Operation now allowed when trying to purchase Provision Throughput in Bedrock

I apologize for the difficulty you're experiencing with purchasing Provisioned Throughput in Amazon Bedrock. Based on the information you've provided, it seems you've taken several correct steps, but there might be a few additional things to check:

1. IAM Permissions: While you've granted the AmazonBedrockFullAccess policy, which is a good start, you may need to ensure that your IAM role has specific permissions for Provisioned Throughput API actions. These include actions like bedrock:CreateProvisionedModelThroughput, bedrock:GetProvisionedModelThroughput, and others related to managing Provisioned Throughput.

2. Model Access: Ensure that you have explicitly requested and been granted access to the specific model for which you're trying to purchase Provisioned Throughput. This is a prerequisite step before you can purchase Provisioned Throughput for any model.

3. Model Units (MUs): By default, an account comes with 2 Model Units to distribute between Provisioned Throughputs with no commitment. If you're trying to purchase more than this, you may need to first visit the AWS support center to request an increase in the number of MUs you can purchase.

4. Region and Model Compatibility: Double-check that the specific model variant you're trying to use supports Provisioned Throughput in your chosen region. Some models may have restrictions or may only be available in certain regions.

5. Custom Models: If you're attempting to purchase Provisioned Throughput for a custom model, ensure it's derived from a base model that supports this feature.

6. AWS GovCloud Restrictions: If you're in the AWS GovCloud (US) Region, note that you can only purchase Provisioned Throughput for custom models with no commitment.

If you've verified all these points and are still encountering the "Operation not allowed" error, I recommend contacting AWS Support for further assistance. They can provide more specific guidance based on your account details and the exact model you're trying to use.

Hello.

It's possible that your AWS account has restrictions on using Bedrock.
In this case, I recommend that you open a case with AWS Support under "Account and billing" since there may not be anything you can do to resolve the issue.
