Introduction to LLM Agents

What is an LLM Agent?

An LLM agent is an AI system that uses a large language model as its core reasoning engine, combined with the ability to take actions in the world.

Key Components

  1. LLM Core - The reasoning engine
  2. Memory - Context and history management
  3. Tools - External capabilities the agent can use
  4. Planning - Breaking down complex tasks

Why Agents Matter

Traditional LLMs are stateless and can only generate text. Agents extend this by:

  • Maintaining state across interactions
  • Taking real-world actions
  • Learning from feedback
  • Solving multi-step problems
