{% hint style="info" %}
**Note**: `Name`, `uri`, and `version` must be unique. If these values already exist in the model catalog and the model is in use, consider deleting the model everywhere it is currently running before continuing with this demonstration, or use your own values.
{% endhint %}

4. In the wizard which appears, enter the following details:

{% tabs %}
{% tab title="Seldon Core 2" %}

| Name         | `cifar10`            |
| ------------ | -------------------- |
| Namespace    | `seldon`             |
| Type         | `Seldon ML Pipeline` |
| Runtime      | `Tensorflow`         |
| {% endtab %} |                      |

{% tab title="Seldon Core 1" %}

| Name       | `cifar10`                                      |
| ---------- | ---------------------------------------------- |
| Namespace  | `seldon`                                       |
| Type       | `Seldon Deployment`                            |
| Runtime    | `Triton (ONNX, PyTorch, Tensorflow, TensorRT)` |
| Model Name | `cifar10`                                      |

{% hint style="warning" %}
The `Model Name` is linked to the name described in the `model-settings.json` file, located in the Google Cloud Storage location. Changing the name in the JSON file would also require changing the `Model Name`, and vice versa.
{% endhint %}

{% endtab %}
{% endtabs %}

5. Click `Next` steps, then click `Launch`.

Select the `Overview` header tab to verify that your model has been deployed.

## Edit Model Metadata

{% hint style="info" %}
**Note**:

* Changing the prediction schema will require a new model to be registered.
* You can click on the vertical ellipses `⋮` button to clone a model and set a new prediction schema with a different `version`.
* `Name`, `Version`, `Tags`, and `Metrics` can be changed at any time.
  {% endhint %}
