Reranking and the Recall You Throw Away
You added a reranker because retrieval quality was not good enough. The relevant passage kept landing at rank eight when it should have been…
Chunking Is Where RAG Silently Fails
You have tuned everything. A better embedding model, a reranker, hybrid search. Retrieval quality is still not what it should be, and you cannot…
Research Vault: Open Source Agentic AI Research Assistant
The Problem Nobody Talks About I was drowning in research papers. Not metaphorically—I had 50+ PDFs, dozens of articles, and a note-taking system that…
Embedding Drift: Why Changing Your Model Re-Indexes Everything
You upgrade your embedding model. The new one benchmarks better, so you point your pipeline at it, ship it, and within a day retrieval…
The Hidden Architecture Behind Dense Vector Search (and Why It’s Hard to Scale)
Most people think dense vector search works like this: embed your documents store the vectors run cosine similarity Done. This is the biggest misunderstanding…
The Hidden Complexity Behind Scaling Dense Vector Search
A systems-level explanation for engineers, architects, and anyone building RAG, search, or agent infrastructure. Dense retrieval looks clean on paper. You take an embedding…
