Can GPT like decoder only models be used for classifcation

Hi I am wondering if one can use GPT like decoder only models for classification? I understand that these models are most suited for things auto-complete the sentences predicting the most probable next word, due to the representation computed for a given token in this architecture depending only on the left context. Hower, can/should such a model be used for classification, since it is technically possible? Are there any use cases for it or is it not actually a model …
