Complete-muE: Optimal Hyperparameter Transfer and Scaling for MoE Models

arXiv:2605.23893v1 Announce Type: new Abstract: We propose Complete-muE, a framework which targets hyperparameter transfer across dense FFN and any Mixture-of-Experts (MoE) setups in transformer blocks. Existing tools such as $\mu$P (requires fixed architectue) or SDE (requires fixed per-step token count) cannot directly solve the hyperparameter transfer problem in MoE setups because Dense to MoE transfer or MoE total experts scaling changes both architecture and tokens per expert. Complete-muE solves this challenge with a two-bridge system: Bridge~I maps between dense FFN and Dense MoE by act

Why this matters
Why now

The increasing scale and complexity of MoE models necessitate more efficient hyperparameter tuning and transfer methods to realize their full potential.

Why it’s important

This development could significantly accelerate the development and deployment of large-scale AI models by optimizing their training and scaling processes, reducing computational waste, and making MoE architectures more accessible.

What changes

The ability to optimally transfer hyperparameters across different AI model architectures, especially between dense FFNs and various MoE setups, makes scaling more predictable and resource-efficient.

Second-order effects
Direct

Faster and more efficient development of state-of-the-art AI models, potentially leading to more frequent model updates and new applications.

Second

Reduced operational costs for training and deploying large AI models could lower barriers to entry for some applications, but also concentrate power among those with vast compute.

Third

The democratization of MoE development tools could foster wider experimentation and novel AI architectures, potentially pushing the frontier of AI capabilities more rapidly.
