Claude Code의 프롬프트가 80% 짧아졌다 — Fable 5에게 적을수록 더 좋은 이유
Anthropic은 Fable 5 모델이 더 적은 지침과 예시를 선호한다는 사실을 발견한 뒤 Claude Code의 시스템 프롬프트를 80% 축소했습니다. 이는 개발자들이 더 나은 성능을 위해 AI 모델을 최적화하는 방식을 바꿔놓고 있습니다.
anthropic has reduced claude code's system prompt by 80%, discovering that its fable 5 models perform better with less rigid instruction. engineer tariq shihipar notes that adding examples now tends to constrain the model's imagination rather than guide it, marking a reversal from previous engineering trends. the company now prioritizes context-based steering over explicit 'do not do this' constraints. this suggests that as models scale, their interaction patterns must fundamentally change to maximize utility.
