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: wear-guide
  • GCP Project Number: 3190597060..
  • Organization: niusia.co.jp
  • Region: us-central1
  • Endpoint: global
  • Billing: Enabled (active)
  • Vertex AI API: Enabled
  • Service account: wear-guide-vton
  • Service account role: Vertex AI User

Use case:
Production image generation platform for end users (B2B SaaS).
We are integrating these models into our existing platform that currently
serves customers using virtual-try-on-001 (GA, in production since 2026/02/18).

Expected usage: medium volume (hundreds to low thousands of generations per day).
The new models will replace certain legacy image generation paths to improve
photorealism and enable 4K direct output for enterprise customers.

Thank you for your consideration.

Best regards,
Yukihiro Kashiwaguchi
CEO, NIUSIA CO., LTD.
