What MoE means

A router selects experts per token instead of running every expert. Active parameters describe a compute slice; total parameters matter for storing and distributing weights. Runtime also needs cache and buffers. Neither number alone is a hardware requirement. Read the deployment preparation guide.

Features and verification

Mistral Chat Completion API defines the request format. Protocol support is not task accuracy.
