The article delves into the architecture of modern Large Language Models (LLMs) like GPT, explaining their shift to a decoder-only structure. This design streamlines the process by removing the encoder and cross-attention mechanisms, focusing solely on predicting the next token in a sequence. It further breaks down the components of a 'GPT block,' including self-attention with multiple heads and feed-forward networks, and touches upon the underlying matrix operations and learned weight matrices essential for token representation and context interpretation.
