LLM cost dashboards typically report spend per model or per thousand calls, but cannot answer product owners' questions about the cost per user action. This is because a single user action can trigger multiple LLM calls, and provider degradations can increase the number of calls through retries. To address this, the author proposes propagating a unique action ID through all related LLM calls using OpenTelemetry traces. This allows for accurate cost attribution to specific user actions, providing earlier and more actionable insights into spend spikes and provider performance. AI
