MoE (Mixture of Experts)

Friendly Description: Mixture of Experts is an AI design where the model is actually made up of many smaller specialists, and a smart router picks the right ones for each question. It's like calling a hospital and having the receptionist instantly route your call to the cardiologist, the radiologist, or the pediatrician depending on what you need. This approach lets a model be huge without being slow, because only a few experts work on any single request.

Example: When an MoE model is asked to write Python code, the router activates the experts that learned the most about programming. When it's asked to translate French poetry, a different set of experts steps in. The user never sees this happening; they just get fast, focused answers.
