AI Glossary: RAG, Retrieval & Knowledge

RAG architecture has become fundamental to AI products, enabling grounded, up-to-date, and domain-specific responses. RAG (Retrieval-Augmented Generation) Enhancing LLM responses by retrieving relevant external information before generating output. Addresses outdated training data, hallucinations, and domain-specific knowledge gaps. More cost-effective than fine-tuning; allows real-time knowledge updates. Reference: Lewis, P., Perez, E.

AI Glossary: Training, Fine-Tuning & Data

Understanding how models are built and adapted helps designers recognize capability sources, appreciate customization options, and understand training-related behaviors and limitations. Pre-Training Concepts Pre-training The initial, computationally intensive phase of training on massive unlabeled text. During pre-training, models learn language patterns, grammar, factual knowledge, and reasoning capabilities by processing billions
