Need increase in quota

To request a quota increase for SageMaker instance types like ml.m5.12xlarge, you'll need to follow these steps:

1. Sign in to the AWS Management Console
2. Open the Service Quotas console
3. In the navigation pane under "Manage quotas," search for "Amazon SageMaker"
4. Choose "View quotas"
5. Search for the specific instance type quota you need (ml.m5.12xlarge for notebook instances)
6. Select the quota and choose "Request increase at account-level"
7. Enter your required quota value (at minimum 1)
8. Submit your request

You can follow the same process for your alternative options (ml.c5.9xlarge, ml.m5.24xlarge, and ml.c4.8xlarge).

If the Service Quotas console doesn't provide the option you need, you can request the increase through AWS Support:

1. Open the AWS Support Center console
2. Create a new case
3. Select "Service limit increase"
4. Search for "SageMaker" in the Limit type panel
5. Choose your region and resource type (Notebook instance)
6. Specify the instance type (e.g., "ml.m5.12xlarge") and new limit value
7. Provide a brief description explaining your use case
8. Select your preferred contact options
9. Submit the request

After submitting, you can check the status of your request in the "Quota request history" section. Some requests may be approved automatically, while others might require manual review by AWS Support, which can take from a few hours to a few days.
