Advanced RAG with Llama 3 in Langchain | Chat with PDF using Free Embeddings, Reranker & LlamaParse

Let's build an advanced Retrieval-Augmented Generation (RAG) system with LangChain! You'll learn how to "teach" a Large Language Model (Llama 3) to read a complex PDF document and intelligently answer questions about it. We'll simplify the process by breaking the document into small pieces, converting these into vectors, and organizing them for fast answers. We'll build our RAG using only open models (Llama 3, FlagEmbedding & MS Marco reranker).
