    Live Project Access: https://crag.nevatal.id

    The Challenge: Why CRAG MultiHop Reasoning Engine Was Built

    Standard Retrieval-Augmented Generation (RAG) pipelines often struggle with multi-hop questions and ambiguous or weak contexts. Complex questions requiring logical connections across multiple documents cannot be answered with a single search step. Additionally, retrievers frequently return noisy or irrelevant chunks, leading to incorrect or hallucinated outputs. The CRAG MultiHop Reasoning Engine was developed to address these challenges by orchestrating a composite pipeline that decomposes complex questions, evaluates retrieved contexts, and refines searches dynamically.

    Core Architecture & Technical Stack Deep-Dive

    System Components & Deployment Topology

    The CRAG MultiHop Reasoning Engine is deployed as a containerized multi-service stack using Docker Compose. The frontend is a React application built via Vite, served statically inside Nginx. The backend runs on Django ASGI using Daphne to handle HTTP and WebSocket connections. Asynchronous task processing is managed by Celery with Redis as the broker. ChromaDB serves as the vector database, while PostgreSQL handles relational data storage.

    Models Pipeline

    The system employs a combination of local CPU inference and cloud APIs for various tasks:

    • Embeddings: Generated using google/gemini-embedding-2-preview via OpenRouter.
    • Reranker: Local PyTorch model jinaai/jina-reranker-v3.
    • CRAG Evaluator: Local PyTorch model intfloat/multilingual-e5-small.
    • Generator LLM: Cloud-based qwen/qwen3-30b-a3b-instruct-2507 via OpenRouter.

    Key Features Breakdown & Practical Benefits

    Sequential Multi-Hop Query Decomposition

    The engine detects when a query requires multiple hops, splitting it into logical sub-queries and merging results from previous hops into subsequent searches.

    Corrective RAG (CRAG) Self-Grading Evaluator

    Retrieved contexts are graded as correct, ambiguous, or incorrect. Ambiguous contexts are refined, while incorrect contexts trigger external fallback searches.

    Hybrid Retrieval & Local Reranking

    The system merges dense vector search with BM25 sparse retrieval, reranking results using a local Cross-Encoder model to ensure relevance.

    Real-Time WebSocket Event Streaming

    Users receive live updates on pipeline progress, including retrieval, grading, reranking, and generation stages.

    Real-World Use Cases & Applications

    The CRAG MultiHop Reasoning Engine is ideal for complex research and multi-document intelligence investigations requiring multi-step deductions. It also serves as a developer reference implementation for self-grading agentic RAG workflows.

    How It Works: Step-by-Step Workflow

    When a user submits a query, the engine follows a sequential workflow:

    1. Query Decomposition: Breaks down the query into sub-queries.
    2. Hybrid Retrieval: Combines dense and sparse retrieval methods.
    3. CRAG Evaluation: Grades and refines retrieved contexts.
    4. Merge & Rerank: Deduplicates and reranks results.
    5. Answer Generation: Synthesizes the final response.

    Comparison: CRAG MultiHop Reasoning Engine vs Traditional Approaches

    Feature CRAG MultiHop Reasoning Engine Traditional RAG
    Multi-Hop Query Handling Yes No
    Self-Grading Retrieval Yes No
    Hybrid Retrieval Yes No
    Real-Time Progress Tracking Yes No

    Frequently Asked Questions (FAQ)

    What is the CRAG MultiHop Reasoning Engine?

    The CRAG MultiHop Reasoning Engine is a Corrective Retrieval-Augmented Generation system designed to handle complex multi-hop queries with self-grading retrieval and local reranking.

    How does the engine handle ambiguous contexts?

    Ambiguous contexts are refined and decomposed into atomic terms, while incorrect contexts trigger an external fallback search.

    What models are used in the pipeline?

    The pipeline uses google/gemini-embedding-2-preview for embeddings, jinaai/jina-reranker-v3 for reranking, intfloat/multilingual-e5-small for CRAG evaluation, and qwen/qwen3-30b-a3b-instruct-2507 for answer generation.

    Can I configure the pipeline stages?

    Yes, users can toggle pipeline stages such as Multi-Hop, CRAG, Reranking, and retrieval methods on a per-query basis via the UI.

    Conclusion & Next Steps

    The CRAG MultiHop Reasoning Engine represents a significant advancement in Retrieval-Augmented Generation technology, offering robust solutions for complex query handling and context refinement. Explore the live project at https://crag.nevatal.id to experience its capabilities firsthand.

  • DivinityAI – Islamic Grounded RAG: Architecture & Performance Benchmark

    DivinityAI – Islamic Grounded RAG: Architecture & Performance Benchmark

    Key Takeaways:

    • DivinityAI enforces a strict corpus-lock policy to prevent hallucinations in Quran and Hadith searches.
    • It uses a hybrid retrieval system combining BM25 sparse search and BGE-M3 dense embeddings for accurate results.
    • The system includes deterministic citation verification and post-generation hallucination checks.
    Live Project Access: https://muslim.nevatal.id

    The Challenge: Why DivinityAI – Islamic Grounded RAG Was Built

    General-purpose large language models (LLMs) frequently hallucinate religious texts, fabricating Quranic verses and Hadith narrations. In a domain where textual accuracy is critical, these hallucinations can be misleading and harmful. DivinityAI was built to address this challenge by providing a Retrieval-Augmented Generation (RAG) system that is strictly grounded in authenticated Quran and Hadith sources.

    Core Architecture & Technical Stack Deep-Dive

    System Components & Interface Boundaries

    DivinityAI is built as a modular application with a Django backend serving a React SPA, deploying local embeddings and remote LLM orchestrators:

    Query Execution Pipeline

    A query execution runs through a series of sequential services:

    1. Intent Classification: Classifies queries into Quran, Hadith, Fiqh, Calculation, or Off-Domain.
    2. Scope Enforcement: Rejects off-domain queries or those with low confidence.
    3. Expansion: Uses HyDE and sub-query decomposition for complex queries.
    4. Retrieval: Combines BM25 sparse search and BGE-M3 dense embeddings.
    5. RRF & Verification: Blends results via Reciprocal Rank Fusion and verifies citations.
    6. Sufficiency Check: Ensures retrieved chunks contain sufficient evidence.
    7. Synthesis: Generates the final response using Gemini 2.5 Flash.
    8. Audit: Runs post-generation hallucination and boundary checks.

    Key Features Breakdown & Practical Benefits

    Strict Corpus-Lock Policy

    DivinityAI refuses to answer queries that cannot be grounded in authenticated Quran and Hadith sources, ensuring zero hallucinations.

    Hybrid Retrieval System

    The system combines BM25 sparse search for exact keyword matches and BGE-M3 dense embeddings for semantic understanding, providing comprehensive and accurate results.

    Deterministic Citation Verification

    Citations are verified through a 4-tier chain: exact match, normalized match, Levenshtein distance, and semantic check.

    Real-World Use Cases & Applications

    • Scholarly research and authenticated Quran/Hadith reference discovery without hallucination risks.
    • Academic study of classical Arabic religious texts and cross-source comparative analysis.
    • Reference design pattern for high-stakes zero-hallucination domain-specific RAG architectures.

    How It Works: Step-by-Step Workflow

    The workflow begins with user query classification and proceeds through retrieval, verification, and generation, ensuring grounded and accurate responses.
