+## Manage Model Cards
 
-All of the Model cards in model store are managed by project admin.
-After uploading model store with model-definition file, any user in the project
-can access to model card and clone it if needed.
+Model cards in the Model Store are created and managed through the [Admin Model Store Management](#admin-model-store-management) interface. Each model card is linked to a storage folder (vfolder) that contains the actual model files.
 
-Following method is to add model cards from the Hugging Face.
+### Setting Up the Model Store Folder
 
 :::note
-Before creating a model card, getting an access to the specific model on Hugging Face is needed.
-For more information, please refer to [Gated models](https://huggingface.co/docs/hub/models-gated) .
+If the model is hosted on Hugging Face as a gated model, you will need to request access before downloading. Refer to [Gated models](https://huggingface.co/docs/hub/models-gated) for details.

-Move to data page and click the 'Create Folder' button on the right side. Enter the folder name,
-and set the rest of folder configuration as shown below:
+Go to the Data page and click the **Create Folder** button. Configure the folder as follows:
 
-- Usage Mode: Model
-- Type: project
-- Permission: Read-Write
-- Cloneable: True
+- **Usage Mode**: Model
+- **Type**: Project
+- **Permission**: Read-Write

-After creating the folder, you need to set and upload the model-definition.yaml file
-to the folder that you've just created. Following is the example of the model-definition file.
-If you want to know how to write model-definition file,
-please refer to [Model definition guide](#model-definition-guide) section.
+After creating the folder, download the model files into it. You can mount the model folder during session creation and use tools such as `huggingface-cli` to download model weights.
+
+:::note
+You need to download the model files manually into the folder. For instructions on how to download from Hugging Face, refer to [Downloading models](https://huggingface.co/docs/hub/models-downloading).
+:::
+
+Once the folder and its model files are ready, create a model card through the [Admin Model Store Management](#admin-model-store-management) interface and link it to this folder.
+

+
+### Model Definition File (Advanced — Custom Runtime)
+
+For the `Custom` runtime variant, you can optionally place a `model-definition.yaml` file in the model folder. This file tells Backend.AI how to start and operate the inference server during serving — including the startup command, health check settings, and any pre-start actions such as downloading model weights at launch time.
+
+:::note
+Runtime variants such as `vLLM`, `SGLang`, `NVIDIA NIM`, and `Modular MAX` do not require a `model-definition.yaml` file. These variants handle model configuration automatically based on the selected settings.

-you can mount the model folder to session creation and download file to there by referring
-[Downloading models](https://huggingface.co/docs/hub/models-downloading) .
+To enable the **Deploy** button on a model card in the Model Store, include `service-definition.toml` in the linked folder so Backend.AI can read the model service configuration. Add `model-definition.yaml` only when you use the `Custom` runtime variant; preset runtime variants (such as `vLLM`, `SGLang`, `NVIDIA NIM`, and `Modular MAX`) do not require it. For details on the service definition file, refer to the [Service Definition File](../model_serving/model_serving.md#service-definition-file) section in the Model Serving documentation.

+<a id="admin-serving-page"></a>
 
-The Model Store page is where users can discover and use pre-configured models that have been set up by administrators. When you navigate to the Model Store page from the sidebar, you will see model cards displaying all available models from the model-store project.
+### Admin Serving Page
 
-![](../images/model_store_page_overview.png)
+Administrators and superadmins can access the Admin Serving page, which provides a cross-project view of all endpoints. This page shows the **Project** column in addition to the standard endpoint list columns, allowing admins to manage services across all projects.
 
-Each model card displays key information about the model, including:
+![](../images/admin_serving_page.png)
 
-- Model name (folder name)
-- README content (if a README file exists in the folder)
-- Metadata from the model-definition.yaml file
-- Action buttons for interacting with the model
+The Admin Serving page has two tabs:
 
-Clicking on a model card opens a detailed view with the full README content and available actions.
+- **Serving**: Displays the endpoint list across all projects, with the same lifecycle and property filters as the user-facing Serving page.
+- **Model Store Management**: Available to superadmins only. See the section below.

-### Clone to Folder
+Superadmins can manage model cards through the **Model Store Management** tab on the Admin Serving page.
 
-The "Clone to folder" button allows you to create a personal copy of a model store folder. Since model store folders are read-only and shared across the project, you need to clone them to your own storage to modify files or use them in custom workflows.
+![](../images/admin_model_card_list_v2.png)
 
-To clone a model folder:
+The list provides the following columns:
 
-1. Click the "Clone to folder" button on the model card
-2. In the clone dialog, configure the following settings:
-   - **Folder Name**: The name for your cloned folder (defaults to the original name with a random suffix)
-   - **Permission**: Set the access permission for the cloned folder (Read-Only or Read-Write)
-   - **Usage Mode**: The folder type (General, Model, or Auto Mount)
-3. Click the "Clone" button to start the cloning process
+- **Name**: The unique identifier of the model card.
+- **Title**: The human-readable display name.
+- **Category**: The model category (e.g., LLM).
+- **Task**: The inference task type (e.g., text-generation).
+- **Access Level**: Shows a green `Public` tag when the model card is publicly accessible, or a default `Private` tag otherwise.
+- **Domain**: The domain that owns the model card.
+- **Project**: The project that owns the model card.
+- **Created At**: The timestamp when the model card was created.

+To delete multiple model cards at once, select the rows you want to remove using the checkboxes and click the red trash-bin button next to the selection count. A confirmation dialog appears before the cards are deleted.

+Click the `Create Model Card` button to open the creation modal. Fill in the following fields:
 
-### Create Service from This Model
-
-The "Run this model" button allows you to create a model service directly from a model card with a single click. This feature automates the process of cloning the model folder and creating a model service endpoint.
-
-:::note
-This button requires the following conditions to be met:
-
-- Both `model-definition.yaml` and `service-definition.toml` files must exist in the model folder. If either file is missing, the button will be disabled with a tooltip explaining which file is needed.
-- You must have sufficient resource quota to create a model service.
-- The resource group must allow inference session types.

-#### Service Creation Workflow
-
-When you click the "Run this model" button, Backend.AI follows this workflow:
-
-1. **Check for Required Files**: The system verifies that both model-definition.yaml and service-definition.toml exist in the folder
-
-2. **Clone Folder (if needed)**: If you don't have a cloned copy of the model folder:
-   - A confirmation dialog appears asking if you want to clone the folder
-   - The folder will be cloned with a name format: `{original-name}-{random-4-chars}`
-   - A notification shows the cloning progress
-
-![](../images/model_service_clone_confirmation.png)
-
-<!-- TODO: Capture screenshot of clone confirmation dialog before service creation -->
-
-3. **Create Service**: Once the folder exists (either from a previous clone or just cloned):
-   - The service is automatically created using settings from service-definition.toml
-   - A notification displays the service creation progress
-   - You can click the notification to navigate to the Model Serving page
-
-![](../images/model_service_creation_progress.png)
-
-<!-- TODO: Capture screenshot of service creation progress notification -->

-4. **View Service Details**: After creation completes, you can navigate to the Model Serving page to view the endpoint details, monitor service health, and manage the service
-

-:::note
-If a cloned folder already exists from a previous operation, the system will
-automatically use that folder to create the service. In a future release, you will
-be able to select which cloned folder to use if multiple copies exist.
