This article outlines six common patterns that lead to unexpected cost explosions in LLM operations, particularly for marketing automation. It emphasizes that unlike traditional SaaS, LLM costs are not directly proportional to user growth and can surge due to factors like longer responses, excessive retries, accumulating context, model upgrades, and complex tool usage. The author proposes specific "guardrails" for each pattern, including implementing exponential backoff for retries, managing prompts via Git with length monitoring, enforcing explicit context window truncation, pinning model versions instead of using aliases, setting maximum iterations for agent loops, and monitoring prompt cache hit rates. The piece concludes by recommending a monitoring dashboard with key metrics to proactively detect cost anomalies. AI
