There is a typo at the end of line [37](https://github.com/huggingface/course/blob/726835943d7d2158135efeb36731d06182ea15b5/chapters/en/chapter1/4.mdx?plain=1#L37C1-L38C172) and line [38](https://github.com/huggingface/course/blob/726835943d7d2158135efeb36731d06182ea15b5/chapters/en/chapter1/4.mdx?plain=1#L38) should come before [48](https://github.com/huggingface/course/blob/726835943d7d2158135efeb36731d06182ea15b5/chapters/en/chapter1/4.mdx?plain=1#L48)

This list is far from comprehensive, and is just meant to highlight a few of the different kinds of Transformer models. Broadly, they can be grouped into three categories:

This list is far from comprehensive, and is just meant to highlight a few of the different kinds of Transformer models. Broadly, they can be grouped into three categories:
- GPT-like (also called _auto-regressive_ Transformer models)
- BERT-like (also called _auto-encoding_ Transformer models)
- T5-like (also called _sequence-to-sequence_ Transformer models)
