What are the primary benefits of MoE over dense models?

MoE allows for significantly larger model capacity (total parameters) while keeping the compute cost (active parameters) constant, often resulting in a 5x cost reduction for similar performance levels.

How does this skill help with expert load balancing?

It provides implementation patterns for auxiliary loss and router Z-loss to ensure tokens are distributed evenly across experts, which is critical for maintaining training stability and expert utility.

Can I use these techniques to optimize model inference?

Yes, MoE is inherently an inference optimization. By only activating a subset of experts per token (e.g., top-2), you can run a model with high capacity at the speed of a much smaller dense model.

Which libraries does this skill support for MoE implementation?

The skill provides patterns and configurations for DeepSpeed, Megatron-DeepSpeed, and HuggingFace Transformers, enabling flexible integration into various training pipelines.
