Why One Search Algorithm Is Never Enough: A Taxonomy of AI Memory Retrieval
BM25, HNSW, GraphRAG, temporal decay - a practical breakdown of the search paradigms powering AI memory systems, organized by the failure mode each one solves.

We went from nomic-embed-text to OpenAI's text-embedding-3-small and thought we'd upgraded. Turns out we'd moved from bad to mediocre. Here's the full landscape of self-hosted embedding models in 2026, organized by what you can actually run on your hardware.
