The Obstacle
Architectural Friction.
Traditional RAG systems rely heavily on vector embeddings and vector databases, increasing infrastructure complexity, operational cost, and latency while reducing explainability in production AI systems.
The Synthesis
The Protocol.
Vectorless architecture using BM25 for keyword-based retrieval Structured knowledge storage using SQL databases LLM integration for contextual response generation Faster response time with reduced infrastructure overhead Explainable and deterministic response flow
Technical Blueprint.
Uses Elasticsearch/OpenSearch BM25 ranking for fast and accurate keyword-based search without vector embeddings.
Stores and retrieves information using SQL databases and structured knowledge systems for consistency and control.
Integrates OpenAI/OpenRouter APIs to generate contextual and human-like responses.
Eliminates vector database overhead to reduce infrastructure costs and improve response speed.
Deterministic retrieval provides traceable and understandable AI response generation.
