Anthropic Claude quota stuck at "0 to 0" — request manual model-access review

My project cannot access Anthropic Claude models on Vertex AI. All quotas are
“0 to 0” and the console says “you are not eligible for a quota increase at this
time”, so the self-service quota request is auto-rejected.

Please help with a manual model-access / eligibility review.

  • Project ID: (PII Removed by Staff)
  • Project number: (PII Removed by Staff)
  • Billing account: (PII Removed by Staff)
  • Model: anthropic-claude-opus (Claude Opus 4.8), also anthropic-claude-sonnet
  • Region: global (us-east5 as fallback)
  • API enabled: yes; model enabled in Model Garden: yes (Opus 4.8)
  • Error on test call: HTTP 429 RESOURCE_EXHAUSTED — “Quota exceeded for
    aiplatform.googleapis.com/global_online_prediction_requests_per_base_model
    with base model: anthropic-claude-opus”
  • Use case: personal/analytics use via Claude Desktop and API

Could a Googler please route this to the Vertex AI model-access team for a
manual review? Thank you.
