Why Agent Memory Goes Beyond Vector Databases: Inside MNEMOVELA’s Cognition Runtime Model

The article explains that typical agent systems store long‑term memory as raw chat logs embedded in a vector database, which only captures similarity, and introduces MNEMOVELA’s cognition runtime model that classifies memories into types, uses Git‑like branching, hybrid retrieval, and context assembly to provide semantically rich, versioned agent memory.
