Private & Offline LLMs

Your own LLM, inside your own perimeter.

Fine-tuned open models served in your VPC, on-premise or fully air-gapped — zero data egress, full residency control, and lower cost than API calls.

What We Deliver

Everything needed to run LLMs where your data lives.

A complete self-hosted stack — models, serving, security and operations — with the economics of owning instead of renting.

Self-hosted deployment

On-premise, VPC or fully air-gapped — the model runs where your data already lives, with zero egress.

Quantization

INT4 / INT8 quantized models cut memory and cost while keeping quality — more throughput per GPU.

Fine-tuning

LoRA and QLoRA adapters tune open models to your domain — trained on your data, kept as your asset.

Secure gateway

An inference gateway with RBAC, rate limiting and audit logging — every request accounted for.

Low latency

In-VPC inference with autoscaling — no internet round-trip, no rate limits you don't set yourself.

Safe upgrades

Blue-green rollouts and instant rollback — model upgrades on your schedule, never a vendor's.

Reference Architecture

How a private LLM stack works.

Self-hosted, quantized models running in your VPC or data center — behind an inference gateway with RBAC and full observability.

Stage 01 — Control every request

Gateway

All traffic enters through a secure inference gateway that enforces who can ask what, and logs everything.

  • RBAC & SSO integration
  • Rate limiting & quotas
  • Full audit logging
Stage 02 — Inference on your GPUs

Serve

Quantized open models run on vLLM with continuous batching — high throughput and low latency on your own compute.

  • vLLM / Triton serving
  • INT4 / INT8 quantization
  • LoRA adapters per domain
Stage 03 — Answer from private data

Ground

RAG over your internal documents keeps answers accurate — and the knowledge base never leaves the perimeter either.

  • In-perimeter vector store
  • RAG over policies, SOPs & manuals
  • Role-scoped knowledge access
Stage 04 — Run it like production

Operate

Autoscaling, monitoring and blue-green upgrades keep the stack healthy — online, in your VPC, or fully air-gapped.

  • Kubernetes autoscaling
  • Blue-green rollouts & instant rollback
  • Latency, cost & GPU dashboards

A secure, self-hosted LLM stack — gateway, quantized serving, GPU compute and private data, air-gap capable end to end.

Engagement

What you get, and when.

A fixed-scope path from compliance requirements to a model serving inside your perimeter.

Week 1–2

Sizing & compliance audit

We assess your workloads, GPU options and residency requirements, and select the right open model and quantization.

Week 3–4

Working pilot

A quantized model serving real queries in your VPC or on-prem environment, benchmarked for latency and cost.

Month 2

Production

Gateway, monitoring and upgrade process in place — including air-gapped operation where required.

Case Studies

Financial Services · India
62%Lower cost
140msP95 latency
0Data egress
Challenge

Sensitive customer and policy data made public LLM APIs a compliance non-starter, blocking a much-needed internal copilot.

Approach

Deployed a quantized (INT4) open-weight model in the client VPC with RAG over policy documents, an RBAC inference gateway and full audit logging.

Impact

A secure copilot for 800+ staff with zero data egress and predictable, capex-friendly economics.

Air-Gapped · Manufacturing

Private Multi-Agent Operations Assistant

Industrial Manufacturing · APAC
70%Queries auto-resolved
4h/wkSaved per engineer
100%Offline capable
Challenge

Plant engineers lost hours searching SOPs, manuals and maintenance logs — often on air-gapped shop-floor networks.

Approach

Built a multi-agent system — retriever, planner, tool-executor — on a self-hosted model, running offline at the plant edge with role-scoped knowledge.

Impact

Instant, grounded SOP guidance with no cloud dependency and controlled model upgrades.

Technology Stack

Built on proven serving infrastructure.
