This article explains the fundamentals of Large Language Models (LLMs), defining them as models trained to process sequences of tokens and generate responses. It details the training process, including pre-training and fine-tuning, and highlights that LLMs can answer questions, summarize, translate, and generate code based on learned patterns. However, LLMs cannot independently search the internet, edit files, or provide real-time data post-training. The piece differentiates LLMs from AI agents, explaining that agents combine LLMs with workflows and tools to perform tasks and maintain conversational context, unlike LLMs which solely process given input.
