Two ways to get GPU power
Running a self-hosted model takes a GPU, and there are two ways to get one: rent it in the cloud and pay for the time you use, or buy your own server and pay once for the hardware. The question is never “which is better in general” — it is which one costs less at your workload and meets your data requirements.
The money, side by side
| Criterion | Rented GPU | Your own server |
|---|---|---|
| Getting started | cheap, no capital outlay | one-off investment |
| Under steady load | expensive, billed every month | pays for itself in 12-18 months |
| Control over data | depends on the provider | full, inside your perimeter |
| Scaling and flexibility | add capacity in minutes | scale by adding hardware |
| Works offline | no | yes (air-gapped) |
When each option makes sense
- •Rent: pilots, one-off jobs, spiky or unpredictable load, and any situation where capital spend is not on the table.
- •Own: continuous work, sensitive data under regulatory or trade-secret rules, dozens of users, and independence from any provider.
For the broader three-year cost comparison between self-hosted and cloud AI, see on-premise LLM vs cloud AI. For the build itself, there is a step-by-step guide to building an AI server.
How we handle it
We support both paths: rented capacity on our own site for the pilot, and a turnkey server build for production, carrying over everything you set up during the trial. More on the on-premise AI server page.
Frequently asked questions
Is renting a GPU cheaper than buying one?
At the start, and for irregular workloads, yes. But once the load is steady, rental overtakes purchase quickly: within a year to eighteen months you have paid out the price of a server, and a server keeps running for years after that. Where the break-even lands depends on how heavily you use it.
Does renting a GPU solve data-residency requirements?
That depends on the provider and where the machines physically sit. If the data centre is in the right jurisdiction and nothing crosses a border, the transfer question goes away — but you still do not have full control of the infrastructure. Maximum control comes from your own hardware inside your own perimeter.
What should we use for a pilot?
Rental is convenient for testing a hypothesis: fast to start, no capital outlay. Once you have confirmed the solution works and the load is constant, you move onto your own hardware. We support both and help with the transition.
