Building RAG Applications with LangChain

Description

Automatically generated AI learning skill from curated web and social media sources.

Steps

1. Learn how to build Retrieval-Augmented Generation applications. ```python
2. from langchain.chains import RetrievalQA
3. from langchain.vectorstores import FAISS
4. qa_chain = RetrievalQA.from_chain_type(llm=llm, retriever=vectorstore.as_retriever())

Code Examples

from langchain.chains import RetrievalQA
from langchain.vectorstores import FAISS
qa_chain = RetrievalQA.from_chain_type(llm=llm, retriever=vectorstore.as_retriever())

Dependencies

• Python 3.8+
• Relevant libraries (see code examples)
