Broader Impact 7.4 Deploy LLMs on mobile phones We also serve TurboSparse-Mixtral-47B by using PowerInfer-2 that supports LLM inference on mobile phones. PowerInfer-2 leverages the sparse activation feature during LLM inference and introduces a computational engine on heterogeneous XPUs. It can perform high-speed inference even when the model parameters exceed DRAM capacity. As shown in Table 9, PowerInfer-2 achieves a 22.2× speedup using TurboSparse-Mixtral-47B inference compared to llama.cpp with the original Mixtral-47B. This significant performance gain is primarily because PowerInfer-2 can fully exploit the extremely high sparsity that TurboSparse demonstrates during inference. Authors:
