You will need the following:

Setup

First, decide how to reference your Account ID and API token (either directly in your .env.local using the CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN variables or in the endpoint configuration).

When setting up your models, specify the cloudflare endpoint.

  "parameters": {
    "stop": ["<|im_end|>"]
  },
  "endpoints" : [
    {
      "type": "cloudflare",
      // optionally specify these if not included in .env.local
      "accountId": "your-account-id",
      "apiToken": "your-api-token"
      //
    }
  ]
}
