What is an AI agent

An AI agent is an autonomous software system that uses AI to complete specific tasks or work toward a defined goal. AI agents are typically narrower in scope than agentic AI, which describes the broader ability to coordinate multiple agents, systems, and actions toward an outcome. Think of agents as the individual workers within a larger agentic AI system.

How do AI agents work?

AI agents gather information from their environment, such as applications, systems, and data sources, use AI models to understand that information, and decide what action to take toward a defined goal. They can connect with external systems and tools to carry out those actions. Multiple agents can also work together, with each handling a specific task as part of a larger workflow.

Why are AI agents important?

AI agents can perform work with less constant human oversight, allowing employees to focus on higher-value activities. They can independently handle defined tasks and business processes while serving as building blocks for more advanced agentic AI systems.

Benefits and use cases

Common uses include handling customer support requests, monitoring systems, triggering alerts or remediation steps, managing scheduling and routine administrative work, and completing steps within larger workflows. For example, an agent might retrieve information, update a record, route an approval, or work across systems to trigger the next step in a business process.
