The paper introduces a dReLU-based sparsification method and verifies its effectiveness on both dense and MoE LLMs. This approach significantly reduces computational demands, addresses environmental concerns through lower energy consumption, and helps democratize access to advanced AI technologies. We believe that our work can better support smaller organizations, educational institutions, and researchers, who previously faced barriers due to resource limitations, in accessing LLMs more easily.
