    Welcome to Microsoft Q&A

    Hello @Pentose I hope you are doing well.

    The error:

    715-123420: Our system has detected this request as unusual activity for your account.

    typically indicates that the request was blocked by Microsoft's automated security or fraud detection systems, rather than an issue with the model itself or your deployment configuration.

    A few things you can check:

    • Verify that your Azure AI Foundry project, Azure AI Services resource, and subscription are all in good standing and have no restrictions.
    • Try deploying a different supported model or deploy the same model in another supported region to determine whether the issue is region-specific.
    • Ensure that you're signed in with the correct tenant and subscription, and that your account has the required permissions (such as Owner or Cognitive Services Contributor) on the Azure AI resource.
    • If you've recently created the subscription or made a large number of deployment requests in a short period, temporary security protections may have been triggered. Waiting for a period of time and retrying may resolve the issue.
    • Since this error specifically references unusual activity detection, it is generally a platform-side validation rather than a deployment configuration problem.
