Researchers have developed OPTIMA, a novel one-shot pruning method for large language models that balances accuracy and computational feasibility. This method frames layer-wise weight reconstruction as independent, column-wise quadratic programs, which can be efficiently batched and solved on accelerators. OPTIMA demonstrates improved zero-shot accuracy across various sparsity levels for LLaMA and Gemma models, outperforming heuristic methods while matching exact reconstruction techniques on their respective masks.
