AI agents (also known as artificial intelligence agents) are programs or systems that receive information from the external environment and perform some action in response. Moreover, they do this autonomously — human involvement is not required.

A chatbot operates based on artificial intelligence and responds to user requests, solving specific tasks and gradually learning. It is activated only by human initiative, so it cannot be considered fully autonomous. Because of this, there are different opinions on whether a chatbot should be considered an agent or not.

LLM-based agents are a new class of intelligent agents that use large language models (LLMs) as a central controller. Unlike standalone LLMs, agents have enhanced capabilities:

1. Perceiving external data and using tools
2. Solving complex tasks through collaboration between multiple agents
3. Interacting with humans
