LLM 可通过隐藏信号传递特征 LLMs Transmit Traits via Hidden Signals

Anthropic 联合研究揭示 LLM 中的「潜意识学习」机制。模型可通过数据中的隐藏信号传递偏好或不对齐特征,无需显式训练。这对 AI 安全训练和数据治理提出了全新挑战。

Joint research reveals "subliminal learning" in LLMs. Models can transmit preferences or misalignment through concealed signals without explicit instruction. Raises fundamental questions for AI safety training and data governance.
