Any 101 Educational Resources That Explore Technical Aspects of AI?

Does anyone have any good recommendations for courses or free online videos on the subject?

Almost every AI 101 course covers topics like what AI can do and how it can be useful, which is all fine, but I’m seeking to begin learning more of the technical aspects of how it works and how AI models are built. The problem I run into is that there don’t seem to be many beginner friendly courses or videos that ELI5 from the ground up on the subject. It’s either super technical advanced talk or benign basic info like “this is what AI can do”.
