Allowlist request: gemini-3-pro-image-preview & gemini-3.1-flash-image-preview on Vertex AI

Hi Google AI Team,

Requesting allowlist access for the following Vertex AI preview models on a production project:

  • gemini-3-pro-image-preview
  • gemini-3.1-flash-image-preview

Project details:

  • GCP Project ID: ailabel-4939..
  • Region: us-central1
  • Billing: Enabled (active, paying)
  • Vertex AI API: Enabled
  • Service account role: Vertex AI User (already provisioned)

Use case:
AI image generation platform for Korean creators (/ailabel.kr).
Specifically need gemini-3-pro-image-preview for accurate Korean text rendering
in stylized image effects (handwriting, emoji expressions, captions).

We have already verified end-to-end integration on the GA model gemini-2.5-flash-image

  • image generation working correctly
  • billing and audit logs verified
  • service account permissions confirmed

The only gap is access to the 3 Pro Image preview model, which we need for
production-quality Korean text rendering that 2.5 Flash cannot achieve consistently.

Thank you!
