Large Language Model

A Large Language Model (LLM) is an artificial intelligence system trained on enormous amounts of text data to understand, generate, and manipulate human language with remarkable sophistication. These models use deep learning techniques to learn patterns in language, enabling them to perform tasks like writing, translation, summarization, and question-answering by predicting the most likely next words in a sequence. What makes these models 'large' is both the massive datasets they're trained on (often containing billions of web pages, books, and articles) and their complex neural network architecture with billions or even trillions of parameters. This scale allows them to capture nuanced language patterns, context, and even some reasoning abilities. Popular examples include GPT-4, Claude, and Gemini, which power many AI applications we use daily. LLMs work by processing text as sequences of tokens (words or word parts) and using statistical relationships learned during training to generate coherent, contextually appropriate responses. While they don't truly 'understand' language like humans do, their sophisticated pattern recognition creates the appearance of comprehension and reasoning, making them incredibly useful for a wide range of text-based tasks.
