How LLMs work

Large Language Models (LLMs) are advanced AI systems that can understand and create human-like text. These models are trained on vast amounts of data to predict the next word in a sentence based on context. They use this ability to perform tasks like translation, writing, and conversation, often with impressive accuracy and nuance.

LLMs have significant real-world impact across various sectors. In healthcare, they assist in diagnosing diseases by analyzing patient data. In business, they optimize customer service through chatbots and automate content creation. For individuals, LLMs enhance personal productivity by generating emails or summarizing documents.

At their core, LLMs use deep learning techniques, specifically neural networks with many layers (hence 'large'). During training, these models learn to map input data to output predictions through millions of parameters. When used, an LLM processes a prompt, encodes its meaning, and generates a response that continues or completes the text in a coherent way.
