Cost Attribution and Control for AI Developer and Productivity Tools on Amazon Bedrock

Amazon Bedrock now provides zero-instrumentation cost attribution that traces every inference call back to the IAM principal that made it, with identity and organizational tags flowing into CUR 2.0 and Cost Explorer. The mechanism works at the endpoint layer, so Claude Code, Claude Desktop, OpenAI Codex, ChatGPT Work, and OpenCode all inherit per-user cost visibility once identity propagation is configured. The post walks through setting up IAM Identity Center with an external IdP, session tags for team and cost center, Athena queries, and Bedrock-native usage controls to enforce spending limits.
