AWS Cost Anomaly Detection now monitors spend on third-party foundation models running on Amazon Bedrock, such as Anthropic Claude and other provider-hosted models. Cost Anomaly Detection uses machine learning to detect and alert on unusual spend, and this launch extends that coverage to third-party model usage on Amazon Bedrock. Teams running production generative AI workloads now get automatic anomaly detection on their Amazon Bedrock model spend alongside the rest of their AWS costs.
