It helps you safely test new models against production traffic by routing a portion of requests to each variant and collecting metrics such as accuracy, latency, and cost. This enables data-driven decisions when promoting models to production. ``` aws.sagemaker_inference_experiment ``` ## Fields | Title | ID | Type | Data Type | Description | | ------------------- | ---- | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ----------- | | _key | core | string | | account_id | core | string | | arn | core | string | The ARN of the inference experiment being described. | | completion_time | core | timestamp | The timestamp at which the inference experiment was completed. | | creation_time | core | timestamp | The timestamp at which you created the inference experiment. | | data_storage_config | core | json | The Amazon S3 location and configuration for storing inference request and response data. | | description | core | string | The description of the inference experiment. | | endpoint_metadata | core | json | The metadata of the endpoint on which the inference experiment ran. | | last_modified_time | core | timestamp | The timestamp at which you last modified the inference experiment. | | model_variants | core | json | An array of ModelVariantConfigSummary objects. There is one for each variant in the inference experiment. Each ModelVariantConfigSummary object in the array describes the infrastructure configuration for deploying the corresponding variant. | | name | core | string | The name of the inference experiment. | | role_arn | core | string | The ARN of the IAM role that Amazon SageMaker can assume to access model artifacts and container images, and manage Amazon SageMaker Inference endpoints for model deployment. | | schedule | core | json | The duration for which the inference experiment ran or will run. | | shadow_mode_config | core | json | The configuration of ShadowMode inference experiment type, which shows the production variant that takes all the inference requests, and the shadow variant to which Amazon SageMaker replicates a percentage of the inference requests. For the shadow variant it also shows the percentage of requests that Amazon SageMaker replicates. | | status | core | string | The status of the inference experiment. The following are the possible statuses for an inference experiment: Creating - Amazon SageMaker is creating your experiment. Created - Amazon SageMaker has finished the creation of your experiment and will begin the experiment at the scheduled time. Updating - When you make changes to your experiment, your experiment shows as updating. Starting - Amazon SageMaker is beginning your experiment. Running - Your experiment is in progress. Stopping - Amazon SageMaker is stopping your experiment. Completed - Your experiment has completed. Cancelled - When you conclude your experiment early using the StopInferenceExperiment API, or if any operation fails with an unexpected error, it shows as cancelled. | | status_reason | core | string | The error message or client-specified Reason from the StopInferenceExperiment API, that explains the status of the inference experiment. | | tags | core | hstore_csv | | type | core | string | The type of the inference experiment. |
