# Cloudflare Clef Decision Model

> Add a Cloudflare API token and Account ID to run Decision Judge evaluations on Clef decision models in Arize AX

Connect a Cloudflare API token and Account ID to run [Decision Judge](/docs/ax/evaluate/decision-judge.md) evaluators on Cloudflare's Clef models. Arize AX sends each evaluation to the Clef models in your Cloudflare account.

Cloudflare Clef is a **restricted-use, eval-only** provider: it powers Decision Judge evaluators and does not appear in the prompt playground or Alyx model pickers. It appears in the `/v2/ai-integrations` REST API only when a request filters by provider.

Arize supports these two Clef models:

* `clef` (default)
* `clef-flash`

> [!NOTE]
>
> By adding this integration, your data may be sent to Cloudflare when your Decision Judge evaluators run, and your Cloudflare account will be billed for usage.

## Add the Integration from Arize AX

**Navigate to Settings → AI Providers**, then select **Cloudflare**.

![The Cloudflare integration form with fields for Integration Name, Account ID, and API Token](https://storage.googleapis.com/arize-phoenix-assets/assets/images/arize-docs-images/ai-integration-providers-cloudflare-clef-details.webp)

The Cloudflare integration form

1. Give the integration a **name**, then enter your 32-character **Account ID** and your Cloudflare **API token**. You can find the Account ID under Workers AI › Use REST API in the Cloudflare dashboard. The token needs the Account › Workers AI › Read permission.
2. Accept the terms checkbox.
3. Optionally click **Test Integration**. The test uses `clef-flash`.
4. Save the integration.

Creating an AI provider requires account admin or organization admin access. If role-based access control is enabled for your account, you need the LLM integration create permission at the scope you select. After saving, create a [Decision Judge](/docs/ax/evaluate/decision-judge.md) evaluator and select this integration.
