  In the digital transformation era, Metaverse offers a fusion of virtual
reality (VR), augmented reality (AR), and web technologies to create immersive
digital experiences. However, the evolution of the Metaverse is slowed down by
the challenges of content creation, scalability, and dynamic user interaction.
Our study investigates an integration of Mixture of Experts (MoE) models with
Generative Artificial Intelligence (GAI) for mobile edge computing to
revolutionize content creation and interaction in the Metaverse. Specifically,
we harness an MoE model's ability to efficiently manage complex data and
complex tasks by dynamically selecting the most relevant experts running
various sub-models to enhance the capabilities of GAI. We then present a novel
framework that improves video content generation quality and consistency, and
demonstrate its application through case studies. Our findings underscore the
efficacy of MoE and GAI integration to redefine virtual experiences by offering
a scalable, efficient pathway to harvest the Metaverse's full potential.
