Build Agents from Scratch (Building Advanced RAG, Part 3)

In this third video of this series we teach you how to build LLM-powered agentic pipelines - specifically we teach you how to build a ReAct agent (Yao et al.) from scratch!

We do this in two parts:
1. First define a single execution step using LlamaIndex query pipelines to define an agentic DAG. We use special components to maintain mutable state; this state can be carried over to the next step of execution.

2. We can then wrap this DAG in an agent worker that can execute this DAG step-by-step or e2e until complete.
