Amazon Bedrock now supports request-level usage attribution on the InvokeModel and InvokeModelWithResponseStream APIs. Customers can tag individual inference calls with attributes like team, project, or environment, then analyze usage via Amazon Bedrock model invocation logs. This extends existing attribution capabilities (application inference profiles, IAM principal-based attribution, project-level tracking) to provide consistent tagging across the entire bedrock-runtime endpoint. The feature is available in all AWS commercial regions where Amazon Bedrock is supported.
