Platform For AI:Deploy a single model as an online service

Last Updated:Jun 21, 2026

Designer integrates seamlessly with Elastic Algorithm Service (EAS). After you complete your offline training, prediction, and evaluation pipelines, you can deploy a single model to EAS to create an online service. This topic describes how to deploy a model trained in Designer to EAS by using one-click deployment or manual deployment.

Prerequisites

You have trained a model and verified its accuracy. For more information, see Build and debug a model.

One-click deployment for a single model

Supported model components

The following model components support one-click deployment to EAS. Some other model components support only manual deployment. For more information, see Manual deployment for a single model.

Procedure

  1. Go to Visualized Modeling, select a workspace, navigate to the Designer page, and then open your target pipeline.

  2. Above the pipeline canvas, click Model List. The system automatically detects deployable models generated by the pipeline.

    In the Model List dialog box, select a target model, such as Logistic Regression for Binary Classification-1. You can click Register Model to add the model to AI assets for versioning, or click Deploy to EAS to create a model service.

  3. Select the target model and click Deploy to EAS to open the service creation page.

  4. Configure the parameters and deploy the model service.

    The system automatically matches the Model File and Processor Type. For more information about other parameters, see Custom deployment.

  5. Click Deploy. When the Service Status changes to Running, the deployment is complete.

Manual deployment for a single model

The following model components do not support one-click deployment. After model training is complete, you must use the Export a General-purpose Model component to assemble the model, export it to an OSS directory, and then deploy it manually.

After you export the model to an OSS bucket, you can manually deploy the model to EAS. For more information, see Custom deployment.

FAQ

When I use one-click deployment, a supported node is dimmed and cannot be selected. In the Model List dialog box, only the K-means Clustering-1 model is displayed, and the only available button is Close, without any options to register or deploy. How can I fix this?

Click the component node, select Generate PMML on the Field Settings tab on the right, and then rerun the node.
