If you've taken the prerequisite course, the LangGraph course, this content is very easy to follow. In the prerequisite course, I learned well by referencing papers and implementing various architectures, but in this current course, the content is simple and focuses mainly on graphs, which felt a bit underwhelming. This current course is centered around clone projects that implement various AI services available on the market, which makes me think that the AI services out there are simpler than expected. If your goal is to study, I recommend the prerequisite course more, but if your goal is to easily and efficiently apply it directly in practice, this current course seems better! Also, while going through the course, there were quite a few parts where the instructor just read through the process of simply checking or comparing results, which felt inefficient from a learner's perspective. However, I was able to take the course by skipping those parts on my own and referencing the necessary sections well. Thank you for the great content!
