The course was very informative and showed a lot of different tools to use with Agentic AI. It was very helpful to create a RAG and vector database index from scratch.

By Vijay Kumar on 3/21/2026

some other cources for LLM and Langgraph are better.

By Ederson Rodrigues on 12/26/2025

I am in the middle of the course yet, but for now the content was fully hands-on example that help me understand better the langgraph

By David Schmitz on 5/29/2025

Il s'agit d'une approche très pragmatique de LangGraph. Le projet final est vraiment bien. Cela donne envie d'aller plus loin. J'ai toujours apprécié les cours de ce formateur.

By Grzegorz Wasilewski on 2/24/2025

not a single minute wasted and gained loads of information to use, play and experiment with. Thank you very very much. All the best!

By Zahar Veigman on 2/10/2025

Well, overall OK, personally - I don't like the idea of adding OOP to the course since it is not related to the topic. Also, I wish more details on reasoning behind implementation since basic concept of LangGraph are explained on LangChain blog.

By Emmanuel Okonkwo on 12/26/2024

I chose this course because the tutor does slow down but to explain and teach. So far so good.

By Tom Schreck on 12/26/2024

this has been a fantastic introduction to LangGraph. This is exactly what I needed to get started.

By Manjunath Mahashetti on 12/2/2024
