AWS user hit with 30000 dollar bill after Claude runaway on Bedrock

An AWS user just stared down a $30,000 invoice after a Claude adventure on Bedrock with no guardrails catching it. Cost Anomaly Detection failed entirely, which matters because this is the exact tooling AWS markets as the safety net for runaway spend. Anthropic is now metering and throttling programmatic Claude usage at the API layer, a supply-side response that only makes sense if inference costs are genuinely outpacing what the pricing model can absorb.
