Retrieval-Augmented Generation - RAG
EEnhance your AI with accurate, up-to-date information from your own (private/company) knowledge base using state-of-the-art RAG architecture. Our solutions leverage vector embeddings, semantic search, and large language models to deliver precise, context-aware responses. We support multi-hop retrieval and streaming RAG for faster, more comprehensive answers across complex documents. Easily integrate with popular vector databases like Weaviate, Qdrant, pgvector and FAISS—optimized for scale, security, and real-time updates.
What is Retrieval-Augmented Generation?
Retrieval-Augmented Generation (RAG) is an advanced AI framework that enhances large language models (LLMs) by integrating them with external knowledge retrieval systems. While LLMs excel at generating responses based on general knowledge, RAG extends their capabilities by dynamically accessing and incorporating up-to-date information from external sources. RAG had its peak in 2023 and 2024 but it remains relevant as a cornerstone of a LLM-solution.
Core Components:
- Retriever: Efficiently searches and retrieves relevant information from knowledge bases using vector similarity search
- Generator: Processes the retrieved context to generate accurate, well-grounded responses
- Vector Database: Stores document embeddings for fast semantic search and retrieval
Technical Advantages:
- Reduced hallucination through evidence-based generation
- Improved accuracy with source attribution
- Dynamic knowledge updates without model retraining
- Efficient handling of domain-specific knowledge
How RAG Works
Our RAG implementation follows a sophisticated, multi-stage pipeline designed for maximum accuracy and performance
Document Processing
- Text Extraction: PDFs, DOCs, HTML, and more
- Semantic Chunking: Context-aware text segmentation
- Embedding: Transformers (e.g., BERT, RoBERTa, MPNet)
- Storage: Vector databases (Pinecone, Weaviate, FAISS)
Query Processing
- Query Expansion: Generate multiple query variations
- Hybrid Search: Combine BM25 + Dense Retrieval
- Re-ranking: Cross-encoders for precision
- Context Assembly: Dynamic context window management
Generation & Enhancement
