Cognee Open-Source Framework Unifies Vector, Graph, and Relational Memory for AI Agents
Developer Akshay Pachaar argues AI agent memory requires three data stores—vector, graph, and relational—to handle semantics, relationships, and provenance. His open-source project Cognee unifies them behind a simple API.
Beyond Vector Search: How Core-Based GraphRAG Unlocks Deeper Customer Intelligence for Luxury Brands
A new GraphRAG method using k-core decomposition creates deterministic, hierarchical knowledge graphs from customer data. This enables superior 'global sensemaking'—connecting disparate insights across reviews, transcripts, and CRM notes to build a unified, actionable view of the client and market.
We Cut Embedding Storage Costs by ~90% — Replacing S3 with PostgreSQL
A team cut embedding storage costs by ~90% by migrating from S3 to PostgreSQL with pgvector, enabling efficient vector search and on-demand retrieval for RAG and recommender systems, with no performance loss.
The Semantic Void: A RAG Detective Story
A first-person technical blog chronicles rebuilding a vector store index on GCP, exposing a 'semantic void' where embeddings fail to capture meaning. This serves as a cautionary tale for any RAG implementation, including retail chatbots and product search.
FalkorDB: Graph Database for Multi-Hop AI Queries in Milliseconds
FalkorDB, an open-source graph database, stores connections as a sparse matrix to accelerate multi-hop queries by 100x. Combined with built-in vector search, it enables GraphRAG systems that answer complex relational questions without pre-built articles.
Building a Semantic Recommendation System from Scratch
An engineer documents the process of building a semantic recommender using embeddings and vector search, focusing on the practical challenges and failures encountered. This is a crucial reality check for teams moving beyond collaborative filtering.
IBM Demonstrates Extreme Scale for Content-Aware Storage with 100-Billion
IBM Research announced a breakthrough in vector database technology, achieving storage capacity of 100 billion vectors. This enables content-aware storage systems that can understand and retrieve data based on semantic meaning rather than just metadata.
