# ListInferenceRecommendationsJobSteps


Returns a list of the subtasks for an Inference Recommender job.

The supported subtasks are benchmarks, which evaluate the performance of your model on different instance types.

## Request Syntax


```
{
   "JobName": "string",
   "MaxResults": number,
   "NextToken": "string",
   "Status": "string",
   "StepType": "string"
}
```

The name for the Inference Recommender job.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 64.  
Pattern: `[a-zA-Z0-9](-*[a-zA-Z0-9]){0,63}`   
Required: Yes

 ** [MaxResults](#API_ListInferenceRecommendationsJobSteps_RequestSyntax) **   <a name="sagemaker-ListInferenceRecommendationsJobSteps-request-MaxResults"></a>
The maximum number of results to return.  
Type: Integer

Pattern: `.*`   
Required: No

 ** [Status](#API_ListInferenceRecommendationsJobSteps_RequestSyntax) **   <a name="sagemaker-ListInferenceRecommendationsJobSteps-request-Status"></a>
A filter to return benchmarks of a specified status. If this field is left empty, then all benchmarks are returned.  
Type: String  
Valid Values: `PENDING | IN_PROGRESS | COMPLETED | FAILED | STOPPING | STOPPED | DELETING | DELETED`   
Required: No

 ** [StepType](#API_ListInferenceRecommendationsJobSteps_RequestSyntax) **   <a name="sagemaker-ListInferenceRecommendationsJobSteps-request-StepType"></a>
A filter to return details about the specified type of subtask.
