What is Large Language Model (LLM)?
A large language model is an AI system trained on vast amounts of text to understand and generate human-like language. LLMs like GPT and Claude power chatbots, copilots and content generation by predicting the most likely next token in a sequence.
LLMs are the engines behind modern generative AI. They're trained on broad corpora, then adapted to specific tasks through prompting, fine-tuning or retrieval. In enterprise software they underpin assistants, document processing, summarisation and code generation.
