Services / RAG & LLM development

RAG and LLM development services that cite their sources.

We build retrieval-augmented generation systems and custom LLM applications on your own data: permission-aware, measured for accuracy, and ready to grow into agents that act.

Trusted on five-year contracts by a leading Indian bank and a Dubai government entity.

What is RAG development?

Answers grounded in your data, not the model's memory.

RAG development is building systems that retrieve relevant passages from an organisation's own documents and data at query time, then have a language model answer using only that material, with citations. It keeps answers current and checkable without retraining the model.

What does an LLM development company do?

An LLM development company designs, builds and runs applications on large language models: choosing the model, connecting it to company data through RAG, fine-tuning where it helps, measuring quality with evaluations, and operating it securely in production, often on private infrastructure.

01 / RAG patterns

Five RAG patterns, chosen per problem

Naive RAG

Chunk, embed, retrieve the top matches, generate. A fast baseline for small, clean corpora.

Hybrid search

Keyword and vector search combined, so exact terms like product codes are never missed.

Reranking

A second model reorders results by relevance before generation, lifting answer quality.

GraphRAG

Retrieval over a knowledge graph of entities and relations, for questions that span many documents.

Agentic RAG

An agent plans its searches, checks results and retrieves again until the answer is supported.

02 / LLM development services

Everything around the model, not just the prompt

Model selection

Claude, GPT, Llama and other models compared on your tasks for quality, cost, latency and policy.

Fine-tuning and LoRA

Adapting models to your domain, format or tone when prompting and retrieval are not enough.

Distillation

Training smaller, cheaper models from larger ones for high-volume or edge workloads.

Evaluations

Test sets built from real questions, scoring accuracy, grounding and safety before every release.

LLMOps

Versioned prompts and models, monitoring, cost tracking and feedback loops in production.

03 / Choosing an approach

RAG, fine-tuning or long context?

Most enterprise systems combine them. This is how we decide where to start.

FreshnessUpdates as soon as sources changeFixed until the next training runCurrent for whatever you paste in

04 / Enterprise-grade

What makes RAG safe for the enterprise

Permission-aware retrieval

Documents are filtered by each user's existing access rights before anything reaches the model, so no one sees what they couldn't open.

Freshness

Incremental indexing keeps answers aligned with the latest policy, contract or product version, with sources dated.

Citations

Every answer links to the passages it used, so reviewers and auditors can check it in seconds.

Hallucination evals

Automated grounding checks flag claims the sources don't support, before release and continuously in production.

05 / What we build with

Your models, your data, your cloud

MODELS

Claude, GPT, Gemini, Llama, Mistral and other open-weight models.

Model-agnostic, so you can switch without rebuilding.

RETRIEVAL

pgvector, Pinecone, Weaviate, Elasticsearch and OpenSearch.

Plus knowledge graphs from ElixirData Context OS.

FRAMEWORKS

LangChain, LlamaIndex, LangGraph and MCP.

Deployed on AWS, Azure, private cloud or on-prem.

06 / From RAG to agents

Start by answering. Grow into acting.

1 · Answer

RAG assistants answer questions with citations. Low risk, fast value.

2 · Recommend

The system suggests an action, such as a refund or a ticket route, and a person approves it.

3 · Act

Agents take bounded actions in your systems, with decision boundaries and a decision trace. See AI agent development.

The retrieval layer, evals and permissions you build for RAG carry straight into agents, so nothing is thrown away. Starting with a conversational front end? Talk to us about AI chatbot development.

07 / How we build

From first question to production

PHASE 1

Discover

Pick the questions, sources, users and the quality bar.

PHASE 2

Build the index

Connect sources, chunk, embed and apply access rights.

PHASE 3

Evaluate

Score answers on a test set from real questions.

PHASE 4

Pilot

Release to a user group and collect feedback.

PHASE 5 · ONGOING

Scale and run

Monitor quality and cost, add sources, extend to agents.

FAQ

RAG and LLM development, answered

How much do RAG development services cost?

Cost depends on the number and type of sources, access-control complexity, quality targets and where it is hosted. A scoped pilot on one use case is the fastest way to a firm number.

Should we use RAG or fine-tune a model?

Use RAG when answers must come from large or changing knowledge, with citations and access control. Fine-tune when you need a consistent style, format or narrow skill. Many production systems use both.

How do you stop the model from making things up?

Answers are generated only from retrieved passages, cited, and checked by automated grounding evaluations before release and in production.

Can a RAG system respect our document permissions?

Yes. Retrieval filters results by each user's existing access rights, so the model never sees content the user couldn't open.

Which LLMs do you work with?

Claude, GPT, Gemini, Llama, Mistral and other open-weight models, chosen per task on quality, cost, latency and policy.

Can the LLM run on our own infrastructure?

Yes. We deploy open-weight models on your private cloud, on-prem or sovereign infrastructure when data can't leave your environment.

How long does a RAG project take?

A pilot on one use case typically comes first, followed by scaling to more sources and users. Timeline depends on source readiness and access rules, and is set during scoping.

Who owns the system you build?

You own your data, indexes, prompts and configurations. Engagement IP terms are confirmed in the statement of work with your legal team.

Scope your RAG system in one call.

We'll pick the use case, map the sources and access rules, and agree the quality bar your answers must meet.
