The new AI-powered feature uses Amazon Q to provide plain-language explanations of detected cost anomalies by analyzing cost data alongside AWS CloudTrail events. It identifies whether cost changes arise from usage or rate variations and attributes them to services, accounts, or API calls.

For customers with organization-wide CloudTrail trails, automatic multi-account investigations simplify anomaly resolution. Users can continue querying the AI to explore deeper details. This capability is available across commercial AWS Regions at no extra charge, although related CloudWatch Logs Insights queries may incur standard fees.
