Vertex AI PublisherModel API does not expose Model Garden model card metadata (display name, overview, tags)

Google Cloud Build with AI Generative AI & Foundational Models
1

ertex AI Model Garden UI displays rich model card information for publisher models (e.g. Google, Anthropic, OpenAI), including:

Display name

Overview / description

Tags (such as Text, Chat, Multimodal, etc.)

However, when using the public Vertex AI PublisherModel API (publishers.models.get / list via REST or PublisherModelServiceClient in Python), these fields are not present. The API response appears limited to structural and capability metadata such as:

name

open_source_category

supported_actions

frameworks

launch_stage / version_state

We have verified this behavior using both v1 and v1beta1 APIs and the google-cloud-aiplatform Python client.

Questions / clarification requested:

Is the Model Garden card metadata (display name, overview, tags) intentionally UI-only and not exposed via any public API?

Is there an alternative supported API or resource to programmatically retrieve this metadata?

Are there plans to expose this information through the PublisherModel API or a related endpoint?

This information is needed to programmatically inventory and classify Model Garden models without relying on the UI.

Hi @ilnardo92 , @Surendra_Galwa
any progress on this,
I have also tried multiple times with different options, no luck,
actually, I was checking about listing the vertex AI search app → models.
from discovery service
finding or searching the widgetConfig only is the big thing, then it gives only the model name as
gemini-2.5-flash/answer_gen/v1, tried like getting with servingConfig, no luck, then tried to get the metadata for the base model, gemini-2.5-flash, no luck.

then from aiplatformservice. used Rest API, publisher.model.get, It gives only the references like,

{

“name”: “publishers/google/models/gemini-2.5-flash”,

“versionId”: “default”,

“supportedActions”: {

"openGenerationAiStudio": {

  "references": {

    "us-central1": {

      "uri": " https://console.cloud.google.com/vertex-ai/generative/multimodal/create/text?model=gemini-2.5-flash "

    }

  }

}

},

“launchStage”: “GA”,

“publisherModelTemplate”: “projects/{project}/locations/{location}/publishers/google/models/gemini-2.5-flash@default”

}
tried here with publishermodeltemplate, but, it won’t give the model card, found this thread discussed about the same 3 months ago, can you pls help here.
similarly, I also tried v1/v1beta1/ & rest & also python. thought to escalate this.
appreciate your response.
thanks.
