# Request a Quota Increase
<a name="canvas-requesting-quota-increases"></a>

Your users might use AWS resources in amounts that exceed those specified by their quotas. If your users are resource constrained and encounter errors in SageMaker Canvas, you can request a quota increase for them.

For more details about SageMaker AI quotas and how to request a quota increase, see [Quotas](https://docs.aws.amazon.com/sagemaker/latest/dg/regions-quotas.html#regions-quotas-quotas).

Amazon SageMaker Canvas uses the following services to process the requests of your users:
+ Amazon SageMaker Autopilot
+ Amazon SageMaker Studio Classic domain

For a list of the available quotas for SageMaker Canvas operations, see [Amazon SageMaker AI endpoints and quotas](https://docs.aws.amazon.com//general/latest/gr/sagemaker.html).

## Request an increase for instances to build custom models
<a name="canvas-requesting-quota-increases-instances"></a>

When building a custom model, if you encounter an error during post-building analysis that tells you to increase your quota for `ml.m5.2xlarge` instances, use the following information to resolve the issue.

You must increase the SageMaker AI Hosting endpoint quota for the `ml.m5.2xlarge` instance type to a non-zero value in your AWS account. After building a model, SageMaker Canvas hosts the model on a SageMaker AI Hosting endpoint and uses the endpoint to generate the post-building analysis. If you don't increase the default account quota of 0 for `ml.m5.2xlarge` instances, SageMaker Canvas cannot complete this step and generates an error during post-building analysis.

For the procedure to increase the quota, see [ Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*.
