This post extends the understanding of AI inference latency optimization by providing a deep dive into the arithmetic and deployment challenges specific to Mixture-of-Experts (MoE) models. It demystifies the '8x7B' notation, quantifies memory and FLOPs requirements for MoE inference (prefill and decode), and categorizes production bottlenecks based on hardware. While the previous post introduced REAP for pruning MoE models, this post focuses on the fundamental calculations and system-level considerations for running MoE inference efficiently.
