Frequently Asked Questions

- What is RAG and why does it matter for my application?

RAG (Retrieval Augmented Generation) connects large language models to your own data sources — documents, databases, knowledge bases — so AI responses are grounded in accurate, company-specific information rather than general knowledge.

- What types of RAG systems does NerdHeadz build?

NerdHeadz builds document Q&A systems, customer support knowledge bases, internal search tools, content generation engines, and AI assistants that reference proprietary data with high accuracy.

- How does NerdHeadz ensure RAG accuracy?

NerdHeadz implements chunking strategies, embedding optimization, re-ranking models, and evaluation frameworks to minimize hallucination and ensure the AI retrieves and generates accurate answers from your data.

- What data sources can RAG systems connect to?

RAG systems can connect to PDFs, Word documents, databases, APIs, CRMs, help centers, wikis, Notion, Google Drive, Confluence, and most other structured or unstructured data sources.

- How long does it take to build a RAG system?

A basic RAG implementation takes 4–8 weeks. More complex systems with multiple data sources, fine-tuned retrieval, and production-grade evaluation typically take 8–16 weeks.
