When your LLM costs are invisible to the teams making decisions, you cannot optimize. You are flying blind.
The solution is not better dashboards. It is putting cost visibility where decisions happen.
Three Patterns That Work in Production
Pattern 1: Correlation IDs
Every LLM request carries a correlation ID from entry to exit. This ID links:
- Business context (customer, feature, workflow)
- LLM call details (model, tokens, latency)
- Cost (exact cost for this request)
One UUID at the request boundary. One thread through your LLM client. Three lines of code.
Pattern 2: Selective Instrumentation
Do not meter everything. Meter the decisions.
In most systems, 20% of LLM calls drive 80% of cost. Find those 20%. Instrument only those call sites.
Pattern 3: Attribution Closing the Loop
Show each decision-maker the real cost of their decisions.
Slack summaries. Dashboard per endpoint. Teams see cost as a signal in their tradeoff decisions.
Why This Works
You are not asking teams to think about optimization. You are giving them the signal they already use: cost per decision, visible where it matters.
