To build effective AI agents, you need to understand the three core building blocks: Models, Tools, and Orchestration.
Large Language Models (LLMs) act as the reasoning engine. They process natural language, maintain context, and decide when to use tools. However, models alone are confined to the data they were trained on and cannot interact with the outside world.
“The reasoning capabilities of the model determine the intelligence of the agent, but intelligence without action is just passive knowledge.”
Tools give agents the ability to take action. Whether it’s querying a database, searching the web, executing code, or making API calls to a network switch, tools provide the “hands” for the AI’s “brain.”
Orchestration is the glue that holds everything together. It coordinates the loops of thought and action, handles error recovery, manages memory, and ensures the agent stays on task.
