**TLDR:** Mixture of Experts (MoE) architecture: sparse activation, expert routing (top-k gating), Mixtral 8x7B (Jan 2024) open-source revolution, DeepSeek-V3 671B (Dec 2024) frontier. Routing math (Shazeer 2017 outrageously sparse), auxiliary loss, load balancing. Memory-efficient frontier scale models.
