# Rethinking CPU vs. GPU Roles for Faster LLM Inference

New research and engineering efforts are reviving the CPU as a key player in large language model inference, rather than relying solely on GPUs. By optimizing memory bandwidth and splitting workloads between CPU and GPU, systems can reduce cost and improve latency. This shift could reshape how AI infrastructure is designed for serving models.
