RAG System Development

Unihox builds enterprise Retrieval-Augmented Generation (RAG) systems that combine the power of LLMs with your organization's knowledge. Create intelligent Q&A systems, document search, and knowledge bases that deliver accurate, sourced answers.

What is RAG (Retrieval-Augmented Generation)?

RAG (Retrieval-Augmented Generation) is an AI architecture that enhances Large Language Models by giving them access to external knowledge sources. Instead of relying solely on training data, RAG systems retrieve relevant documents from your knowledge base and use them to generate accurate, contextual, and up-to-date responses.

This approach solves key LLM limitations: hallucinations (making up facts), outdated information (knowledge cutoff), and lack of domain expertise. RAG enables your AI to answer questions about your specific documents, products, policies, and internal knowledge.

Frequently Asked Questions

What is RAG (Retrieval-Augmented Generation)?

RAG (Retrieval-Augmented Generation) is an AI architecture that enhances LLM responses by retrieving relevant information from external knowledge sources before generating answers. Instead of relying solely on the model's training data, RAG systems search through your documents, databases, or knowledge bases to find relevant context, then use this information to generate accurate, up-to-date, and grounded responses.

When should I use RAG vs fine-tuning an LLM?

Use RAG when: (1) Your data changes frequently, (2) You need to cite sources, (3) You have large document collections, (4) You need real-time information. Use fine-tuning when: (1) You need the model to learn a specific style or tone, (2) You have stable, unchanging domain knowledge, (3) You need faster inference without retrieval latency. Many enterprise solutions combine both approaches.

What vector databases does Unihox work with?

Unihox has expertise in all major vector databases: Pinecone (managed, scalable), Weaviate (open-source, feature-rich), ChromaDB (lightweight, local), Qdrant (open-source, performant), Milvus (enterprise-grade), PostgreSQL with pgvector (SQL-compatible), and Elasticsearch with vector search. We help you choose based on scale, cost, and requirements.

How much does RAG system development cost?

RAG development costs depend on complexity and scale. Basic RAG implementations for document Q&A start at $10,000-25,000. Enterprise RAG systems with multiple data sources, hybrid search, and advanced features range from $30,000-100,000. Large-scale production systems with millions of documents can cost $100,000+. Contact us for a detailed estimate.

How do you reduce hallucinations in RAG systems?

We implement multiple strategies: (1) High-quality document chunking and embedding, (2) Hybrid search combining semantic and keyword search, (3) Reranking retrieved documents for relevance, (4) Prompt engineering to ground responses in retrieved context, (5) Confidence scoring and source attribution, (6) Guardrails to detect and prevent fabricated responses.

Can RAG systems work with private/confidential data?

Yes, Unihox builds secure RAG systems for sensitive data. Options include: (1) On-premise deployment with local LLMs (Llama, Mistral), (2) Private cloud with VPC isolation, (3) Encrypted vector storage, (4) Role-based access control for documents, (5) Audit logging for compliance. We help enterprises meet GDPR, HIPAA, and SOC 2 requirements.
