What a private AI server actually needs

When people hear "run the AI on your own hardware," they often picture a server room and a six-figure infrastructure project. For the work most businesses actually do, the reality is a lot smaller than that, and a lot more boring, which is exactly what you want.

A single modern GPU can serve a whole team for private chat and document work. You scale the box to the job, not the other way around.

The model sets the hardware

The main thing that determines what you need is the size of the model you run, and most business tasks do not need a giant one. A compact open model handles private chat, drafting, summarizing, and document Q&A comfortably, and it fits on a single GPU. Step up to a mid-sized model for heavier reasoning across a company, and you are looking at a small multi-GPU box, not a rack of them. Only the largest, frontier-scale open models call for serious iron, and most businesses never need to go there.

What sits on the box

The hardware is only half of it. On top runs an open, well-understood stack: an inference server that serves the model on your GPUs, a gateway that gives your apps one clean endpoint, a vector database for retrieval over your documents, a chat interface your team actually uses, and monitoring so you can see usage and cost. None of it is exotic. All of it runs locally, with nothing phoning home.

Right-sizing, in plain terms

A small practice or team starts with a single-GPU box for chat and document work. A growing company moves to a few GPUs to serve a larger model to everyone. A larger or air-gapped operation runs a bigger build, still measured in a box or two, not a building. You buy the hardware close to cost and own it outright, which means the spend is an asset on your books rather than a subscription that never ends.

You do not have to operate it

The part that stops most teams is not buying a GPU, it is running the stack: sizing it, hardening it, patching it, keeping it fast. That is the part a managed service takes off your plate. You own the box; someone else keeps it healthy. See the full stack and process, compare the tiers, or run the numbers against what you spend on cloud AI today.
