Introduction: Agentic Systems

From Answering to Acting

This module explains systems that use models to choose actions.

Earlier modules focused mainly on generating answers. Here, the system can also take actions through tools.

For example, an agent reads a ticket, looks up an order, and proposes a refund. The application checks policy and permissions before issuing it.

This is Family 3 from Module 1, and it inherits everything you built to get here.

Agents generate text, so Module 4's economics apply at every step
