Master's graduate from Beijing Institute of Technology, published four top‑journal papers, previously worked as a developer at ByteDance and Alibaba. Currently researching large models at a major state‑owned enterprise. Committed to sharing concise, practical AI large‑model development experience, believing that AI large models will become as essential as PCs in the future. Let's start experimenting now!
This article evaluates the open‑source Qwen3‑Coder‑480B‑A35B model, comparing its programming and agentic capabilities to Claude 4 and other leading models, detailing its architecture, token length, reinforcement‑learning‑after‑training technique, ecosystem tools, and real‑world code‑generation case studies.
The article analyzes OpenAI's ChatGPT Agent—its launch, performance metrics, all‑in‑one tool integration, real‑world use cases, pricing tiers, core capabilities, and how it surpasses competing agents like Manus, highlighting its significance for the next generation of AI agents.
This tutorial walks through LangChain's core concept of Chains, demonstrating how to build simple, composite, and custom node chains, use prompt templates and structured output parsers, and leverage the LCEL syntax for clean, modular LLM applications.
This tutorial explains LangChain's core modules and three‑layer architecture, shows how to set up a Python environment, and provides concrete code examples for connecting SiliconFlow Qwen3‑8B and DeepSeek models via the init_chat_model API, including result inspection and references to official documentation.
This article introduces AI Agents and explains why LangChain is the leading framework, detailing its core concepts, three‑layer architecture, key features, comparison with other agent frameworks, and showcasing popular projects built with LangChain and LangGraph.
The article reviews Grok 4’s flashy launch and claimed first‑principles advantage, then presents benchmark results—showing strong reasoning, multimodal and agent scores but disappointing coding performance versus DeepSeek‑R1—concluding that the model’s real‑world capabilities fall short of its hype.
This article demonstrates how to construct a knowledge graph from a 58,099‑character document using GraphRAG, measures the indexing time on an M2 PRO machine, and compares Global, Local, and Drift query modes, highlighting three scenarios where Local mode is unsuitable.
This article walks through the complete GraphRAG workflow—from environment setup and indexing to command‑line and Python API queries—demonstrating how to build a knowledge graph, tune prompts, and retrieve high‑quality answers using Microsoft’s GraphRAG implementation.
This article walks through GraphRAG’s retrieval phase, showing how knowledge‑graph entities, relationships, and community reports are assembled into a query context, comparing local and global modes with traditional RAG, and illustrating the process with a concrete “Age of Big Data” example.
This article walks through the complete GraphRAG knowledge‑graph building pipeline—text splitting, entity extraction, relation mining, community clustering, and report generation—using a concrete example from the book “The Age of Big Data,” and explains why each step improves retrieval and answer quality.
