Large language models, despite their impressive capabilities, are not inherently magical. The Transformer architecture, while foundational, is only one part of the equation. The true transformation from a basic word predictor to a functional chatbot involves three distinct training phases. The initial phase, pretraining, involves predicting the next word in a sequence across vast datasets, which surprisingly imbues the model with a broad understanding of the world. However, this raw engine lacks the ability to be helpful or directly answer user queries, necessitating further specialized training rounds to align its behavior with user intent. AI
