/ RAG Development

RAG development for LLMs that know your business.

Retrieval-augmented generation — done right. Chunking, embeddings, hybrid search, reranking and evals — so your AI answers from your data, not from the internet's guesses.

/ In short

RAG (retrieval-augmented generation) development is the engineering of AI systems that combine a large language model with a search over your own data — using embeddings, vector databases, hybrid retrieval and reranking — so the model answers grounded in your documents.

/ What this service includes

What we deliver with RAG Development Services.

01
Document RAG

PDFs, Notion, Confluence, Drive, SharePoint, SQL.

02
Hybrid retrieval

Vector + BM25 + reranker — not just cosine similarity.

03
Evals & quality

Golden sets, regression tests, human review loops.

04
Multi-tenant RAG

Per-tenant indexes with strict isolation.

05
On-prem RAG

Fully local with open models and local vector DBs.

/ Is this right for you?

Honest fit check.

A plain answer up front. We'd rather not sell you something you don't need.

Yes if
  • Your LLM answers need to come from your documents, not the internet
  • You need sources cited on every answer
  • You care about accuracy evals on a real golden set
× Not a fit if
  • You only need creative writing — RAG isn't what you need
  • You want fine-tuning only — see LLM Integration or ML
  • You won't do quality review or eval work — it's how RAG stays good

/ Comparison

RAG vs fine-tuning vs long context

Your need
Recommended
Knowledge that changes often
RAG
Consistent tone / format
Fine-tuning
One huge document per query
Long-context LLM
Private data, must stay on-prem
RAG with open models
Best overall for support/KB bots
RAG (often + light fine-tune)
/ Pricing & timeline
Typical range
From $700 (scope-dependent)
Timeline
5 – 16 weeks
Team shape
1 AI lead · 1–2 engineers · 1 domain expert (client-side)

Starting from $700, depending on project scope and requirements. On-prem deployments with open models are scoped separately from SaaS-LLM builds.

/ Why us

What makes us different.

01
Senior engineers stay on the work

The people you meet in discovery stay involved through architecture, delivery and launch.

02
Search, performance and accessibility are built in

Metadata, schema, page performance and semantic markup are part of delivery, not a post-launch add-on.

03
Architecture is explained in writing

Tradeoffs, integrations and scope changes are documented so your team can audit decisions later.

04
Your team owns the output

Repos, infra, analytics and documentation live in your accounts from the beginning.

/ FAQ

Frequently asked questions

RAG for knowledge that changes. Fine-tuning for style, format or tight latency. Often both.

Usually: bad chunking, embedding-only retrieval (no BM25, no reranker), no evals, no source-attribution. Fixable.

Yes — Llama / Mistral + local vector DB + your own GPUs or CPU-only for smaller models.

We test multiple strategies — fixed-size, recursive, semantic and document-aware chunking — and pick the one that scores highest on your golden eval set. There is no universal best approach.

Yes — we ingest PDFs, Word docs, Notion, Confluence, Google Drive, SharePoint, SQL databases and structured APIs into a unified retrieval layer.

Separate vector indexes or strict metadata filtering per tenant so each customer's data is isolated, searchable only by their users, and never cross-contaminated.
