Your question is very broad. Being a PhD student, I can only say that fine-tuning happens all the time. Research in particular areas require fine-tuning pre-trained models on specific tasks, taking advantage of the amount of data seen during pre-training. It's unlikely that your thesis will be solely about fine-tuning. However, chances are you will fine-tune many models during your thesis, for various tasks depending on your field of research.

thanks for your reply. and sorry for my bad question. i like ai/ml, but is very huge. and i'm not a master in math... but i want to research in this field and i don't know in which domain. or how can i start, i don't have mentors and my uni is not very good, can i ask some question to you?
