Claude Fable 5 won't answer basic biology questions despite being marketed for biology skills
Original: Claude Fable won’t answer basic biology questions
Anthropic's new flagship Claude Fable 5 refuses basic high-school biology questions, redirecting to its predecessor instead.
Anthropic launched Claude Fable 5 as its most powerful model yet, specifically touting its biology capabilities. However, users found the model refuses to answer basic high-school-level biology questions, instead handing queries off to the previous flagship model. The contradiction raises questions about overly aggressive safety filters undermining the model's advertised strengths.
Anthropic 於 2026 年 6 月發布了 Claude Fable 5,對外宣傳這是其有史以來向大眾廣泛開放的最強大 AI 模型。在官方介紹中,Anthropic 特別點名生物學作為 Claude Fable 5 的強項之一,暗示該模型在科學推理與知識深度上有顯著進步。然而,現實情況卻與行銷說法形成了鮮明落差。
