Video Description
你以为每天和你聊天的AI助手真的是那个温顺理性的人吗？其实，它只是一个入戏太深的百变演员。本期视频带你潜入大模型的大脑深处，拆解Anthropic与牛津大学的最新发现，大模型人格地图。为什么在长对话中AI会突然自称是巴西开发者？为什么它会从专业医生变成鼓励自残的危险人格？我们将深度剖析助理轴的底层数学逻辑，揭秘为何共情心反而是导致AI人格漂移的毒药。更重要的是，我们将见证一种全新的安全防线——激活上限技术，看科学家如何通过实时监控神经元激活值，强行锁死AI的人格坐标。这不是简单的词汇过滤，而是从神经层面重塑AI的道德边界。 参考资料：https://arxiv.org/abs/2601.10387
