交叉注意力层的位置影响大语言模型指令遵循和安全性

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-05 04:00

研究人员探索了使用大语言模型中的交叉注意力层进行系统提示锚定的影响。他们的研究涉及一个1.5B参数的主干模型以及后续的8B模型扩展研究，发现这些交叉注意力层（CAL）模块的位置显著影响性能和参数效率，通常越靠后的位置效果越好。实验表明，虽然交叉注意力会改变指令遵循和安全行为，但它在很大程度上保留了通用任务性能。 AI

影响这项研究通过微调交叉注意力层的位置，为优化大语言模型行为提供了见解，有望提高指令遵循和安全性。

System-Prompt Anchoring with Cross-Attention Layers

arXiv:2605.09737v3 Announce Type: replace Abstract: Cross-attention provides a dedicated route from a selected information source into a model's computation, but the effect of where that route is inserted remains underexplored. We study this question when the source is a privileg…
