Hi, My name is Sunny Solanki, and in this video, I provide a step-by-step guide to creating a RAG LLM App using the Python framework "llamaindex". To build our LLM app, we have used open-source LLM "llama-2" with 7B parameters. To access LLMs, we use a tool named "Ollama". The tutorial is a good starting point for someone new to LlamaIndex and who wants to learn how to create LLM Apps. It's a good introduction to the RAG concept.
