I’m a freshmen in TJU, and the title is my innovation and entrepreneurship event. Can you tell me the general and quickest way to learn the relevant knowledge? The intention is to integrate the large model into our university’s online judge website for teaching.

I know a little about it. I think here are two available ways: Large model fine-tuning (Actually I only know the name) or make our own dataset to train a open source model.
So I want to hear some suggestions about which way is easier or a feasible way to do it.(Such as..where can I find some dataset about c++ codes or algorithms? ). If i asked some amusing questions, please tell me the impossible part.
Sorry for my poor English.
