On-Premise

Where this stands

On-Premise Brain is not generally available. Today Brain runs Levirge-hosted and tenant-isolated, and self-hosting is a conversation we have per organisation rather than a package you can download. This section exists so you can tell us you need it, and so the shape of that conversation is public rather than hidden behind a sales call.

If that is a blocker for you, the honest answer is: register below, and talk to us about timing.

What is already private

Worth separating from deployment, because it is the reason many people ask for on-premise in the first place:

• Hosted model lane — categorisation, summarisation and chat run on models Levirge hosts on its own infrastructure, with no cloud model provider in the path. Embeddings and reranking run on Levirge infrastructure in both lanes.
• Vault isolation — knowledge is partitioned per project, product or client, and Personal Vaults fail closed.
• Tokens you control — per-user workspace tokens you issue and revoke.

That covers "no third-party model sees our data". It does not cover "the data never leaves our network" — that is what on-premise is for.

The two questions

• Requirements — hardware by what you already have, the services around it, and what sizes a deployment.
• Model options — the four inference models, and where each one can run.

The short version: Brain self-hosts on commodity hardware. Search is equally fast with or without a GPU, and the one component that genuinely wants a discrete GPU — reranking — can be turned off, with search falling back to rank fusion.
