GraphRAG: A Practitioner's Guide to 6 Advanced Architectural Patterns
Pippa and Tyler dig into a GraphRAG guide that’s really arguing for a more honest question: not “does GraphRAG work,” but “which retrieval shape matches the query shape?” They focus on the production trade-offs between strict graph querying, hybrid vector-plus-graph setups, and when knowledge graphs actually earn their keep.

Stop graphing everything: When GraphRAG actually beats vector RAG
Pippa and Tyler dig into a fresh GraphRAG piece that argues graphs only beat vector RAG when the question needs multi-hop reasoning, global sensemaking, or summary across an interconnected corpus. They walk through the mechanism, the benchmark evidence, the cost caveat, and the practical hybrid answer without pretending graphing everything is the move.

Why AI Company Brains Fail: Beyond Vector Search and GraphRAG
Pippa and Tyler unpack why a cheap vector search demo breaks on broad portfolio and exact counting questions, and why the article’s lighter entity layer may be more practical than a full GraphRAG stack.

AI Memory Beyond RAG: Vectors, Graphs, and Dense Mem
Justy and Cody dig into an article arguing that most people blur together three different things under "AI memory": startup context, retrieval, and durable state. They unpack why the author thinks plain RAG is good at finding text but bad at deciding what is current, and why graph-backed memory only helps if you add provenance, conflict checks, and explicit gates instead of letting a model quietly turn every sentence into a fact.

A RAG: Scaling Agentic Retrieval Augmented Generation via Hierarchical Retrieval Interfaces
A-RAG: Scaling Agentic Retrieval-Augmented Generation via Hierarchical Retrieval Interfaces Mingxuan Du 1 , Benfeng Xu 2† , Chiwei Zhu 1 , Shaohan Wang 1 , Pengyu Wang 1 Xiaorui Wang 2 , Zhendong Mao 1‡ 1 University of Science and Technology of China, Hefei, China 2 Metastone Technology, Beijing, China [email protected] Abstract Frontier language models have demonstrated strong reasoning and long-horizon tool-use capabilities. However, existing RAG systems fail to leverage these capabilities.

Beyond Hybrid RAG That Actually Works: Vector + BM25 + GraphRAG + Reranking in Python
This episode dives into the breakthrough of Tri-Modal Hybrid RAG, which combines BM25, Vector, and GraphRAG techniques. We explore how this innovative approach enhances search accuracy, addresses common pitfalls in retrieval, and ultimately improves user experience across various applications. The conversation highlights the significance of effective information retrieval in tech and real-world scenarios.
