MoE Routing

Algorithm that selects which expert sub-networks process each input token.

Definition

Routing decides, for each token, which 1–2 of N experts to activate. Top-k softmax, expert-choice routing and load-balancing losses keep experts utilised evenly. Routing quality dominates the practical performance of MoE models like Mixtral and DeepSeek-V3.

Common use cases

  • MoE training
  • Expert load balancing
  • Inference efficiency
