On-Premise & Private LLM Deployment

Enterprise-grade AI on your own infrastructure — your data never leaves your network

Deploy self-hosted, open-source LLMs (Llama, Mistral, Qwen, GPT-OSS-class 120B models) on your own servers, private cloud, or air-gapped infrastructure — with the retrieval, guardrails, and monitoring stack to run them in production. Proven at national-government scale.

Key Benefits

Zero data leaves your network — full data sovereignty
No per-token API costs — predictable infrastructure economics
Proven at national-government scale (MoSPI, Govt of India)
Air-gapped deployment capability for classified environments
Your team can operate it — full documentation and training included

Deep Dive: On-Prem LLM

01

For government agencies, defence, BFSI, healthcare, and any enterprise with strict data residency requirements, sending data to OpenAI or Anthropic APIs is a non-starter. We design and deploy fully self-hosted LLM stacks — models, inference servers, vector databases, and application layers — that run entirely within your network perimeter, including air-gapped environments.

02

This is not theoretical for us. For the Ministry of Statistics and Programme Implementation (Government of India), we deployed a self-hosted 120B-parameter open-source LLM (o3-class reasoning quality) with Qdrant vector search, BGE embeddings, and Docling document processing — serving RAG queries over 10,000+ national statistical documents on secure government infrastructure, with zero external API calls.

03

We handle the full deployment lifecycle: model selection and benchmarking against your quality bar (Llama 3, Mistral, Qwen, DeepSeek, GPT-OSS 120B), GPU sizing and procurement guidance, quantization for your hardware budget (INT4/INT8, GGUF, AWQ), inference serving with vLLM or TGI for production throughput, and horizontal scaling as usage grows.

04

Beyond the model itself, production on-prem AI needs the full stack: authentication and role-based access control, prompt/response logging for audit, PII handling, content guardrails, monitoring and alerting, and update pipelines for new model versions. We deliver all of it — Dockerized, documented, and maintainable by your own team.

Key Features & Capabilities

Everything included in our On-Prem LLM service offering.

01

Model Selection & Benchmarking

Rigorous evaluation of open-source models (Llama, Mistral, Qwen, DeepSeek, GPT-OSS 120B) against your specific tasks, quality bar, and hardware budget before committing.

02

GPU Infrastructure Design

Right-sized GPU recommendations (A100/H100, L40S, or consumer-grade for smaller models), cluster architecture, and cost projections — buy exactly what you need, no more.

03

Production Inference Serving

vLLM / Text Generation Inference deployment with continuous batching, quantization (INT4/INT8, AWQ, GGUF), KV-cache optimization, and load balancing for real throughput.

04

Air-Gapped & Secure Deployment

Fully offline installation for classified or regulated environments — model weights, embeddings, containers, and updates delivered without internet dependency.

05

Complete RAG Stack On-Prem

Self-hosted vector databases (Qdrant, Weaviate, pgvector), embedding models (BGE, E5), and document processing (Docling) — the full retrieval pipeline inside your network.

06

Frequently Asked Questions

Common questions we hear about on-prem llm engagements.

Which open-source LLMs can match GPT-4-class quality on-premise?
For most enterprise tasks, current-generation open models — Llama 3.3 70B, Qwen 2.5 72B, DeepSeek V3, and GPT-OSS-class 120B models — deliver quality comparable to proprietary APIs, especially when paired with a well-built RAG pipeline. We benchmark candidate models on your actual tasks during discovery, so the decision is data-driven rather than hype-driven.
What GPU hardware do we need to run an LLM on-premise?
It depends on model size and concurrency. A quantized 70B model serves a small team on 2× A100 80GB or 4× L40S; a 120B model at government scale typically needs 4–8× A100/H100. Smaller 7–14B models run on a single consumer-grade GPU for lighter workloads. We provide exact sizing and cost projections before you buy anything.
Can this work in a fully air-gapped environment with no internet?
Yes. We deliver model weights, container images, embedding models, and all dependencies as offline installation bundles, and define an update process that works within your security procedures. We have deployed on secure government infrastructure where external API calls are prohibited.
How does on-prem cost compare to using OpenAI or Anthropic APIs?
APIs win at low volume; on-prem wins at scale and on data sovereignty. As a rule of thumb, sustained workloads above a few million tokens per day usually break even on GPU investment within 12–24 months — and for regulated data, on-prem is often the only compliant option regardless of cost. We model your specific economics during scoping.
Who maintains the system after deployment?
Your team, if you want — every deployment includes runbooks, admin training, and full documentation so you're not locked into us. Most clients keep a light support retainer for model upgrades and optimization, but independence is the design goal.
