Anthropic：让AI模拟多种人格

from 每日AI · host 每日新闻

探讨了人格选择模型 (PSM)，该模型认为大语言模型在预训练期间学习模拟多种人格，而后期训练则专门提取并塑造了一个**“助手”角色**。作者指出，用户与 AI 的交互本质上是在与这个模拟角色沟通，这解释了 AI 为何表现出拟人化的情感和行为。文中提供了来自泛化能力、行为观察及可解释性研究的证据，证明 AI 是在重用预训练中的人类概念，而非凭空产生意图。这种视角建议开发者应通过拟人化逻辑来预测 AI 心理，并引入正面角色模型来优化训练数据。最后，文章讨论了该模型的完备性，探讨了 AI 的代理权究竟是源于“助手”角色，还是来自底层模型中更隐秘的非人格化机制。The Persona Selection Model: Why AI Assistants might Behave like Humans
