5 ways LLM service costs can unexpectedly increase

By PulseAugur Editorial · [1 sources] ·

This article discusses five common ways LLM service costs can unexpectedly increase, focusing on optimization strategies beyond just model selection. It highlights issues like redundant requests due to retries or double-button presses, prompt caching failures from dynamic elements, uncontrolled output length, and inefficient result page rendering. The author suggests implementing idempotency keys, optimizing prompt structure for caching, using format-based length control, leveraging HTTP caching for static results, and dynamically adjusting model 'thinking depth' based on task complexity to mitigate these cost leaks.

    5 Places Where Token Costs Actually Leak When Building Services with LLMs

    <p>LLM을 쓰는 서비스를 만들면 비용 이야기가 반드시 나옵니다. 그런데 처음 논의되는 건 대개 "어느 모델을 쓸 것인가"입니다. 실제로 청구서를 뜯어 보면 모델 선택보다 <strong>구조에서 새는 양</strong>이 더 큰 경우가 많습니다.</p> <h2> 1. 같은 요청을 두 번 부르는 것 </h2> <p>가장 흔하고 가장 조용한 낭비입니다. 사용자가 버튼을 두 번 누르거나, 결과가 안 나온다고 새로고침하거나, 네트워크가 끊겨서 재시도하는 상황입니다. 서버 입장에서는 정상 요청이라 로그에…
