Large language models in practice, beyond the demo. Prompt engineering and its limits, RAG architectures to ground a model in your own documents, agents that can call tools, fine-tuning and criteria for choosing between proprietary and open models. You will find quantified comparisons, step-by-step LangChain and LangGraph tutorials, and production lessons on what breaks once live: cost per request, latency, hallucinations, context management and evaluation. The goal is to move from an impressive prototype to an application whose behavior you can guarantee.
