Focused on deep research and development of large-model applications. Authors of "RAG Application Development and Optimization Based on Large Models" and "MCP Principles Unveiled and Development Guide". Primarily B2B, with B2C as a supplement.
This article walks through the theory behind ReAct agents and demonstrates how to design, implement, and test a ReAct‑style AI agent using LlamaIndex Workflows, complete with Python code, custom events, tool integration, and a full reasoning‑action‑observation loop.
This guide introduces LangGraph Studio, a visual IDE for creating, testing, and debugging multi‑step AI agents built with LangGraph, walks through building a simple agent, explains required Docker setup, project configuration files, and demonstrates how to load, run, and troubleshoot agents using the studio’s interactive features.
This article compares GraphRAG with traditional RAG across seven dimensions—suitable scenarios, knowledge representation, retrieval, comprehensive queries, hidden‑relationship understanding, scalability, and performance‑cost trade‑offs—explains how they can be fused, and offers guidance on selecting the right approach for complex data‑driven applications.
This article presents eight practical optimization recommendations for the indexing stage of enterprise‑level Retrieval‑Augmented Generation (RAG) applications, covering chunk creation, abbreviation handling, multimodal document processing, semantic enrichment, metadata usage, alternative index types, and embedding model selection.
This article explains how to construct a multi‑agent AI research assistant using LangGraph and the open‑source GPT‑Researcher project, detailing the system architecture, agent roles, state design, workflow creation, parallel sub‑processes, and code examples for autonomous online research and report generation.
This guide explains how to query a Microsoft GraphRAG knowledge graph using the official CLI, API, and a custom Neo4j implementation, covering both local and global retrieval modes, vector index creation, Cypher query customization, and integration with LangChain for end‑to‑end RAG pipelines.
This article explains the fundamentals of Microsoft GraphRAG, details its indexing pipeline—including text chunking, entity‑relationship extraction, community detection, and description generation—shows how to set up the graphrag library, create adaptive prompts, build the index, and import the resulting graph into Neo4j for visualization and analysis.
This guide explains how to enhance large language model outputs by constructing a GraphRAG pipeline that transforms relational data into a Neo4j knowledge graph, creates nodes and relationships via Python, and leverages LangChain's GraphCypherQAChain for accurate, context‑aware retrieval and generation.
This article explains how to handle complex multimodal PDFs in RAG systems, outlines extraction, indexing, and multimodal model integration, details four query‑rewriting strategies (HyDE, stepwise, sub‑question, backward), and presents key evaluation metrics and tools for assessing RAG performance.
This article walks through creating a LangGraph‑based multi‑agent application that automatically generates a movie scene, selects characters, simulates dialogue, and writes the script to a Word document using local Ollama‑powered LLMs and a custom workflow.
