Follow a sequenced roadmap instead of piecing together disconnected tutorials.
A structured, progressive roadmap for developers seeking to master AI agents, covering Python foundations, LangChain, LangGraph, and private multi-agent RAG.
A comprehensive curriculum taking you from zero programming knowledge to professional data manipulation, mathematical visualization, and core ML model building.
Latest from the library
Start with recent code-first guides, or filter the library by the skill you are building.
Build Adaptive RAG in LangGraph that routes each query to a vector store, a SQL employee database, or live web search — with SQLite short-term memory.
Build a ReAct agent in LangGraph that wraps retrieval as a tool, decides when to call it, decomposes comparison questions, and answers SEC filings with citations.
Build a self-correcting CRAG workflow in LangGraph that grades retrieved documents, rewrites weak queries, and falls back to web search before answering.
