Main transformers use-cases and insights

Hi.

I’m very new to transformers and wanted some insight on some of the main and upcoming use-cases of transformers. I did research some cases but it’s mostly based GBT, Codex, etc. and I wanted to know of a few niche/different use-cases.

Also, examples of companies/industries/etc. (in Europe or GCC specifically) leveraging transformers would be nice to know. Something like a blog post or company profile.

If someone can help answer this, it would be great. Any references would be ideal.
