新工具MicroLens解码并重塑语言模型内部机制

研究人员开发了MicroLens,一个用于分析和修改语言模型内部工作机制的交互式工具。该工具利用两个不同的镜头——Logit Lens和Jacobian Lens (J-Lens)——来解码、追踪和编辑这些模型的残差流。在Gemma-3-4B-it上的实验表明,MicroLens可以揭示信息是如何被处理的,显示琐碎问题的关键信息在模型层早期就已存在,但并非总能在最终答案生成中被利用。该工具还强调,对于许多问题类型,在模型生成推理步骤之前,正确答案通常可以在残差流中预测出来。 AI

影响 提供了理解和调试LLM行为的新方法,可能加速模型可解释性和控制方面的研究。
