arXiv:2606.12921v1 Announce Type: cross Abstract: Low-Rank Adaptation (LoRA) significantly reduces compute and memory costs for finetuning Deep Learning models but is often harder to tune than dense training: when using factor-wise optimizers such as AdamW, it is sensitive to initialization choices, its optimal learning rates transfer poorly across ranks, and it often fails to beat dense baselines. We derive LoRA-Muon by applying the Muon optimizer's spectral steepest-descent rule to the low-rank setting. Along with our split weight-decay rule, our main claim is that LoRA-Muon is a good low-ra
The paper provides a significant advancement in fine-tuning large language models more efficiently, addressing known limitations of existing LoRA optimizers.
This development could accelerate the pace of AI model development and deployment by making fine-tuning more robust and less resource-intensive, impacting the accessibility and cost of advanced AI.
Fine-tuning Deep Learning models with LoRA becomes more stable and effective, potentially outperforming dense baselines and requiring less trial-and-error.
