Should you pick fine tuning vs RAG, RAG vs fine tuning, when you want to train LLM on your data and ship custom AI with your data? In this video, I break down what is really happening under the hood, from LLM fine tuning with LLM weights, a loss function, a training loop, and supervised fine tuning, to retrieval augmented generation with prompt engineering, context injection, a vector database, embeddings, similarity search, semantic search, and vector search inside a practical RAG pipeline.

You will see real client outcomes for LLM customization, including fine tuning limitations, RAG limitations, troubleshooting RAG, and RAG best practices for a knowledge base chatbot, document retrieval, grounding LLM, and how to reduce hallucinations when you build custom chatbot systems, from a simple enterprise chatbot to more advanced setups.
