How do you design cost explosion prevention systems in LLMOps?

Cost explosion prevention uses token budgeting, request throttling, anomaly detection, and adaptive routing to control LLM spend.

LLM systems can experience uncontrolled cost spikes due to long prompts, loops, or traffic surges. Prevention mechanisms include per-user and per-service token budgets, real-time cost anomaly detection, prompt truncation, dynamic model downgrading, and circuit breakers that disable expensive paths when thresholds are exceeded.
