What are Large Language Models (LLMs)

GlossaryLanguage Models and Natural Language Processing

Large neural language models trained on broad data and adapted for many text and reasoning tasks.

Definition

Large Language Models (LLMs) is large neural language models trained on broad data and adapted for many text and reasoning tasks. In practical AI work, it helps teams connect a concept to data, model behavior, product choices and evaluation. The useful question is not only what the term means, but how it affects quality, cost, reliability and risk in a real workflow.

Example

A support or search system uses Large Language Models (LLMs) to process text and return answers that better match the user's request.

Why it matters

Large Language Models (LLMs) matters because large neural language models trained on broad data and adapted for many text and reasoning tasks can change how teams build, evaluate or choose AI systems.

How it works

The system represents text, analyzes structure or meaning, and evaluates whether outputs match the task and context. For Large Language Models (LLMs), the key is to connect the definition with input data, assumptions, measurable outcomes and deployment limits.

Where it is used

  • Used in search, chatbots, summarization, extraction, translation and text analytics.

Limitations

Language systems may miss context, repeat bias, hallucinate details or fail on domain-specific wording.
