Hi @samuel86,

I can see from the thread that you have already done quite a bit of due diligence here -- Premium workspace, eastus2 region, geo enforcement disabled, and sufficient Azure GPU quota. Let me help you work through this systematically.

Your region (eastus2) does fully support provisioned throughput, GPU model serving, and Foundation Model APIs on Azure Databricks, so the region is not the issue. Here is what to check next:

VERIFY SERVERLESS COMPUTE IS ENABLED

Provisioned throughput requires serverless compute. On Azure Databricks, serverless compute has these requirements:

1. Unity Catalog must be enabled on the workspace. If your workspace was created without Unity Catalog, you need to enable it first. You can verify by checking whether you see the "Catalog" icon in the left sidebar.

2. The workspace must not have PCI-DSS enabled in the compliance security profile.

To confirm serverless compute is working, try creating a Serverless SQL Warehouse (go to SQL Warehouses, click Create, and select "Serverless" as the type). If that works, serverless compute is enabled. If it fails, that is the root cause.

CHECK ACCOUNT CONSOLE SETTINGS

As a workspace admin, go to the Databricks Account Console at https://accounts.azuredatabricks.net/ and check:

1. Click on your workspace name, then the "Security and compliance" tab.
2. Confirm that "Enforce data processing within workspace Geography for Designated Services" is disabled (you mentioned you have already done this -- just double-checking).

VERIFY YOUR WORKSPACE TIER

You mentioned a "premium account" which is great. Just to confirm, navigate to Admin Settings in your workspace and check that the pricing tier shows "Premium." Provisioned throughput is not available on Standard tier or the free trial/Community Edition.

TRY THE PAY-PER-TOKEN ENDPOINTS FIRST

While troubleshooting, you can verify that Model Serving works at all by trying the pay-per-token Foundation Model APIs. These are preconfigured endpoints that appear automatically in the Serving tab (left sidebar). Look for endpoints like "databricks-meta-llama-3-3-70b-instruct" or similar at the top of the Serving endpoints list. If pay-per-token endpoints work but provisioned throughput does not, that narrows the problem significantly.

IF EVERYTHING CHECKS OUT BUT THE ERROR PERSISTS

If all the above settings are correct and you still receive the "Provisioned throughput is not enabled for this workspace" error, then there may be an account-level entitlement that needs to be activated. Here are the best ways to reach the Databricks team for this:

1. In-workspace help: Click the "?" icon in the top-right corner of your Databricks workspace, then select "Support." This opens the Databricks Help Center directly from within the workspace and should let you file a support request.

2. Azure support: Since you are on Azure, you can also open a support request through the Azure Portal. Go to the Azure Portal, find your Azure Databricks resource, and click "New support request." Azure routes Databricks-specific tickets to the Databricks support team.

3. Contact form: If the above options do not work, the contact form at https://www.databricks.com/company/contact can connect you with a representative.

4. This community: You can also tag Databricks Community Managers here who may be able to escalate on your behalf.
