AI agents are intelligent software entities capable of carrying out tasks independently for a user or another system. It leverages reasoning, strategic planning, environmental awareness, and autonomous decision-making to accomplish its objectives.

Key characteristics include:

  • It operates with defined goals, either assigned by people or by other systems, and takes actions to achieve them.
  • It perceives and engages with its surroundings, whether physical or digital.
  • It makes independent choices about what actions to take, rather than relying on rigid, preprogrammed instructions.
  • In more advanced designs, it can adapt and improve its behavior over time by learning from experience.

What are AI agents?

An AI agent is a system (software or embodied) that can perceive its environment, reason about what it perceives, and take actions to achieve goals autonomously or semi-autonomously.

What’s the difference between an AI agent and a chatbot?

A chatbot is a conversational tool that responds to user messages based on a pre-designed conversation flow, while an AI agent is an autonomous system that can reason, plan, and take actions to achieve goals. In short, chatbots talk, while AI agents think and act.
