Anthropic 文档：提示词中代码归属表述影响 Claude Fable 5.2 重构行为

AI 摘要

Anthropic 在 Claude Fable 5.2 的文档中披露，模型对提示词中关于代码归属的表述高度敏感。在小规模编程任务测试中，若提示词未说明代码归属或暗示代码属于他人，模型倾向于沿用现有结构，即使会重复已有代码；若明确告知代码归模型自己所有，模型在约一半的尝试中会合并重复代码，而无此提示时该比例不足十分之一。

10th November 2026 Claude Fable 5.2 responds closely to what the prompt says about who owns the code it works on. In Anthropic’s testing on small coding tasks, when a prompt said nothing about ownership or presented the code base as someone else’s, the model tended to add to the existing structure, even when that repeated existing code. [...] If you want the model to improve the structure as it works, say that the code is its own: This codebase is yours: what it's for and how it's built are your
