What are AI agents?

This video introduces AI agents beyond basic chatbots, explaining how they can reason, decide, and take autonomous action. Smitha covers the ReAct framework and three core agent patterns before demonstrating how to build a self-correcting Blog Writing Agent using Google ADK. The tutorial shows developers how to combine Planner and Writer agents with validation and loop mechanisms to create AI systems that catch their own mistakes and retry automatically. Perfect for developers looking to build autonomous multi-agent systems in Python.
