  "account": "Comparing the production cost per token for an in-app LLM chatbot should focus on the cost per accepted decision, rather than just the advertised cost per token. To compare models or services effectively, establish three budgets: malformed-output budget, latency budget, and spend budget. The useful unit for evaluation is an accepted score, not the individual request. This approach acknowledges that a cheaper token might result in more unusable decisions if the model produces more malformed outputs. However, this method has limitations—it cannot predict quality from token volume and cannot replace a representative evaluation corpus. The tradeoff involves balancing a small, auditable contract for safer operations against a richer contract that preserves more nuance but requires additional validation and review work. This approach is suitable for workflows with fixed fields such as score, evidence, and missing_requirements, but not for open-ended conversations where a human can accept a useful answer without such constraints.",
  "summary": "How to Compare LLM Chatbot Production Cost Per Token — With 3 Failure Budgets Short answer: for an in-app LLM chatbot, compare production cost per accepted decision, not the advertised cost per token alone. In an edtech candidate-scoring workflow, count tokens plus retries, retrieval, timeout handling, and human review. Set three budgets before selecting a model or service: malformed-output…",
