An AI agent is software that observes its environment, decides what to do, and takes action to achieve a goal. In practice, it ingests inputs like user requests, logs, or system events, then applies reasoning with models such as large language models to select and execute the next best step without step by step human instructions. Agents can be simple rule followers or adaptive systems that learn from outcomes and refine behavior over time.

AI agents operate in an observe–decide–act loop that runs continuously.
The result is a virtual teammate that can answer, execute, and follow through, escalating to people only when the task is high risk, unusual, or ambiguous.
Agents move software from passive to proactive. They notice events and act immediately, they hide enterprise complexity behind plain language, and they handle many tasks at once without fatigue. Instead of clicking through forms or remembering which system owns which function, people state the outcome they want. The agent navigates the stack and returns a result. That reduces delays between detection and response, compresses repetitive steps, and grounds actions in data. In service contexts, agents provide instant, round the clock help that improves service levels while shrinking manual workload.
