What is a Sparse Mixture of Experts？

Mixtral utilizes a sparse mixture of experts (SMoE) approach for efficiency. Instead of using all parameters simultaneously, it employs a router network to select a small group of experts for each input token. This targeted selection enhances performance by focusing on relevant model components and is done by a gating network in the moe layer. By activating only essential parameters, Mixtral achieves higher throughput and processes information faster, making it ideal for complex NLP tasks with large datasets.

Capabilities of Mixtral

Leveraging innovations like Grouped-Query Attention (GQA) and Sliding Window Attention (SWA), Mixtral excels in swiftly managing intricate tasks by leveraging model parallelism. Mixtral can divide complex problems into simpler ones with advanced training strategies. The weighted sum of outputs from diverse experts in the MoE layer enhances its performance by capturing complexities that single-structured models may miss.
