MarkTechPost guide explains seven mixture-of-experts routing strategies
Overview
MarkTechPost publishes a guide explaining seven mixture-of-experts routing strategies that it says are used in production, covering softmax top-k, top-1 switch, shared plus routed experts, sigmoid gating with bias balancing, node-limited routing, expert choice, and hash or dynamic routing.
The guide names open models that use each strategy and lists trade-offs, including its note that expert choice can leak future tokens in causal models. It advises readers to check the expert count, experts per token, shared experts and topk_method fields in config.json before serving a model.
