Gemini API models (gemini-pro, gemini-pro-vision) not found on a new, fully configured project

Google Cloud Build with AI Generative AI & Foundational Models
1

Hello,

I have a persistent issue with activating the Gemini API on a new Google Cloud project. Despite following all the setup steps correctly, I’m unable to access any Gemini models.

What I have done:

  1. Created a brand new Google Cloud project (PII Removed by Staff).

  2. Generated a new, unrestricted API key for this project.

  3. Successfully enabled the “Generative Language API” in the API library. The console shows it as “Enabled”.

  4. Successfully linked a valid and active billing account to the project.

The Problem: No matter which model I try to call (gemini-pro or gemini-pro-vision), I consistently receive the following error: "models/gemini-pro is not found for API version v1beta, or is not supported for generateContent."

This happens for both text-only and vision models, which suggests the models have not been activated for my account/project in my region, even though the API is enabled and billing is active.

I cannot open a technical support case because I am on the standard support plan.

Could someone from Google please check the provisioning status of the Generative AI models for my project? It seems to be an account-level activation delay.

Thank you.
