Bedrock and a hard place: Claude adventure leaves AWS user staring down $30K invoice

An AWS user incurred a $30,141.33 invoice after using Anthropic's Claude Opus on Amazon Bedrock, despite using AWS Cost Anomaly Detection to avoid surprises. The issue arose because AWS Marketplace charges are not supported by Cost Anomaly Detection. The user's AWS Activate credits masked the initial costs, leading to an unexpectedly large invoice.
