+# Deploying your model on a SageMaker Endpoint with boto3
+
+As an alternate to using the SageMaker python sdk, you could also use a sagemaker client from boto3. Currently, this provides with some additional options to configure your SageMaker endpoint.
+
+## Using ProductionVariants to customize the endpoint
+The following options may be added to the `ProductionVariants` field to support LLM deployment:
+
+1. VolumeSizeInGB: option to attach a larger EBS volume if necessary.
+2. ModelDataDownloadTimeoutInSeconds: some models, due to their large size, take longer to be downloaded from S3 and untarred. With this option, you can increase the timeout for such downloads.
+3. ContainerStartupHealthCheckTimeoutInSeconds: Since LLMs may take longer to be loaded and ready to serve, the default /ping timeout of 5 minutes may not be sufficient. With this option, you can increase the timeout for the health check.

+## Using ModelDataSource to deploy uncompressed model artifacts
+The following options may be added to the `ModelDataSource` field to support uncompressed artifacts from S3:
+```

+                "CompressionType": "None",
