-An intelligent **Mixture-of-Models (MoM)** router that acts as an Envoy External Processor (ExtProc) to intelligently direct OpenAI API requests to the most suitable backend model from a defined pool. Using BERT-based semantic understanding and classification, it optimizes both performance and cost efficiency.
+An **Mixture-of-Models (MoM)** router that intelligently directs OpenAI API requests to the most suitable models from a defined pool based on **Semantic Understanding** of the request's intent.
+
+This is achieved using BERT classification. Conceptually similar to Mixture-of-Experts (MoE) which lives *within* a model, this system selects the best *entire model* for the nature of the task.
