Zero-order Parameter-free Optimization for LMO-based Methods: Novel Approach for Efficient Fine-tuning
arXiv:2606.14970v1 Announce Type: new Abstract: Fine-tuning large language models (LLMs) has become a central application of modern optimization, enabling pretrained models to adapt to diverse downstream tasks and domain-specific data. A major obstacle in large-scale fine-tuning is the memory overhead of backpropagation, which requires storing activations, gradients, and optimizer states. Zeroth-order (ZO) optimization offers a memory-efficient alternative, but its performance is highly sensitive to the stepsize and smoothing parameter, often requiring costly task-specific tuning.

The continuous growth in LLM size and complexity necessitates more efficient fine-tuning methods that address memory and computational constraints. Research is constantly pushing the boundaries of what is possible within these constraints.
This breakthrough addresses a critical bottleneck in large language model development, potentially reducing the cost and complexity of fine-tuning, making advanced AI more accessible and adaptable.
The reliance on complex, parameter-dependent optimization methods for fine-tuning LLMs could decrease, opening doors for more robust and resource-efficient training paradigms.
