# AWS::SageMaker::ModelPackage InferenceSpecification
<a name="aws-properties-sagemaker-modelpackage-inferencespecification"></a>

Defines how to perform inference generation after a training job is run.

## Syntax
<a name="aws-properties-sagemaker-modelpackage-inferencespecification-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
