Claude Sonnet 4.6 and Opus 4.6 QUOTA stuck at 0 — increase requests automatically rejected

Hi,

I’m trying to use Anthropic Claude models (Sonnet 4.6 and Opus 4.6) on Vertex AI, but the quota for both models is locked at 0.

Project ID: —-

Region: global

Models: anthropic-claude-sonnet-4-6, anthropic-claude-opus-4-6

Billing: Active paid account

Vertex AI API: Enabled

Model Garden: Both models enabled

When I try to request a quota increase through the Quotas page, it is automatically rejected within minutes with no explanation. The allowed range shows “0 to 0” for some quotas.

Our team is evaluating Claude models for integration into internal chatbot and agentic workflows. We only need a minimal initial quota (RPM: 60, TPM: 100,000) to conduct a Proof of Concept.

Could someone from Google manually review and unblock our project? Thank you.

I have the same issue. Project: (PII Removed by Staff). Models: claude-opus-4-6, claude-sonnet-4-6. Region: us-east5. Billing is active paid account upgraded from free trial. All Claude quotas show range 0 to 0, cannot increase via console. Please help.

Hey Nick!

Since you’re dealing with the same issue as me, I wanted to share what the Google Cloud support team told me!

They said there isn’t sufficient payment history on record, and that small payments or manual payments may not meet the requirements for a quota increase.

Hope this helps!

I have the same issue.

Need minimal quota for PoC: 60 QPM / 100K TPM.

Please advise on how to get manual review.
