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

Hi Google Cloud 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: (PII Removed by Staff)
  • Project Number: (PII Removed by Staff)
  • 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 Google’s
migration email confirming our project used the preview endpoints and
must migrate to GA. We have confirmed gemini-2.5-flash-image works
correctly on this project.

Thank you
