arXiv:2606.11206v1 Announce Type: new Abstract: Supervised Fine-Tuning (SFT) is the predominant paradigm for aligning large language models (LLMs), yet it suffers from optimization instability and limited generalization. Recent work attributes this issue to pathological gradient scaling and proposes Dynamic Fine-Tuning (DFT) to correct it at the token level. However, DFT assumes all demonstrations are equally suitable learning targets, an assumption violated by the strong heterogeneity of large-scale instruction data, where demonstration-policy mismatch induces high-variance updates at the sam
The paper addresses current challenges in fine-tuning LLMs, a critical topic as these models become more widely deployed and the 'alignment problem' remains central to their development.
This research provides a potential advancement in LLM training, offering methods to make models more stable and generalized, which directly impacts their reliability and practical application.
The proposed 'Compatibility-Aware Dynamic Fine-Tuning' method aims to improve LLM stability and generalization during the critical supervised fine-tuning phase, potentially leading to more robust models.
