So … When will Vertex AI open Claude Sonnet 3.5 V2? The quota is always 0. I wonder if your servers are made of potatoes 
I have the same issues and request for quota are rejected.
Hello,
We have received your quota request for XXXXXX.
Unfortunately, we are unable to grant you additional quota at this time. If this is a new project please wait 48h until you resubmit the request or until your Billing account has additional history.
Your Sales Rep is a good Escalation Path for quota requests, and we highly recommend you to reach out to them. In case you don’t have a dedicated Sales Rep, you can contact[1] our Sales Team.
