Known limitations

This document describes the known issues and limitations for Gemini Enterprise.

Connecting and managing data

The following are known issues and limitations when connecting and managing your data in Gemini Enterprise:

  • You can only have 500 data stores per project. If you need more data stores, you need to use a new project.

  • You can only have 500 Gemini Enterprise apps per project. If you need more apps, you need to use a new project.

  • After you create an app, the Google Cloud project and location are fixed for the data store and app. Data and settings cannot be automatically migrated between different projects or locations.

  • You cannot connect your website data to a Gemini Enterprise app.

  • An app can only support one data connection method (federated or ingestion) for a connector. If the connector supports both data federation and data ingestion, select your preferred data connection method.

Using Gemini 3.1 Pro in Limited Availability

Gemini Enterprise users now have access to 3.1 Pro in Limited Availability as a Pre-GA Offering but with soon-to-be announced General Availability SLOs. The goal is to enable our users to use these 3 series models in their production workloads.

The following are specific constraints and known limitations for the deployment of select Gemini 3 models within Gemini Enterprise in Limited Availability. For information about regional availability and data residency commitments, see Gemini Enterprise Standard and Plus Editions data residency and ML regional processing commitments.

Deployment status

  • Limited Availability: The Gemini 3 series models are currently offered as a Pre-GA Offering - Limited Availability status within Gemini Enterprise. "Limited Availability" as used here means that while this model deployment will provide, in time, production-grade General Availability (GA) SLOs, as a Pre-GA Offering we don't provide full GA contractual commitments such as lifetime support or standardized 12-month deprecation notice for changes to the model or its availability.
  • Cloud Data Processing Addendum: As a Pre-GA Offering with Limited Availability status, you may use Gemini 3.1 Pro as of the last updated date in Gemini Enterprise to process personal data as outlined in the Cloud Data Processing Addendum.

Access limitations

  • No Direct API Access: The specific Limited Availability model capabilities are available exclusively through the Gemini interface and integrated surfaces. For this specific deployment, you won't have access to these models using the Vertex AI API.
