Getting Started with RagReader: Multi-LLM Consensus & Benchmark Tutorial
- Compare 9 concurrent RAG pipelines (Dense, Sparse, Hybrid) across GPT, Claude, and Gemini models.
- Automate ground-truth generation with Reciprocal Rank Fusion (RRF) candidate pooling.
- Evaluate retrieval and generation quality with Precision@K, Recall@K, F1@K, ROUGE-L, and LLM-based metrics.
- Stream real-time results via an interactive WebSocket-powered dashboard.
The Challenge: Why RagReader – Multi-LLM Consensus & Benchmark Was Built
Designing an AI QA system involves choosing between multiple retrieval strategies (Dense, Sparse, Hybrid) and generative models (GPT, Claude, Gemini). Without objective comparisons, developers often rely on guesswork, leading to suboptimal accuracy, latency, or cost. RagReader solves this by providing a diagnostics platform to benchmark RAG configurations side-by-side.
Core Architecture & Technical Stack Deep-Dive
Tech Stack
- Backend: Django ASGI/Channels for WebSocket streaming.
- Frontend: React Dashboard for real-time visualization.
- Database: ChromaDB for vector storage and retrieval.
- LLMs: OpenRouter integration with GPT-4o-mini, Claude 3.5 Haiku, Gemini 2.0 Flash, and Mistral Nemo.
Execution Matrix
RagReader runs 9 concurrent pipelines, combining 3 retrieval methods (Dense, Sparse, Hybrid) with 3 LLMs (GPT, Claude, Gemini). Results are streamed in real-time via WebSockets.
Key Features Breakdown & Practical Benefits
Automated Ground-Truth Generation
Uses TREC-style Reciprocal Rank Fusion (RRF) to pool candidates from multiple retrievers, eliminating manual labeling effort.
Real-Time Metrics
Calculates Precision@K, Recall@K, F1@K, and ROUGE-L scores for retrieval and generation quality.
Interactive Dashboard
Streams comparison metrics side-by-side, enabling developers to quickly identify the best-performing pipeline.
Real-World Use Cases & Applications
