	Experts within a MoE model are smaller, specialized neural networks trained to excel in specific domains or on particular types of problems. These experts can be various types of neural networks, such as Multi-Layer Perceptrons (MLPs), Convolutional Neural Networks (CNNs), or Recurrent Neural Networks (RNNs), each optimized for different kinds of data or tasks. They are akin to specialized components within the larger model that contribute to processing specific tokens or data points.

-State Space Models (SSMs) have become serious contenders in the field of sequential modeling, challenging the dominance of Transformers. At the same time, Mixture of Experts (MoE) has significantly improved Transformer- based LLMs, including recent state-of-the-art open-source models. We propose that to unlock the potential of SSMs for scaling, they should be combined with MoE. We showcase this on Mamba, a recent SSM-based model that achieves remarkable, Transformer-like performance. Our model, MoE-Mamba, outperforms both Mamba and Transformer-MoE. In particular, MoE-Mamba reaches the same performance as Mamba in 2.2x less training steps while preserving the inference performance gains of Mamba against the Transformer.
