Hi Google AI Team,

Requesting allowlist access for the following GA image generation  
models on Vertex AI / Agent Platform:

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

Project details:

- GCP Project ID: gen-lang-client-0427050142
- Project Display Name: FPA api key
- Region: us-central1
- Endpoint: global
- Billing: Enabled and active (monthly spend approximately $50)
- Agent Platform API ([aiplatform.googleapis.com](http://aiplatform.googleapis.com)): Enabled
- Service Account: [ai-studio-max-vertex@gen-lang-client-0427050142.iam.gserviceaccount.com](mailto:ai-studio-max-vertex@gen-lang-client-0427050142.iam.gserviceaccount.com)
- Service account roles: Agent Platform User (roles/aiplatform.user) +  
Service Usage Consumer
- Auth method: Service account JSON key

Use case:  
Native 3ds Max plugin (AI Studio Max) for architectural visualization  
workflows. The plugin integrates frontier image generation and editing  
models directly inside Autodesk 3ds Max, capturing viewport with  
camera context (FOV, focal length, pitch) and producing contextualized  
architectural renders for production use. Currently in development  
with a small group of professional CG artist testers in architectural  
visualization.

Currently running on the Gemini consumer API but moving to Vertex AI  
for production stability. We’ve experienced significant disruption  
during the recurring “high demand” 503 outages over the past three  
weeks on the consumer endpoints (May 29 - June 10), losing multiple  
production days. The deprecation of the preview endpoints on June 25  
adds further pressure to migrate to a stable enterprise path.

End-to-end integration is verified on gemini-2.5-flash-image. Ready  
to upgrade to the 3.x models as soon as access is granted — all  
infrastructure (service account, IAM, API enablement, billing) is  
provisioned.

Thanks for considering!
