What is an AI computer?
On-prem hardware that runs your own models inside your environment, the appliance behind sovereign, private AI.
In short
An AI computer is an on-premise appliance, hardware plus software, that runs your own AI models inside your environment, trained on your data, with nothing leaving the building. It replaces calling a model over the internet with running an owned model locally.

How an AI computer works
An AI computer combines three things in one place: GPU hardware sized to your model, the model itself (ideally one you own and that's trained on your domain), and an application layer, chat, API, and a usage platform, so your team can actually use it.
Because all three run locally, every prompt, document, and answer stays inside your perimeter. There is no external API call and no data leaving your network.
How is an AI computer different from cloud AI?
Cloud AI sends your data to a model on someone else's servers and bills per token forever. An AI computer keeps everything local for a fixed cost, and you own the model.
Who needs an AI computer?
Any organisation that can't send sensitive data to an external API: regulated enterprises, government and defence, finance, healthcare, and research labs, especially those needing air-gapped operation.
Meet Locai One
Locai One is Locai Labs' AI computer: a fixed-cost on-prem appliance that bundles a sovereign model, serving, and an application layer, so you get on-prem control without building the stack yourself. Learn more on the Locai One page.
AI computer vs cloud AI
| AI computer (on-prem) | Cloud AI (API) | |
|---|---|---|
| Where data goes | Stays in your building | Sent to the provider |
| Cost model | Fixed, owned asset | Per-token, recurring |
| Control | You own the model | You rent access |
| Latency | Local, predictable | Network-dependent |
| Internet required | No (air-gap option) | Yes |
What this looks like with Locai
An AI computer is only as useful as what comes inside it, the model, the application layer, and the deployment story.
Locai Labs believes organisations should own their intelligence. Renting access to a general-purpose model that lives on someone else's servers is fine for low-stakes work; for the AI that touches your data, your customers and your decisions, the model itself should be yours. That is the bet behind everything we build.
It is also a bet that an expert model beats a generalist on the work that actually matters to your business. A smaller model trained on your data, your language, your workflows and your edge cases routinely outperforms much larger generalists on the tasks you care about, and it does so on infrastructure you control. The goal is not the biggest model; the goal is the right model for your business.
And it is deployed sovereignly: an owned model that runs inside your perimeter, on-prem via Locai One, in your private cloud tenant, in a UK sovereign cloud, or fully air-gapped, depending on your residency and security requirements. Your prompts, your documents and your outputs stay inside your environment, under UK jurisdiction, with a data path designed to fit GDPR and the procurement standards regulated organisations are held to.
Frequently asked questions
What is an AI computer?
An on-prem appliance that runs your own AI models locally, hardware, model, and apps in one, so your data never leaves your environment.
How is it different from a normal server?
It's purpose-built for AI: GPU hardware sized to the model, a model trained on your data, and an application layer to use it, delivered as a ready-to-run solution.
Do I need internet to use one?
No. An AI computer can run fully air-gapped with no external connection, which is why it suits the most sensitive environments.
What does an AI computer cost?
It's a fixed cost rather than a per-token bill. See our on-prem AI cost guide for a breakdown and the API cost crossover.
