Gemini batch with gemini-3-pro-preview issues

This does not work for gemini-3-pro-preview, I get the following response:

"projects/[my-billing-project]/locations/us-central1/publishers/google/models/gemini-3-pro-preview` was not found or your project does not have access to it."

I read elsewhere that preview models are only global. So I changed my endpoint and location to:

global-aiplatform.googleapis.com:443

global

This results in a 404 error:

The requested URL <code>/google.cloud.aiplatform.v1.JobService/CreateBatchPredictionJob</code> was not found on this server.

That path must be coming from the library. I am on the latest com.google.cloud:google-cloud-aiplatform:3.81.0, November 14.

I am running out of ideas. Did anyone yet use gemini-3-pro-preview in batch mode? What is the difference from the 2.5 models?
