How do open-source private models compare in quality to GPT-4 or Claude?

The gap between open-source and frontier commercial models has closed dramatically. LLaMA 3.1 405B and Mixtral 8x22B perform comparably to GPT-3.5 and approach GPT-4 performance on many enterprise tasks including document analysis, summarization, question answering, and code generation. For domain-specific tasks where we apply fine-tuning on your proprietary data, private models frequently match or exceed commercial API performance at a fraction of the long-term cost. The right model choice depends on your specific use case, which we evaluate thoroughly during the infrastructure assessment phase.

What GPU hardware is required for on-premise LLM deployment?

Hardware requirements depend on model size and throughput requirements. A quantized 7B model runs effectively on a single NVIDIA RTX 4090 or A10G (24GB VRAM). A 70B model in INT4 quantization requires 2–4 A100 80GB GPUs. A 405B model requires a multi-node A100 or H100 cluster. We design the hardware specification during the assessment phase based on your model quality requirements, concurrent user load, latency targets, and budget — and can work with your existing GPU hardware or advise on new procurement to meet your requirements.

Can private AI systems integrate with our existing enterprise software?

Yes — seamless integration is a core design goal. Our private LLM deployments expose OpenAI-compatible REST APIs, meaning any application built for the OpenAI API works with your private model without modification. We also build custom integration layers for specific enterprise systems — SharePoint, Confluence, Salesforce, SAP, and proprietary internal tools — connecting your private AI platform to the data and workflows where it delivers the most value for your organization.

How long does a private AI deployment project take?

A standard private LLM deployment with RAG pipeline and basic application interface typically takes 4–8 weeks from infrastructure assessment to production go-live. Air-gapped deployments and deployments requiring on-premise fine-tuning pipelines typically take 8–16 weeks depending on environment complexity, security certification requirements, and the scope of application development included in the engagement.

On-Premise & Private AI Deployment Company
All the Power of AI. None of the Data Risk.

Tanθ Software Studio designs and deploys production-grade private AI systems that run entirely within your own infrastructure — your data center, your private cloud, or your air-gapped environment. We self-host and optimize frontier open-source models including LLaMA 3, Mistral, Mixtral, Phi-3, and Qwen on your GPU infrastructure, delivering enterprise-grade AI capabilities with complete data sovereignty, zero third-party data exposure, and no recurring API costs. From GPU cluster setup and model quantization to private RAG pipeline deployment and on-premise fine-tuning, we build the complete private AI stack your enterprise needs.

The Era of Private AI — Enterprise Intelligence Without Data Sovereignty Compromise

As AI becomes mission-critical infrastructure, the organizations with the most sensitive data — healthcare systems, financial institutions, defense contractors, legal firms, and government agencies — face a fundamental dilemma: they need AI capabilities, but they cannot send proprietary patient records, financial transactions, legal strategies, or classified information to third-party cloud APIs. The answer is private AI deployment — the same intelligence, operating entirely within your own controlled environment.

At Tanθ, we specialize in making private AI accessible, practical, and powerful. We have moved past the era where self-hosted AI meant accepting dramatically inferior model quality. Today's open-source models — LLaMA 3.1 405B, Mixtral 8x22B, Qwen2.5, and Phi-3 — match or exceed GPT-3.5 and approach GPT-4 performance on many enterprise tasks. Combined with our expertise in model quantization, GPU optimization, private RAG deployment, and on-premise fine-tuning, we deliver private AI systems that are not just secure — they are fast, accurate, and genuinely capable for demanding enterprise workloads.
