# Private AI / Local AI Deployment

Running AI models on your own infrastructure instead of sending data to third-party cloud APIs.

## Definition

Private AI (or local AI deployment) means running AI models on your own infrastructure — on-premises servers or your own cloud instances — instead of sending data to third-party APIs like OpenAI, Google, or Anthropic.

This approach uses open-source models (like Llama, Mistral, or Phi) that can be downloaded, customized, and [fine-tuned](/glossary/fine-tuning) for your specific domain. The key difference: your data never leaves your environment. Nothing gets sent to an external server. Nothing gets used to train someone else''s model.

Private AI has matured rapidly. Models that required data center hardware two years ago now run on a single server or even a high-end laptop. The performance gap between private and cloud-hosted models is narrowing, especially for specific business tasks after fine-tuning.

It connects to your broader AI architecture alongside cloud APIs and [RAG (Retrieval-Augmented Generation)](/glossary/rag-retrieval-augmented-generation) systems. Many companies use a hybrid approach: private AI for sensitive data and specialized tasks, cloud APIs for general-purpose capabilities where data sensitivity is lower.

[AI governance](/glossary/ai-governance) frameworks should define when private AI is required versus when cloud APIs are acceptable.

## Why It Matters for Middle Market Companies

If you''re in a regulated industry — healthcare, finance, legal, government contracting — or handle sensitive customer data, private AI eliminates the core data privacy concern that blocks AI adoption. Your data stays yours.

Beyond privacy, private AI gives you predictable costs (no per-token API fees), reduced vendor dependency, and the ability to customize models for your exact needs. When you''re running thousands of AI operations daily, the economics shift heavily in favor of private deployment.

The tradeoff is higher upfront investment in infrastructure and expertise. But for companies processing sensitive information at scale, it''s often the only responsible path forward.

Our [AI enablement services](/services/ai-enablement) help companies evaluate whether private AI makes sense for their use cases and implement it when it does. Take the [AI Quotient Assessment](/ai-quotient) to get a recommendation based on your specific data sensitivity and volume requirements.
