From: Do Mixture of Experts (MOE) Models Always Share Experts Across Layers?

Why might AI designers choose to share or not share experts in their models?

Designers balance limited computing power with the need for models to learn rich features. Sharing experts saves resources but can limit specialization; unique experts cost more but may learn better.

Action

If you try building a simple AI or learning model, experiment with reusing parts versus creating new ones for each step and see what works best.

Sharing experts across layers can save computational resources but may reduce model flexibility.

evidence

MOE models can have experts unique to each layer or shared across layers, depending on design.
