Hi @momo0101 ,

Unfortunately we can't help you enable it. This endpoint needs to be manually enabled by Databricks for your workspace. 
You have 2 options:

- wait until Anthropic will resolve capacity issues and then this endpoint will be again available for all customers

- create support ticket and asked them to enable it for you 

They replied that your account has not purchased any support contracts. Could you ask your Databricks account admin to check again? You might actually have support contracts, but they are probably associated with the account that first created Databricks in your tenant (most likely your Azure tenant admin).
