Amazon's playbook shows FinOps and platform teams how to attribute, observe, enforce, optimize and review Amazon Bedrock generative AI spend as a five-stage loop. It argues that comparing per-model token rates and shortening prompts does not answer which team spent what on which workload, or whether that spend stayed inside an approved budget. Agentic workflows issue many invocations per task and carry larger context, so token consumption scales with the autonomy granted and the context carried rather than with user interactions, the post says. Amazon Bedrock automatically attributes inference costs to the IAM principal that made the call across all models, with the caller's ARN landing in the line_item_iam_principal column of the AWS Cost and Usage Report 2.0. Coverage spans IAM users, roles, federated identities and API keys, and activated tags appear in AWS Cost Explorer under the IAM category within 24–48 hours. The post warns that an LLM gateway calling Bedrock through a single IAM role attributes every dollar to that one role, and recommends assuming the invocation role once per user with session names and tags, caching credentials for up to an hour.

## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/managing-amazon-bedrock-costs-end-to-end-a-playbook-for-finops-and-platform-teams/:

> Cost management for generative AI is a shared responsibility between the teams that build applications and the teams accountable for cloud spend. Many teams start by comparing per-model token rates and asking application teams to shorten prompts. Those steps help, but they don’t answer the questions that finance and engineering leaders ask as usage scales: which team spent this, on which workload, and was that spend inside an approved budget?
> 
> Agentic workloads make those questions more pressing. A conversational assistant typically issues one model invocation per user turn. An agentic workflow, such as an AI coding assistant that plans a change, reads files, calls tools, and iterates, issues many invocations per task and carries a larger context on each one. Token consumption therefore scales with the degree of autonomy you grant the workflow and the size of the context it carries, rather than with the number of user interactions. Because consumption is a function of how a workload is designed and operated, cost management for generative AI is an architectural and operational discipline.
