Mixture of Experts (MoE) is a model architecture that allows for a large number of parameters while keeping inference costs low. In MoE, a router network directs each token to a subset of specialized expert networks, rather than processing it through the entire model. This sparse activation decouples model capacity from computational cost, enabling the quality of massive models at a fraction of the expense. However, challenges include load balancing experts, managing memory for all experts, and potential training instability. AI
