Retrieval chains are famous for empowering the LLMs with retrived documents from various sources (web, pdf, documents, sql database ...).

We'll explore the chains from the python library of langchain, learn how to use the chain classes and finally show case some example.

For more information about different types of retrieval chains visit:
https://blog.langchain.dev/retrieval/

You will be acquainted with the langsmith environment to observe the steps LLMs take to deliver the final response.
