LLM agent
An AI agent where a large language model (LLM) is the cognitive center: the brain that reasons, plans and makes decisions to 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.
