Technical Note: Understanding the Token Cost of Persistent AI Memory

Persistent memory trades an upfront ingestion cost for cheaper queries. We measure where the tokens go in cognee, model the trade-off, and find break-even at roughly 23–26 repeated queries — after which the gap keeps widening.

AI Knowledge Base: Building a Retrieval-Ready Knowledge Layer

An AI knowledge base needs more than stored documents. Source context, entity relationships, and plural retrieval strategies are what turn stored data into reliable, agent-ready knowledge.

What Is a Knowledge Base? (and Why Most of Them Stop Working)

A knowledge base is a centralized system for storing reusable information — but most fail because of ownership gaps, drift, and no clear sense of what actually belongs in them.
