Export AutoML tabular models

This page describes how to use Vertex AI to export your AutoML tabular model to Cloud Storage, download the model to an on-premises server or a server hosted by another cloud provider, and then use Docker to make the model available for predictions.

For information about exporting image and video Edge models, see Export AutoML Edge models.

After exporting your tabular model, if you want to import it back into Vertex AI, see Import models to Vertex AI.


Exporting AutoML tabular models has the following limitations:

  • You can export AutoML tabular classification and regression models only. Exporting AutoML tabular forecasting models is not supported.

  • Vertex Explainable AI is not available using exported tabular models. If you need to use Vertex Explainable AI, you must serve predictions from a model hosted by Vertex AI.

  • The exported tabular model can run only on x86 architecture CPUs that support Advanced Vector Extensions (AVX) instruction sets.

Export process

The steps for exporting your model are:

  1. Set up your environment.
  2. Export the model.
  3. Run the model server.
  4. Request predictions.

Before you begin

Before you can complete this task, you must have completed the following tasks:

  • Set up your project as described in Setting up the cloud environment.
  • Train the model that you want to download.
  • Install and initialize the Cloud SDK on the server you will use to run the exported model.
  • Install Docker on your server.
  • Pull the Vertex AI model server Docker image:

    sudo docker pull MULTI_REGION-docker.pkg.dev/vertex-ai/automl-tabular/prediction-server-v1

    Replace MULTI_REGION with us, europe, or asia to select which Docker repository you want to pull the Docker image from. Each repository provides the same Docker image, but choosing the Artifact Registry multi-region closest to the machine where you are running Docker might reduce latency.

Export the model


  1. In the Cloud Console, in the Vertex AI section, go to the Models page.

    Go to the Models page

  2. Click the tabular model you want to export to open its details page.

  3. Click Export in the button bar to export your model.

  4. Select or create a Cloud Storage folder in the desired location.

    The bucket must meet the bucket requirements.

    You cannot export a model to a top-level bucket. You must use at least one level of folder.

    For best results, create a new, empty folder. You will copy the entire contents of the folder in a later step.

  5. Click Export.

    You will download the exported model to your server in the next section.


You use the models.export method to export a model to Cloud Storage.

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

  • LOCATION: Your region.
  • PROJECT: Your project ID or project number.
  • MODEL_ID: the ID of the model you want to export.
  • GCS_DESTINATION : your destination folder in Cloud Storage. For example, gs://export-bucket/exports.

    You cannot export a model to a top-level bucket. You must use at least one level of folder.

    The folder must conform to the bucket requirements.

    For best results, create a new folder. You will copy the entire contents of the folder in a later step.

HTTP method and URL:

POST https://LOCATION-aiplatform-googleapis.com/v1/projects/PROJECT/locations/LOCATION/models/MODEL_ID:export

Get the status of an export operation

Some requests start long-running operations that require time to complete. These requests return an operation name, which you can use to view the operation's status or cancel the operation. Vertex AI provides helper methods to make calls against long-running operations. For more information, see Working with long-running operations.

Run the model server

In this task, you will download your exported model from Cloud Storage and start the Docker container, so your model is ready to receive prediction requests.

Your model must be run inside a Docker container.

To run the model server:

  1. On the machine where you will run the model, change to the directory where you want to save the exported model.

  2. Download the exported model:

    gsutil cp -r <var>gcs-destination</var> .

    Where gcs-destination is the path to the location of the exported model in Cloud Storage.

    The model is copied to your current directory, under the following path:


  3. Rename the directory so the timestamp is removed.

    mv model-<model-id>/tf-saved-model/<export-timestamp> model-<model-id>/tf-saved-model/<new-dir-name>

    The timestamp makes the directory invalid for Docker.

  4. Start the Docker container, using the directory name you just created:

    docker run -v `pwd`/model-<model-id>/tf-saved-model/<new-dir-name>:/models/default -p 8080:8080 -it MULTI_REGION-docker.pkg.dev/vertex-ai/automl-tabular/prediction-server-v1

    Replace MULTI_REGION with the same value that you used in the Before you begin section of this guide (us, europe, or asia), so that the Docker image URI matches the URI of the Docker image that you pulled previously.

You can stop the model server at any time by using Ctrl-C.

Update the model server docker container

Because you download the model server Docker container when you export the model, you must explicitly update the model server to get updates and bug fixes. You should update the model server periodically, using the following command:

docker pull MULTI_REGION-docker.pkg.dev/vertex-ai/automl-tabular/prediction-server-v1

Replace MULTI_REGION with the same value that you used in the Before you begin section of this guide (us, europe, or asia), so that the Docker image URI matches the URI of the Docker image that you pulled previously.

Get predictions from the exported model

The model server in the Vertex AI image container handles prediction requests and returns prediction results.

Batch prediction is not available for exported models.

Prediction data format

You provide the data (payload field) for your prediction request the following JSON format:

{ "instances": [ { "column_name_1": value, "column_name_2": value, … } , … ] }

The following example shows a request with three columns: a categorical column, a numeric array, and a struct. The request includes two rows.

  "instances": [
      "categorical_col": "mouse",
      "num_array_col": [
      "struct_col": {
        "foo": "piano",
        "bar": "2019-05-17T23:56:09.05Z"
      "categorical_col": "dog",
      "num_array_col": [
      "struct_col": {
        "foo": "guitar",
        "bar": "2019-06-17T23:56:09.05Z"

Make the prediction request

  1. Put your request data into a text file, for example, tmp/request.json.

    The number of rows of data in the prediction request, called the mini-batch size, affects the prediction latency and throughput. The larger the mini- batch size, the higher the latency and throughput. For reduced latency, use a smaller mini-batch size. For increased throughput, increase the mini-batch size. The most commonly used mini-batch sizes are 1, 32, 64, 128, 256, 512, and 1024.

  2. Request the prediction:

    curl -X POST --data @/tmp/request.json http://localhost:8080/predict

Prediction results format

The format of your results depends on your model objective.

Classification model results

Prediction results for classification models (binary and multi-class) return a probability score for each potential value of the target column. You must determine how you want to use the scores. For example, to get a binary classification from the provided scores, you would identify a threshold value. If there are two classes, "A" and "B", you should classify the example as "A" if the score for "A" is greater than the chosen threshold, and "B" otherwise. For imbalanced datasets, the threshold might approach 100% or 0%.

The results payload for a classification model look similar to this example:

  "predictions": [
      "scores": [
      "classes": [
      "scores": [
      "classes": [

Regression model results

A predicted value is returned for each valid row of the prediction request. Prediction intervals are not returned for exported models.

The results payload for a regression model look similar to this example:

  "predictions": [
      "value": -304.3663330078125,
      "lower_bound": -56.32196807861328,
      "upper_bound": 126.51904296875
      "value": -112.3663330078125,
      "lower_bound": 16.32196807861328,
      "upper_bound": 255.51904296875
