Đạt TrầnThe most important concept in Module 1 is the State Schema. In Python, you can pass any variable to any function. In LangGraph, the State is strict. If you try to pass data that isn’t defined in your TypedDict, it vanishes (or causes errors depending on validation). Let’s see what happens when we try to … Read more
In a standard script, you call function A, get the result, and pass it to function B. In LangGraph, you don’t call functions directly. You place them on a “board” (the Graph) and draw lines between them. The Graph manages the execution.

Overview Retrieval-Augmented Generation (RAG) has become one of the most powerful techniques in modern AI applications. Instead of relying solely on an LLM’s training data, RAG allows models to access external knowledge by retrieving relevant information before generating responses. In this tutorial, we’ll build a minimal RAG system from scratch in about 60 lines of … Read more

My pipeline was working perfectly for weeks using docker buildx, and then suddenly—after adding a single RUN … Read more
