An AI agent is a model that is capable of reasoning, planning, and most importantly, interacting with its environment using tools that it has been provisioned to access. These capabilities allow agents to take meaningful actions, not simply generate text responses.

Why are AI agents important?

Agents enable large language models (LLMs) to move beyond simple text generation into autonomous, goal-driven workflows.  They can take initiative, call tools, and coordinate multi-step tasks—making them essential for building scalable, intelligent systems that can operate in real-world environments.
