Very helpful. I especially appreciated seeing the details and use cases you showed and explained. I am new to these concepts, so having you explain the basics is invaluable. For example, one of my favorite sections was understanding the concept of how LLMs combine “reasoning” and “knowledge.” And, having you then walk through the actual examples is what makes this video one of the best I have watched. Thanks so much!

@trickstergaming3963 1 year ago

grt video sir , really interesting , already got an idea in which im going to use it , and also out of context but when you said in the last - "notified" , it sounded like "naughtified" haha that made my day so funny

@illiteratenerd 2 years ago

I've been watching tutorials from past 10 months and This is the best tutorial to understand some of the foundation concepts of how langchain works.

@leenanaik5397 1 year ago

I followed this video end end and gained a good understanding. I truly appreciate your hard work, and detailed explanations. Many folks just zoom fast, but I could follow along. Wherever APIs have changed, I just googled, chatgpted, and fixed and moved ahead.

True thanks.

I will follow your entire series.
