Retrieval-augmented generation

RAG development that ships, and stays honest.

Retrieval-augmented generation built for production: grounded answers, enforced citations, and an eval harness that catches regressions before your users do.

Book a free consultation Read RAG vs fine-tuning

Most RAG demos look great and fall apart in production. We build the version that survives contact with real users and measure it on every change.

What we build

The full retrieval stack, not just a clever prompt.

Document ingestion and chunking pipelines

Tuned to your content and query patterns, not a default 512-token split.

Vector store setup and retrieval tuning

Pinecone, pgvector, or AWS Bedrock, chosen for your scale and budget.

Reranking and citation enforcement

Every answer traces back to a source, or it doesn't ship.

Hallucination guards and escalation

When the system isn't sure, it says so and hands off cleanly.

Delivery approach

The same playbook on every retrieval system we build.

Quality is designed into the pipeline before the first answer reaches a user.
01

Eval harness before the bot

We build a golden dataset before a production prompt. Every chunking change, model swap, and reranker tweak runs through it.

02

Soak before scale

The system reads real queries and drafts answers only your team can see. You grade the drafts, and the disagreements drive tuning.

03

Ship on a canary

Five percent of traffic, then fifty, then full, watching grounding and citation accuracy the whole way.

Where RAG fits

Built to be queried.

  • Support assistants that answer from your real docs, not the open internet
  • Internal knowledge bots for policies, runbooks, and contracts
  • Product search and Q&A grounded in your catalogue or knowledge base
  • AI chatbot and agent systems that need defensible answers
Technical stack

Model-agnostic, by design.

OpenAI, Anthropic, and Google Gemini for generation. LangChain and LlamaIndex for orchestration. Pinecone, pgvector, or AWS Bedrock for retrieval.

Proof

Measured grounding before launch.

The proof is not a flashy demo. It is citations, evals, canaries, and monitored retrieval quality after launch.

FAQ

Things teams ask us first.

Need a clearer answer? Ask directly. We reply within 24 hours.
What's the difference between RAG and fine-tuning?
RAG retrieves your real, current information at answer time and grounds the model in it; fine-tuning bakes patterns into the model's weights. RAG is usually the right first move for knowledge that changes or must be cited; fine-tuning suits fixed style/format needs. Many production systems use RAG, and only add fine-tuning when there's a specific reason.
How do you stop a RAG system from hallucinating?
Grounded retrieval with citation enforcement (every answer traces to a source or it doesn't ship), an explicit "I don't know → escalate" path, and a golden eval set that every change runs through before launch.
Which vector database should we use?
Whichever fits your scale, budget, and stack, Pinecone, pgvector, or AWS Bedrock. The database matters less than the chunking, retrieval tuning, and reranking around it.
How much does a RAG system cost?
It depends on data volume, retrieval complexity, and run costs (embeddings, vector store, inference, monitoring), most quotes skip the last part. We scope your real number, including run costs, in a discovery call.
Can you connect RAG to our existing documents and systems?
Yes, help docs, runbooks, contracts, product catalogues, wikis, and databases, via ingestion and chunking pipelines tuned to your content, not a default split.
How do you know the RAG system is actually accurate?
We build a golden dataset before a production prompt and score every chunking change, model swap, and reranker tweak against it. Grounding and citation accuracy are monitored after launch too.
Which models do you build with?
OpenAI, Anthropic Claude, and Google Gemini for generation; LangChain or LlamaIndex for orchestration. Model-agnostic by design.
How long does it take to build a production RAG system?
Most go live in 2–6 weeks, including ingestion, retrieval tuning, an eval harness, and a monitored soak period.
