Request allowlist access for Gemini 3 Preview - Vertex AI

Hello Google AI Team,

I would like to request allowlist access for my Vertex AI project to use Gemini 3 Flash Preview.

Model needed:

  • gemini-3-flash-preview
  • gemini-3-pro-preview

Project Information:

  • Location: global

I am currently receiving this error:
“Publisher Model gemini-3-flash-preview was not found or your project does not have access to it.”

Thank you in advance!
