LangChain

This is a playlist rather than a single course: 17 videos, about 11 hours 40 minutes in total, from Krish Naik. Because it is a long run of separate videos, it works as a reference set you can dip into by topic.

Who it suits

Learners who prefer working through a sequence of videos at their own pace, and who want LangChain covered at length rather than in one session.

Before you start

The listing gives only the count and running time, so check the video titles to see which parts of LangChain each one covers before you commit to the full set.
