# Baseten

The Baseten target adjusts the autoscaling range of one model deployment. Baseten continues choosing the live replica count within that range.

## Configuration

| Field                | Value                                                                        |
| -------------------- | ---------------------------------------------------------------------------- |
| **Model ID**         | The Baseten model that owns the deployment.                                  |
| **Deployment ID**    | The deployment whose autoscaling settings Arklow may change.                 |
| **Credential**       | An [HTTP Auth Headers credential](/resources/credentials/http/auth-headers). |
| **Minimum replicas** | The lowest autoscaling value Arklow may apply.                               |
| **Maximum replicas** | The highest autoscaling value Arklow may apply.                              |

The model and deployment IDs are available in Baseten's deployment details and API URLs.

## Authentication

Create an HTTP Auth Headers credential with the header Baseten expects for its API key:

```text theme={null}
Authorization: Api-Key <api-key>
```

Keep the key in the credential and select that credential when creating the target.

## Observations and changes

Arklow reads the deployment status and active replica count. A deployment in a transitional state, such as deploying or updating, is allowed to finish before another change is applied.

Scale changes update Baseten's minimum and maximum replicas together. The observed active replica count may take time to respond while Baseten provisions or removes replicas.

## Add a Baseten target

<Steps>
  <Step title="Open scale targets">
    Go to [**Scale Targets**](https://app.arklow.io/dashboard/scale-targets), click **New scale target**, and select **Baseten**.
  </Step>

  <Step title="Identify the deployment">
    Enter the **Model ID** and **Deployment ID**.
  </Step>

  <Step title="Select authentication">
    Choose the HTTP Auth Headers credential containing your Baseten API key.
  </Step>

  <Step title="Select capacity">
    Choose the destination or shared pool served by this deployment.
  </Step>

  <Step title="Set the envelope">
    Enter the minimum and maximum replica counts available to the Baseten autoscaler.
  </Step>

  <Step title="Save">
    Create the target and confirm that **Last observed** advances without a credential or deployment error.
  </Step>
