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

Allowlist request for gemini-3-pro-image (GA) on Vertex AI

Please enable the GA image model gemini-3-pro-image on our project.

  • Project ID: (PII Removed by Staff)
  • Project number: (PII Removed by Staff)
  • Model: gemini-3-pro-image (the GA build of Gemini 3 Pro Image)
  • Endpoint: Global (aiplatform.googleapis.com)
  • Region: we call the Global endpoint, no regional pin needed

We already run the preview model gemini-3-pro-image-preview in production on this project for AI assisted ad creative (product image compositing for an EU health supplement brand). We want to move to the GA model for the production SLA and the stable model id. Please also confirm whether gemini-3.1-flash-image GA is available to the same project, as we use the flash tier on a fallback path.

Thank you.
