LLM Agent
Quick definition
An AI agent where a large language model (LLM) serves as the cognitive center — the brain that reasons, plans and makes decisions to autonomously execute tasks.
Detailed explanation

An LLM agent is an AI system where a large language model like GPT-4o, Claude or Gemini forms the central reasoning module. The LLM processes the context, chooses the next action, and generates instructions for tool use. LLM agents are the dominant architecture for modern autonomous AI agents.
Synonyms
Examples
An LLM agent for B2B sales uses GPT-4o to identify relevant prospects, write personalized emails and generate CRM updates.
When to use this?
Use 'LLM agent' in technical contexts to emphasize that the AI system uses a large language model as its reasoning module.
