In Module 4.1 you learned how RAG gives an LLM access to your documents. This module covers the next step: what happens when an LLM does not just answer a question but takes actions — browsing the web, writing and running code, calling APIs, filling forms, and coordinating with other AI systems. That is what AI agents do.

The previous three modules covered how enterprise AI works under the hood — RAG, agents, fine-tuning. This final Unit 4 module is the most immediately practical: tools you can use today, without writing a single line of code, to build AI-powered workflows that automate real tasks.
