Overview

What is RAG Development & Evaluation?

Retrieval-Augmented Generation (RAG) is the most practical way to put LLMs to work on your own data. But most RAG implementations fail in production — poor retrieval accuracy, runaway costs, hallucinated answers and no way to measure what’s working.

We build production RAG systems that deliver accurate, grounded answers at scale. Our approach includes systematic evaluation pipelines, chunking optimization, query rewriting and cost monitoring from day one.

Whether you’re building an internal knowledge assistant, a customer-facing Q&A system or a compliance document search — we’ve shipped these systems and know where the pitfalls are.

Why Vibranium Bytes

Why build with us

Evaluation-First Approach

We build evaluation pipelines before the RAG system. Every change is measured against golden datasets so you always know if quality improved or regressed.

Chunking Optimization

We test semantic, recursive and fixed-size chunking strategies against your data. The right chunking strategy can improve retrieval accuracy by 40%.

Cost Monitoring Built-In

Semantic caching, model routing and token optimization from day one. We track cost per query and alert before budgets are exceeded.

Hallucination Guardrails

Every response is validated against source documents. Low-confidence answers are flagged for human review, not surfaced to users.

Capabilities

What we build with RAG Development & Evaluation

Vector Database Setup

Pinecone, Weaviate, Qdrant or pgvector — we pick the right one for your scale and deploy it.

Query Rewriting

User queries are rewritten and expanded for better retrieval. Multi-query and HyDE strategies tested against your data.

Reranking Pipeline

Cross-encoder reranking of retrieved documents ensures the most relevant context reaches the LLM.

Evaluation Dashboard

RAGAS metrics (faithfulness, relevance, recall) tracked over time with regression alerts on every deployment.

FAQ

Frequently asked questions

RAG (Retrieval-Augmented Generation) combines a search system with an LLM. You need it when you want AI to answer questions about your own data — documents, knowledge bases, or databases — without fine-tuning a model.

We use a combination of retrieval metrics (recall@k, MRR), generation metrics (faithfulness, relevance via RAGAS framework), and business metrics (cost per query, latency, user satisfaction). We build evaluation into the CI/CD pipeline.

We have production experience with Pinecone, Weaviate, Qdrant, pgvector and ChromaDB. The choice depends on your scale, latency requirements and existing infrastructure.

We implement semantic caching (cache similar queries), intelligent chunking (reduce token usage), model routing (use cheaper models for simple queries), and monitoring dashboards so costs never surprise you.
