Creates a new custom model in Amazon Bedrock. After the model is active, you can use it for inference.

You can provide the model data source in one of the following ways:

  • customModelDataSource — Specify a SageMaker AI model package ARN. Amazon Bedrock resolves the model package to retrieve the model artifacts. This is the preferred method for new SageMaker AI training outputs.

  • modelSourceConfig — Specify an Amazon S3 URI pointing to the Amazon-managed Amazon S3 bucket containing your model artifacts.

To use the model for inference, you must purchase Provisioned Throughput for it. You can't use On-demand inference with these custom models. For more information about Provisioned Throughput, see Provisioned Throughput.

The model appears in ListCustomModels with a customizationType of imported. To track the status of the new model, you use the GetCustomModel API operation. The model can be in the following states:

  • Creating - Initial state during validation and registration

  • Active - Model is ready for use in inference

  • Failed - Creation process encountered an error

Request body

modelNamestring required

A unique name for the custom model.

modelKmsKeyArnstring
<p>The Amazon Resource Name (ARN) of the customer managed KMS key to encrypt the custom model. If you don't provide a KMS key, Amazon Bedrock uses an Amazon Web Services-managed KMS key to encrypt the model. </p> <p>If you provide a customer managed KMS key, your Amazon Bedrock service role must have permissions to use it. For more information see <a href="https://docs.aws.amazon.com/bedrock/latest/userguide/encryption-import-model.html">Encryption of imported models</a>. </p>
roleArnstring
<p>The Amazon Resource Name (ARN) of an IAM service role that Amazon Bedrock assumes to perform tasks on your behalf. This role must have permissions to access the Amazon S3 bucket containing your model artifacts and the KMS key (if specified). For more information, see <a href="https://docs.aws.amazon.com/bedrock/latest/userguide/model-import-iam-role.html">Setting up an IAM service role for importing models</a> in the Amazon Bedrock User Guide.</p> <p>This field is required when you use <code>modelSourceConfig</code> with an Amazon S3 data source. It is not required when you use <code>customModelDataSource</code> with a model package ARN, because Amazon Bedrock uses its own credentials to access the model artifacts.</p>
clientRequestTokenstring

A unique, case-sensitive identifier to ensure that the API request completes no more than one time. If this token matches a previous request, Amazon Bedrock ignores the request, but does not return an error. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/APIReference/Run_Instance_Idempotency.html">Ensuring idempotency</a>.
