Autonomous AI Agents & The ReAct Pattern

Explore multi-step autonomous agent systems using the Reason + Act (ReAct) iterative loop.

The ReAct (Reason + Act) Loop

An AI Agent differs from a chatbot because it operates autonomously in an iterative cycle:

1Thought: Reason about what needs to be done next.

2Action: Select a tool (e.g. search web, read file, run query).

3Observation: Review the tool execution output.

4Repeat: Continue until the overarching goal is completed.
