Historical Development

The evolution of Large Language Models (LLMs) has been marked by significant architectural innovations since their inception. From 2018 onwards, the field witnessed a paradigm shift with the emergence of foundation models that could generalize to unseen tasks through scaling. This trajectory has been characterized by the transition from simple neural language models to sophisticated transformer architectures with advanced attention mechanisms.
