What is a Large Language Model (LLM)?

Updated May 16, 2026

Short answer

An LLM is a neural network trained on large text corpora to understand and generate human-like language.

Deep explanation

Large Language Models are transformer-based architectures trained on massive datasets using self-supervised learning. They learn statistical relationships between tokens and generate outputs by predicting the next token in a sequence. Their capabilities include summarization, reasoning, translation, and code generation, though they do not 'understand' language in a human sense.

Real-world example

Chatbots like customer support assistants use LLMs to answer user queries automatically.

Common mistakes

  • Assuming LLMs have true understanding or consciousness.
