LLM (Large Language Model)
A large-scale neural network trained to understand and generate human language.
Detailed Definition
A Large Language Model (LLM) is a type of AI model trained on vast text corpora to understand, reason over, and generate human-readable language. Modern LLMs such as GPT-4o, Claude Sonnet 4, and Gemini 2.5 Pro are multi-modal—capable of processing not only text but also images, audio, or even video within a single conversational interface. LLMs underpin chatbots, agents, and countless AI products by providing rich language understanding and generation capabilities out of the box.
