This is an excellent lecture that provides a clear understanding of the new trends and overall architecture of RAG. At first, I thought I understood everything in my head, but I felt a bit lost and empty after each section, wondering, "Wait, how do I actually do this?" However, seeing how the instructor immediately incorporated the feedback and improvement requests I provided, I felt once again that this is a great instructor and a high-quality course. I am looking forward to the rest of the course even more as practice code and additional content are being added to each section. The content is fantastic, the explanations are clear, and the instructor is very responsive to feedback, so I highly recommend taking this course!
