Connect a Cloudflare API token and Account ID to run Decision Judge 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
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

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 evaluator and select this integration.
