A new study suggests that the low-rank assumption underlying LoRA and QLoRA fine-tuning methods may not hold true in production environments. While these techniques enable efficient adaptation of large language models on limited hardware, real-world applications often violate the assumption of uniform distribution, leading to performance issues. This finding could significantly impact the development and deployment of customized LLMs. AI
