All the intro code doesn't work with the latest langchain etc.
By Juan Francisco Piñera on 5/31/2024
It is completely outdated. The examples are not useful. The teacher has lots of bugs or errors during the videos, which he didn't even bother to re-record or edit. It's a shame such a low quality

I'm a full-stack developer focusing on the MERN stack and Django applications. This course is helping me integrate large language-based AI applications with my projects and boost application performance and features. Basically, I'm trying to move towards web automation, and I found this course for my first journey. I really thank the tutor, Paulo Dichone, who explains better how to use language and build an AI product.
By Heriberto Ayala on 3/24/2024
i really like the way its going so far, a lot of things are depreciated which is fine, but you keep it simple, short and to the point so i dont mean going into the docs and debugging and trying to replace the new information from the old, ive seen other tutorials that are just too in detail and they get way too confusing because they contradict themselves, you manage to be confident in your knowledge which is another reason i like the course so far, have not finished but whoever sees my review, just take your time with it and do what i did, look at the docs to debug, its only slight changes
By Bibo on 2/1/2024
He is one of the top 3 tutors on Udemy teaching Langchain ... no doubt! Take it from me cuz I bought every single course on OpenAI and Langchain here ... this definitely is one of my top choices where you'll get more than your money's worth... plus, this is the most updated one!

I absolutely like the way you walk through the code, explaining each line with details and the format. Keep creating more such content
By Chrisogonas Odhiambo on 12/31/2023
Thank you so much, Paul Dichone! Just like your other courses I have taken in Udemy, this was superbly done. I found it well explained and properly illustrated to understand. The examples served well to reinforce the knowledge. I enjoyed every bit of it and I cannot wait to extend these examples as well as try out my own ideas. I totally recommend the course to anyone considering LangChain as a framework to explore and exploit the potentials of the LLMs. Thank you!

This is the fourth LangChain course I've taken on Udemy. This was the most well-rounded of the four. The instructor does a great job in explaining what you need to know without taking you off the LangChain path. I found that many of the other courses stray way too far into web development territory or go into too much detail about the inner workings of LangChain. The real world examples are realistic tools but also remain simple in their implementations thanks to his use of Streamlit.
By Limber Martinez on 12/6/2023
Excellent course, it was very helpful for me to see the details of what I was doing in Python explained and the projects helped me understand the concepts of Langchain.
By Taiwo Megbope on 10/27/2023
Apt, to the point, extremely useful info. Also, Paulo's screen is at the perfect legibility level. Some other courses are great but you have to squint to see the instructor's screen. Excellent course Paulo.
