# 对齐算法的机制分析：六种优化方法对比研究

论文首次对六种语言模型对齐算法进行机制分析，包括PPO、DPO、SimPO等。研究揭示了这些方法如何重塑模型的内部计算，而不仅是黑盒评估。发现不同算法对模型参数的影响存在系统性差异，为改进对齐技术提供新思路。数据集和代码已公开。

## English Version

**Mechanistic Analysis of Six LLM Alignment Algorithms**

First mechanistic analysis of six LLM alignment algorithms (PPO, DPO, SimPO, etc.) reveals how they reshape model internals rather than just black-box evaluation. Finds systematic differences in how algorithms affect model parameters, offering new insights for improving alignment techniques. Dataset and code are publicly available.
