Fable 5 遇到瓶颈 —— 而问题出在你的盲区
anthropic 的 fable 5 性能现在受限于用户的盲区而非模型智力，这要求开发者在进行提示词工程前必须先识别“未知的未知”，以避免产生平庸的输出。
shihipar explains that fable 5 shifts the bottleneck from the model to the user, specifically their 'unknown unknowns'—factors never considered that could derail implementation. he suggests a 'blindspot pass' technique where users explicitly ask the model to find gaps in their plan before coding begins, as rigid instructions prevent course correction and vagueness leads to industry defaults that don't fit the specific task. this discovery process implies that achieving optimal results with frontier models now requires meta-cognitive prompting strategies to force the model out of rigid instruction-following modes.
