How to Govern LLM Production Costs

The author asks how teams should govern API costs once LLM features transition from MVP to real production traffic.
They point out that frontier model calls, which seem manageable during prototyping, often balloon into multiple chained calls in production. Many of these are just repetitive extraction, classification, normalization, JSON formatting, entity matching, summarization, and routing. The author argues that LLMs are frequently being treated as expensive ETL / NLP / ML infrastructure in these scenarios.
They are looking for industry best practices to:
- Track costs by endpoint, workflow, user action, or prompt family
- Determine which steps should be replaced by rules, caching, smaller models, structured parsing, SQL, or traditional data pipelines
- Control expenses using gateways, observability, evals, budget limits, caching, and model routing
- Incrementally engineer "prompt logic" without disrupting production behavior
