Analyzing Computational Savings in MoE Models
A standard large language model deployed across multiple devices activates all its parameters for every input. In contrast, a Mixture-of-Experts (MoE) model with the same total number of parameters often achieves faster processing. Explain the core architectural difference that allows the MoE model to reduce the computational cost per input.

Experts as Modular FFNs in LLM MoE Models
A large language model is deployed for inference across 8 powerful processing units. In one configuration, the entire model's computational graph is activated across all 8 units for every input. In a second configuration, the model is structured with 8 distinct 'expert' sub-networks, one on each unit. For a given input, a routing mechanism selects only the 2 most relevant expert sub-networks to perform computations. What is the primary efficiency benefit of the second configuration for processing this specific input?
