RAG systems

RAG development company for grounded, citable AI

Retrieval-Augmented Generation is the most practical way to put LLMs on your private knowledge. We build the full pipeline — ingestion, chunking, embeddings, hybrid search, reranking, generation with citations, and evaluation — so answers stay accurate as your content changes.

Enterprise RAG for knowledge, support, policy, and product documentation teams worldwide.

Why most RAG demos fail in production

Demos ignore messy PDFs, access control, chunk boundaries, and evaluation. Production RAG needs permission-aware retrieval, hybrid lexical + vector search, reranking, citation UX, and continuous measurement of retrieval and answer quality. That operational layer is our focus.

Our RAG architecture approach

We design for your corpus: policies, tickets, wikis, product docs, or multi-tenant SaaS content. Pipelines include incremental ingestion, metadata filters, hybrid retrieval, optional knowledge graphs, and generation policies that refuse when evidence is weak. Deployments can be cloud-managed or private.

Indic and multilingual RAG

Search and answers often fail for Hindi and other Indian languages if embeddings and chunking are English-centric. We build multilingual retrieval experiences — a differentiator for public services, education, and consumer products in India and the diaspora.

Process

How we work

01

Corpus & access audit

Inventory sources, formats, ownership, and who is allowed to see what.

02

Retrieval baseline

Ship a measurable retrieval stack before polishing generation.

03

Answer quality loop

Add generation, citations, and eval sets; tune chunking and reranking.

04

Hardening

Security, observability, fallbacks, and runbooks for ops teams.

Why Tensor Solution

Differentiators

Evaluation-first

We measure retrieval hit-rate and groundedness, not vibes.

Multilingual retrieval

Built for Indic and multi-language corpora, not English-only samples.

Productised search experience

Lessons from shipping GenAI search products inform every RAG build.

FAQ

Frequently asked questions

How much does RAG system development cost?+

Simple internal pilots can start in the low thousands of USD (or equivalent) for a focused corpus. Production multi-source systems with SSO, permissions, evaluation, and SLA-backed ops typically range from mid five-figures upward depending on corpus size, languages, and integrations. We quote after a short discovery.

RAG or fine-tuning?+

Use RAG when answers must reflect changing private documents. Use fine-tuning for style, format, or specialised behaviour. Many systems combine both; we recommend based on your data and risk.

Can RAG run on-premises?+

Yes. We can deploy vector stores, embedding services, and models inside your VPC or on-prem environment when policy requires it.

How do you reduce hallucinations in RAG?+

Strong retrieval, citation requirements, refusal when evidence is weak, answer validation, and ongoing evaluation on real queries — not prompt tweaks alone.
