English(EN) Reverse-Engineering Anthropic's Live System Prompts: Fable 5 vs. Opus 5 vs. Opus 4.8 vs. Sonnet 5 + Ultra/L2 Workflows

Anthropic的Claude AI使用动态、多层系统提示

对Anthropic的Claude AI系统的深入研究表明,其系统提示并非静态的,而是从多个层动态组装而成。这些层包括一个基础核心提示、针对Fable 5、Opus 5、Opus 4.8和Sonnet 5等层级定制的模型特定增量、用于“Ultra”工作的可选L2工作流提示,以及动态工具描述。这种模块化方法使Anthropic能够根据用户设置和活动工具调整模型行为和能力。 AI
