A software development company experienced an unexpected surge in LLM costs, amounting to approximately $9,100 over six days, due to a single tenant's integration error. The issue stemmed from a refactored feature that incorrectly placed an LLM summarization call within a polling loop, increasing daily calls from 2,000 to 140,000. This significant cost overrun went unnoticed because the company's monitoring dashboards aggregated data, masking the anomaly within the normal noise band of overall platform spend. The fix involved implementing per-tenant and per-feature cost attribution and setting up alerts for spend rate anomalies specific to each tenant's baseline. AI
