Hi Google AI Team,

Requesting allowlist access for the following Vertex AI GA image models:

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

Project details:

  • GCP Project ID: project-5bd6bc17-3e3d-4a72-9..
  • Project Number: 3899883006..
  • Region: us-central1
  • Endpoint: global
  • Billing: Enabled (active)
  • Vertex AI API: Enabled
  • Service account role: Vertex AI User
  • Auth method: Application Default Credentials (ADC)
  • SDK: google-genai (Python)

Use case: Internal image generation tool for a custom LED neon sign
business producing product photography mockups. We received the
Google migration email for these models and have confirmed
gemini-2.5-flash-image works correctly on this project.

Note: We received Google’s migration email indicating our project
used the preview endpoints (gemini-3-pro-image-preview and
gemini-3.1-flash-image-preview) and must migrate to GA.

Thank you
