Ehsan's Insight
Mixture of Experts (MoE) is the architecture behind the most efficient large models (Mixtral, GPT-4 is rumored to use MoE). Instead of activating all parameters for every input, MoE routes each token to a subset of specialized "expert" sub-networks. A 400B parameter MoE model might only activate 50B parameters per token, achieving quality comparable to a dense 400B model at the inference cost of a 50B model. The business implication: MoE models offer the best quality-to-cost ratio for diverse workloads because different experts specialize in different domains. As MoE architectures become standard, model selection increasingly favors MoE variants over dense models of comparable size.
