[Course Structure] - It was great that rather than being textbook-like, it felt like you were passing on know-how for issue resolution experienced in actual work - Although I haven't developed LLM Applications yet, the course was thoroughly reviewed enough that ideas came to mind immediately after watching the lectures - Considering that you can't get everything from one course, following Byungjin's roadmap will eventually build confidence in LLM Application development through the course structure [Teaching Method] - There may be personal preferences, but the explanations really sink in and are understandable, giving you confidence that you can follow along - Even for items that could be easily overlooked, detailed examples helped understand both code and architecture at once - Most importantly, the instructor's pride in working in this field and teaching classes in this area has the effect of boosting students' confidence as well [Overall Assessment] - Using generative AI alone is insufficient, and to strengthen security against internal information being uploaded to external clouds, it's determined that LLM Applications must be developed in-house. I'm confident that completing all the courses in this roadmap will reach a certain level. ^^ - I think I will definitely take any courses that are continuously released. - It would be great if you could also provide offline sessions in addition to Online Classes. Keep fighting! ^^

실습 위주의 훌륭한 강의입니다! LangGraph, MCP, RAG 같은 복잡한 내용을 쉽게 설명해 주셔서 이해하기 쉬웠고, 실무에 바로 적용할 수 있었습니다. 강사님의 설명이 정말 명확하고 유익했어요. 추천드립니다!

Finished the course in just two days, and even got an MCP update!!! Honestly, the tuition fee is too cheap. I wish you'd raise the price so others wouldn't find out, but to help the instructor create more great lectures, there needs to be more students 😊😊 This is a core lecture that picks out only the essential points. If you want to utilize LLM 200%, make sure to take this course, and take it twice.

친절한 말씀 정말 감사합니다! 강의가 도움이 되었다니 기쁘네요. 저는 직장에서 다른 엔지니어들에게 LangGraph를 사용하고 실제 프로젝트에서 AI 에이전트를 구축하는 방법을 가르치고 있는데, 그런 실무 경험이 자연스럽게 이 강의에도 반영된 것 같습니다. 그런 실무 배경이 개념을 더 접근하기 쉽고 적용 가능하게 만드는 데 도움이 되었다니 정말 좋네요.

I received so much help from the Langchain basics to the RAG lectures, so I also took the LangGraph course. They explain the content that can be used directly in the field with high quality and in a very detailed manner. You mentioned in the lecture that you have plans to publish a book, and I would appreciate it if you could mention it in a community or something when it is published. I am interested in purchasing it.
Wow, that's a really touching review! 🥹🙏 I prepared my lecture so that it can be applied directly to practical work, so I feel very rewarded to receive such good feedback. Thank you so much for being with me from LangChain to LangGraph! I'm also working hard to prepare for the publication of the book, and I'll be sure to let you know in the community! The fact that you are interested in this gives me great strength. I will continue to repay you with helpful lectures and content. Thank you again for leaving such a sincere review!
