What is air-gapped AI, and how do you deploy it?

Air-gapped AI runs models and the platform around them on networks with no internet connection. What truly air-gapped means, and the steps to deploy it.

Last updated · Fusionative

Short answer

Air-gapped AI is AI infrastructure, models and the platform around them running on a network physically or logically isolated from the internet. Everything, from container images and model weights to licenses, updates and monitoring, must work without reaching an outside service, and moves in only through controlled transfer.

What truly air-gapped requires

  • No call-home dependency: licensing, telemetry and the control plane work offline.
  • A private container registry and package mirrors inside the boundary.
  • Model weights imported, scanned and verified before use.
  • Updates delivered as signed bundles through approved transfer media.
  • Local identity, certificates, logging and monitoring.

Deployment steps

  • Prepare an offline bundle on a connected staging system: platform images, Helm charts, OS packages, drivers and models.
  • Scan and sign the bundle, then transfer it through the approved process.
  • Load images into the internal registry and install the platform from it.
  • Import models into the internal catalog and approve them for tenants.
  • Repeat the bundle process for each update; keep a record of what entered the boundary.

Where FusioNative fits

FusioNative's Deployment Engine installs from air-gapped bundles into a local Harbor registry with offline license files; the LLM gateway has no cloud egress by default; and FusionVault can export and import backups across the air gap. Tenancy, quotas, metering and security work as in connected installs.

FAQ

Frequently asked questions

Can large language models run fully offline?

Yes. Open-weight models can be served offline with runtimes such as vLLM, SGLang or Ollama on local GPUs. Only the initial transfer of model files crosses the boundary.

Who needs air-gapped AI?

Defense, intelligence, critical infrastructure, some government and financial workloads, and any environment where data must not touch the internet.

How are air-gapped systems kept up to date?

With periodic signed update bundles brought in through a controlled process, plus internal mirrors for packages, images and vulnerability databases.

Is air-gapped the same as on-premises?

No. Many on-premises systems are still connected to the internet. Air-gapped means no connection at all, or only a tightly controlled one-way transfer.
