Research on Mixture of Experts routing topology in language models finds that multiple routing topologies achieve comparable language modeling performance (equifinality). This suggests routing architecture may not be a critical bottleneck in MoE design and informs architectural choices for large language model scaling.

Equifinality in Mixture of Experts: Routing Topology Does Not Determine Language Modeling Quality
Equifinality in MoE routing—multiple topologies achieve equivalent language modeling performance—removes routing architecture as a critical constraint in LLM scaling design.
