+Cost Anomaly Detection does not monitor third-party products and services available through AWS Marketplace. This includes third-party LLMs like Anthropic Claude models on Amazon Bedrock (which appear in Cost Explorer and on your bill under the legal entity "Anthropic, PBC") and any models you deploy through Amazon Bedrock Marketplace. To get alerts for these charges, use AWS Budgets. A cost budget tracks your total AWS costs, including AWS Marketplace. You can use the **Billing entity** filter to track AWS Marketplace charges specifically. For more information, see [Creating a budget](https://docs.aws.amazon.com/cost-management/latest/userguide/budgets-create.html).
