the past with a purple background, but I can’t find it anymore. Furthermore, I already try to get a lot of Information from the paper “Pre-trained Models for Natural Language Processing: A Survey” but not enough. I found one BERT-realted Overview but there is another one out there, and I need to find it! I would be happy if someone has an idea where I can find such an overview.

Thanks and regards
