해결법

messages = [{"role": "user", "content": [ {"type": "text", "text": system_prompt, "cache_control": {"type": "ephemeral"}} ]}]→ 캐시 히트 시 입력 토큰 비용 90% 절감
- 모델 라우팅 자동화:
def select_model(task_complexity): if complexity < 3: return "haiku" # $0.25/M if complexity < 7: return "sonnet" # $3/M return "opus" # $15/M - 컨텍스트 윈도우 감사:
tiktoken으로 각 요청의 토큰 수 로깅 → 가장 비싼 요청 식별 → 최적화 우선순위
