arXiv:2509.26169v2 Announce Type: replace Abstract: Alignment of large language models remains a central challenge in natural language processing. Preference optimization has emerged as a popular and effective method for improving alignment, typically through training-time or prompt-based interventions. In this paper, we introduce alignment-aware decoding (AAD), a method to enhance model alignment directly at inference. Theoretically, AAD can be interpreted as implicit reward optimization, yet it requires no specialized training beyond the standard DPO setup. Empirically, AAD consistently outp
The continuous challenge of aligning large language models with human preferences is driving ongoing research for more efficient and effective solutions, particularly at inference time.
This development proposes a method to significantly enhance LLM alignment and safety directly at the point of use, without requiring extensive additional training or prompt engineering.
Alignment-aware decoding could make LLMs more reliable and controllable, simplifying their deployment in sensitive applications and reducing the need for post-deployment fine-tuning.
