How to wire LangGraph into a FastAPI chatbot API with streaming, persistence, and per-user threads. The production pattern that scales past demos.
Why linear LangChain chains fall over on real agents and how LangGraph's stateful graphs replace them. The state model, loops, and upgrade path.
How to use sub-graphs in LangGraph to keep complex RAG pipelines sane. The composition pattern, the state isolation rule, and when to split.
How to render a RAG pipeline as a graph with LangGraph StateGraph. The diagram, the state schema, and the debugging workflow that saves hours.
How hybrid retrieval combines vector search and graph traversal in RAG. The when, the why, and the 60-line fusion that beats either alone.
How agentic RAG uses LangGraph to plan, rewrite queries, and call tools. The graph, the state, and the nodes that turn single-pass RAG into reasoning.
How dynamic RAG re-plans retrieval mid-pipeline. The replanner prompt, the loop that recovers from bad chunks, and when this beats single-pass RAG.
Why production LangGraph agents need a postgres checkpointer and thread model. How persistence survives restarts, and the trap that loses every chat.
Learn how to build agentic workflows with LangGraph using nodes, edges, and shared state. Move from simple chains to cyclic state machines that can loop...
Learn how to build multi-hop RAG agents that can decompose complex queries into sub-questions and chain multiple retrieval steps. Understand query decom...
How assembling works in production. Learn how to wire up all the nodes in LangGraph to create a complete, self-correcting RAG agent. See it in action with
Learn how to build the decision-making nodes for an intelligent RAG agent: routing, grading, and generation. Understand how self-correction loops make a...
