@YosieSYX There is another intro page at https://se-education.org/guides/tutorials/aiAssistedCoding.html

Hi Prof, yep I saw that intro page. But I think the intro page that I created is different because that intro page is telling students how to use LLMs. But for mine it is to help students choose which LLM to use for different tasks. Perhaps I could add this page into the AI intro page?

@YosieSYX Best not to add too many pages with general info. The value is not worth the cost. If anything, we can augment the existing page with missing info.
