## AI overview

A comparison of open source vector databases for production AI workloads, focusing on the tradeoffs between specialized vector tools and unified platforms. It highlights Redis as a real-time, memory-first platform combining vector search, operational data, caching, session state, and application state.

## Source excerpt

Open source vector databases come in two flavors: specialized tools that handle vectors and nothing else, or unified platforms that combine vector search with operational data and caching. Many teams end up managing three systems: a vector database, a...
