What is a Large Language Model?

A Large Language Model (LLM) is an advanced AI program designed to recognize and generate human-like text. Built on neural networks, particularly transformer models, LLMs analyze massive datasets to learn patterns in language.

Core Concepts

Foundation Models

LLMs belong to a broader category called foundation models (FMs), which are pre-trained on vast amounts of data and can be adapted for various tasks. Key characteristics include:

Large-scale training data
Billions of parameters
Transfer learning capabilities
Multi-task adaptability

Deep Learning Architecture

LLMs use deep neural networks with:

Multiple processing layers
Hierarchical feature learning
Complex pattern recognition
Transformer-based architecture
