Hello Google AI Team,

I would like to request full allowlist access for my Vertex AI project to enable Gemini 3 Preview models:

Models:

  • gemini-3-pro-image-preview

Project Information:

  • Google Cloud Project: colmobeat-content-factory
  • Use Case: AI content generation platform (text, images, video)
  • Production Environment: Required

Current Status:
I receive 404 NOT_FOUND errors when attempting to use these models:

error: "Publisher Model projects/colmobeat-content-factory/locations/us-central1/publishers/google/models/gemini-3-flash-preview was not found or your project does not have access to it"

Technical Setup:

  • Using Vertex AI SDK (google-cloud-aiplatform) with service account authentication

Thank you for considering this request. I look forward to enabling these preview capabilities for production use.
