Provisioned Throughput pricing
An application developer, buys one model unit of Anthropic Claude Instant with 1-month commitment for their text summarization use case.
Total monthly cost incurred is 1 model unit * $39.60 * 24 hours * 31 days = $29,462.40

Thanks @sam-cox-tracebit, added.

I've got one sneaky b*****d to be added to the list:
Amazon Pinpoint-Deliverability dashboard
https://aws.amazon.com/pinpoint/pricing/

The Deliverability Dashboard is available for a fixed price of USD $1,250 per month. This charge includes reputation monitoring for up to five domains and 25 predictive email placement tests.

Note: If you cancel your subscription before the end of a billing period, we continue to charge you for the remaining days in the billing period. However, we don't charge you for the next billing period.

Thanks, added ses:PutDeliverabilityDashboardOption.
