PyVectorHound
Diagnostic engine for RAG retrieval failures.
Diagnostic engine for RAG retrieval failures. Component-level analysis, root cause detection, optimization recommendations. Fix what's broken, not just metrics. - Mullassery/PyVectorHound
Hunt down retrieval problems. Fix them fast.
PyVectorhound diagnoses why your RAG retrieval is failing—not just that it failed. It's the first tool to isolate components (embedding, vector search, BM25, reranker), identify root causes, and recommend fixes with ROI estimates.
Why Star This?
Component-level diagnostics — See exactly which stage is failing (embedding, vector search, keyword search, reranker)
Fast diagnosis — 45ms root cause analysis
Root cause + recommendations — Not just metrics, actionable fixes with ROI estimates
No vendor lock-in — MIT licensed, works with 5+ open-source vector databases
Production-ready — Used in RAG/LLM systems, fully tested
What Problem Does PyVectorhound Solve?
Your RAG system's retrieval quality degraded. You know something is wrong, but not what:
Is the embedding model bad?
Is vector search returning wrong results?
Is keyword search missing matches?
Is the reranker miscalibrated?
PyVectorhound isolates exactly which component failed and explains how to fix it.
When Should You Use PyVectorhound?
Use PyVectorhound when:
Retrieval quality drops unexpectedly
You're choosing between embedding models
You want to understand retrieval performance
You need to optimize cost vs quality
You're debugging RAG system performance
