    2. Corrective RAG (CRAG) Self-Grading

    The system evaluates retrieved content quality through three classifications:

    Grade Action Benefit
    Correct Proceed to generation Ensures high-quality context
    Ambiguous Expand query terms Improves precision
    Incorrect Trigger external search Prevents hallucinations

    Real-World Use Cases & Applications

    • Research Intelligence: Connecting dots across scientific papers and patents
    • Legal Discovery: Tracing citations and precedents through case law
    • Technical Documentation: Answering complex developer questions spanning multiple API references
    • Due Diligence: Automated analysis of business relationships across financial documents

    Comparison: CRAG MultiHop vs Traditional Approaches

    Feature Traditional RAG CRAG MultiHop
    Multi-step reasoning ❌ Single-step only ✅ Up to 3 hops
    Retrieval quality control ❌ No verification ✅ Self-grading
    Search methodology ❌ Single vector search ✅ Hybrid dense/sparse
    Failure recovery ❌ Complete failure ✅ Graceful degradation
    Pipeline transparency ❌ Opaque process ✅ Real-time monitoring

    Frequently Asked Questions (FAQ)

    1. How does CRAG prevent hallucinated answers?

    The system evaluates retrieved context before generation, rejecting or supplementing low-quality content. If confidence is low, it falls back to verified external sources.

    2. What makes the hybrid retrieval approach effective?

    By combining semantic vector search (dense) with keyword matching (sparse BM25), the system captures both conceptual relationships and precise term matches for comprehensive coverage.

    3. Can I customize the pipeline components?

    Yes, the UI provides toggles for each stage – you can disable multi-hop, CRAG grading, or reranking individually to suit different query types.

    4. What hardware requirements does this have?

    The system is optimized to run on standard VPS instances (4GB+ RAM) with CPU-only operation, though GPU acceleration improves reranking speed.

  • DivinityAI – Islamic Grounded RAG: Architecture & Performance Benchmark

    DivinityAI – Islamic Grounded RAG: Architecture & Performance Benchmark

    Key Takeaways:

    • DivinityAI ensures zero hallucinations in Quranic verses and Hadith citations.
    • It uses a strict corpus-lock policy grounded in authentic Quran and Hadith texts.
    • The system employs advanced techniques like HyDE expansion, hybrid search, and deterministic citation verification.
    Live Project Access: https://muslim.nevatal.id

    The Challenge: Why DivinityAI – Islamic Grounded RAG Was Built

    General-purpose large language models (LLMs) often hallucinate religious texts, fabricating Quranic surah and ayah numbers, attributing narrations to the wrong companions, and merging distinct prophetic sayings. In a domain where textual accuracy is critical, these hallucinations are unreliable and potentially misleading. DivinityAI addresses this challenge by implementing a strict corpus-lock policy, ensuring every response is grounded in authentic Quran and Hadith texts.

    Core Architecture & Technical Stack Deep-Dive

    DivinityAI is built using a modular architecture with a Django backend serving a React SPA. The system leverages ChromaDB for vector storage, BGE-M3 embeddings, BM25 sparse search, and Reciprocal Rank Fusion for hybrid search. The LLM engine uses OpenRouter (Gemini 2.5 Flash) and Groq (Llama 3.3 70B) for text generation and validation tasks.

    System Components & Interface Boundaries

    The architecture includes:

    • Frontend: React 19 single-page application styled with Tailwind CSS v4.
    • Backend: Django web service exposing REST endpoints via Django REST Framework (DRF).
    • Vector Database: ChromaDB server deployed locally on port 8040.
    • Sparse Index: rank_bm25 indexes saved on disk for fast exact-token matches.
    • Embedding Model: A local Ollama service serving embeddinggemma.
    • LLM Engine: OpenRouter handles text generation, while Groq performs high-speed validation tasks.

    Key Features Breakdown & Practical Benefits

    DivinityAI’s key features include:

    • Strict corpus-lock policy refusing answers not grounded in authentic Quran and Hadith texts.
    • Five-path Intent Router with confidence gating.
    • HyDE expansion and sub-query decomposition for nuanced queries.
    • Hybrid BM25 sparse matching combined with BGE-M3 dense embeddings.
    • Deterministic 4-tier citation verification chain.
    • Pre-generation evidence sufficiency checks and post-generation fatwa boundary / hallucination detectors.

    Real-World Use Cases & Applications

    DivinityAI is ideal for:

    • Scholarly research and authenticated Quran/Hadith reference discovery.
    • Academic study of classical Arabic religious texts.
    • Reference design pattern for high-stakes zero-hallucination domain-specific RAG architectures.

    How It Works: Step-by-Step Workflow

    The query execution pipeline includes:

    1. Intent Classification: Categorizes the query using Gemini 2.5 Flash.
    2. Scope Enforcement: Checks classification confidence and rejects off-domain queries.
    3. Expansion: Executes HyDE and splits Fiqh questions into sub-queries.
    4. Retrieval: Runs hybrid searches using BM25 and BGE-M3 embeddings.
    5. RRF & Verification: Melds retrieval lists and validates citations.
    6. Sufficiency Check: Determines if retrieved chunks contain sufficient evidence.
    7. Synthesis: Compiles the final response using Gemini 2.5 Flash.
    8. Audit: Audits the response text and appends appropriate disclaimers.

    Comparison: DivinityAI – Islamic Grounded RAG vs Traditional Approaches

    Feature DivinityAI Traditional Approaches
    Hallucination Risk Zero High
    Citation Verification Deterministic None
    Query Intent Routing Five-path Intent Router None
    Search Technique Hybrid BM25 + BGE-M3 Single Method

    Frequently Asked Questions (FAQ)

    What is DivinityAI?

    DivinityAI is a Retrieval-Augmented Generation (RAG) system built around a locked, authenticated corpus of Al-Quran and canonical Hadith compilations, ensuring zero hallucinations.

    How does DivinityAI verify citations?

    DivinityAI uses a deterministic 4-tier citation verification chain, including exact string matching, normalized matching, fuzzy Levenshtein distance, and semantic LLM fallback.
