# Air-Gapped Deployment

> Run Bifrost in environments without outbound internet access.

## Overview

Bifrost fetches its pricing and model parameter datasheets from `https://getbifrost.ai/datasheet` on startup and periodically in the background. In environments without outbound internet access, these fetches fail and Bifrost cannot start.

Both fields accept `file://` URLs so you can load the datasheets from the local filesystem instead.

***

## Setup

**1. Download the datasheets** on a machine with internet access:

```bash theme={null}
curl -o pricing.json https://getbifrost.ai/datasheet
curl -o model-parameters.json https://getbifrost.ai/datasheet/model-parameters
```

Transfer the files to your air-gapped host (or bake them into your container image / Kubernetes volume).

**2. Point Bifrost at the local files** in `config.json`:

```json theme={null}
{
  "framework": {
    "pricing": {
      "pricing_url": "file:///opt/bifrost/pricing.json",
      "model_parameters_url": "file:///opt/bifrost/model-parameters.json",
      "pricing_sync_interval": 86400
    }
  }
}
```

<Note>
  `file://` URLs require three slashes followed by an absolute path.
</Note>

**3. Ensure the files are accessible** to the Bifrost process at the configured paths before starting.

***

## Keeping datasheets current

Bifrost re-reads the file on every sync tick (`pricing_sync_interval`, minimum 3600 s).
