I discuss why and how to build from scratch a RAG/LLM system for enterprise, without GPU or deep neural networks. Topics include accuracy, security, speed, scalability, no hallucination, exhaustivity in the prompt results, model evaluation issues, as well as real-time fine-tuning with intuitive parameters, self-tuning, efficient crawling to retrieve and leverage the underlying contextual elements, hierarchical chunking, token types, un-stemming, problems and workarounds when using Python libraries. The case study features the Nvidia corpus of public financial reports available as PDFs. Finally, I show how to design a great UI far more useful than a prompt box, an efficient backend database architecture, how to deal with various corpuses (Web, database, PDFs), multimodality, back-end agents that the user can select from the UI, sub-LLMs, and how to design your LLM to minimize prompt engineering.
