Vertex AI Search App Governance

Google Cloud Build with AI Conversational Agents (Dialogflow CX)
1

Hi All,

As part of the governance, I am querying list of AI applications(search apps)

We can configure, models etc to the search app.

  1. As part of the governance, I get the model used from discoveryengine api, However, I dont find the api to get the model card for the model modelVersion": “gemini-2.5-flash/answer_gen/v1” or even to the base model gemini-2.5-flash
    I have tried from discovery searchConfig/ anything of modelspec anything or
    Even tried from ai-platform, client = aiplatform_v1.ModelGardenServiceClient()
    No luck, how & from where I can get the metadata for this model. If not specific version or to the base version(gemini-2.5-flash)
    Thanks,
    Kalpa.

Hi, Kalpa @Kalpa_T .

Governance in Vertex AI Search is critical, especially when dealing with enterprise data. From my perspective as a researcher at Whitecyber Data Science Lab, app governance should not only focus on access control but also on Data Integrity.

Without a strict governance framework, search apps are prone to retrieving outdated or irrelevant information, which leads to AI Hallucinations. In our methodology, we emphasize ‘Human-in-the-loop’ validation to ensure that the search outcomes are aligned with the intended ‘sovereign’ knowledge base of the organization.

I would suggest looking into Data Store audit logs and setting up rigorous schema validation as part of your governance checklist. Looking forward to hearing more insights from others on how they manage large-scale search deployments!
