Copy a model in Vertex AI Model Registry

Training your AutoML, large models, and custom models in Vertex AI to the level you want requires time and some experimentation. If you have a well-performing model you'd like to use in another project or location, training a new model is not the best option. Model training is non-deterministic in nature therefore it's unlikely you'd end up with an identical model from identical data. Additionally, training a model in each region or project is not a foolproof way to maintain cross-region model behavior consistency. With Vertex AI Model Registry copy model, you can copy a model from the Vertex AI Model Registry into a separate location in the same project or to a different project.

When performing a model copy, if you don't specify the model version you want to copy over, the default model version is copied. To learn more about model default or the model alias, see How to use model aliases.

Limitations

When you copy a model, not all model information is copied over. The copied model won't retain the following:

Version aliases.
The custom model ID. You can specify a new ID once the model is copied.
Any existing model evaluation.
Encryption specs. You're required to specify a new one upon copy for your target region.
Deployments and batch predictions.
For cross-project copy, you can copy custom models which have a third party container image.

Copy models between projects

Prerequisites

To copy a model across projects, the source model owner needs to first grant the model export permission to the destination project:

Select your project from the Google Cloud console.
Navigate to the IAM & Admin page.
On the IAM permissions page, click Grant access and a pop up window appears to allow you add a new principal to the source project.
Get the numerical project number of the destination project, and the P4SA credential of the destination project
Add the destination project P4SA credential as the new principal to the source project and assign the Vertex AI Service Agent role to the destination project P4SA.
After clicking the Save, the destination project P4SA has permissions to export models from the source project.

REST

Before using any of the request data, make the following replacements:

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json, and execute the following command:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \

Save the request body in a file named request.json, and execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }
