Track Amazon Bedrock Costs by Caller Identity with IAM Principal-Based Cost Allocation

This article announces IAM Principal-Based Cost Allocation for Amazon Bedrock, enabling organizations to track Bedrock costs by caller identity automatically.

• Automatically records IAM user/role identity for every Bedrock API call in CUR 2.0 and Cost Explorer
• Eliminates manual CloudTrail log reconciliation for cost attribution
• Enables cost allocation by department, team, project, or custom organizational structures
• Setup requires: tagging IAM principals, activating tags in Billing console, enabling IAM principal data in CUR 2.0
• Session tags support dynamic cost attribution through gateway architectures
• No additional charge; CUR file sizes increase due to expanded line items per principal
• Data appears in reports within 24 hours of activation

Organizations can now gain granular visibility into Bedrock spending by IAM principal without custom tooling, enabling accurate chargeback and cost optimization.
